<p class="abstrak2">South Korea has declared to reduce greenhouse gas emissions by 30% compared to the current level by the year 2020. The greenhouse gas emissions from the cattle production sector in South Korea were evaluated in this study. The greenhouse gas emissions of dairy cattle, Non-Korean native cattle, and Korean native (Hanwoo) cattle production activities in 16 local administrative provinces of South Korea over a ten-year period (2005–2014) were estimated using the methodology specified by the Guidelines for National Greenhouse Gas Inventory of the IPCC (2006). The emissions studied herein included methane from enteric fermentation, methane from manure management, nitrous oxide from manure management and carbon dioxide from direct on-farm energy use. Over the last ten years, Hanwoo cattle production activities were the primary contributor of CH<sub>4</sub> from enteric fermentation, CH<sub>4</sub> from manure management, NO<sub>2</sub> from manure management and CO<sub>2</sub> from on-farm energy use in the cattle livestock sector of South Korea, which comprised to 83.52% of total emissions from cattle production sector.</p>

Full textAbstract:
The life cycle assessment component of this multi-institutional project determined greenhouse gas emissions in pre-farm, on-farm and post-farm activities involved in the use of maize for the manufacture of corn chips. When the emissions were expressed in terms of carbon dioxide-equivalents (CO2-e), pre-farm emissions comprised ~6% of the life cycle emissions, on-farm activities comprised ~36% and post-farm activities accounted for ~58% of life cycle greenhouse gas emissions. We used one 400 g packet of corn chips as the functional unit. The single largest source of greenhouse emissions was the emission of nitrous oxide on the farm as a result of fertiliser application (0.126 kg CO2-e per packet). The next largest was electricity used during the manufacture of the corn chips (0.086 kg CO2-e per packet). The manufacture of the packaging (box plus packet, being 0.06 kg CO2-e) was the next largest source and then the oil for frying the corn chips (0.048 kg CO2-e per packet). Greenhouse gas emissions from fertiliser application were primarily nitrous oxide (N2O), which has a global warming potential of 310 kg CO2-e/kg N2O. In typical irrigated farm systems, these emissions, when converted to CO2-e, are almost three times more than the greenhouse gas emissions that result from energy used to pump water. However, pumping irrigation water from deep bores currently produces greenhouse gas emissions that are almost three times those from irrigation using surface waters. Greenhouse gas emissions from the use of tractors on typical farms are about one-third of the emissions from pumping water. Farm management techniques can be used to increase soil carbon and reduce greenhouse gas emissions. If farms that currently burn stubble were to implement stubble incorporation then, in the absence of other changes to the supply chain, they will achieve a 30% reduction in emissions from ‘cradle to farm-gate’. In absolute terms, when the soil carbon dioxide is included (even though soil carbon dioxide in this instance is not counted as a greenhouse gas in national and international greenhouse gas inventories), our measurements indicate that carbon dioxide and greenhouse gas emissions from farms that produce maize using stubble incorporation are 56% lower than emissions from farms that burn their stubble. The pre-farm and on-farm operations add $0.40 value per kg of CO2-e greenhouse gas emitted. Post-farm processing added $2 value per kg of CO2-e greenhouse gas emitted. Processing maize for corn chips emitted more greenhouse gases than processing the same amount of corn for starch or ethanol.

The climate change policy is one of the key factors in the achievement of sustainable development in the Republic of Croatia. Control and mitigation of greenhouse gases is correlated with all economy activities. Waste management is one of the main tasks of environmental protection in Croatia. The Waste Management Strategy of the Republic of Croatia and the Waste Management Plan in the Republic of Croatia define the concept of waste management hierarchy and direct and indirect measures as criteria for sustainable waste management establishment. The main constituent of this system is avoiding and minimizing waste, as well as increasing the recycling and recovery level of waste and landfill gas, which also represent greenhouse gases mitigation measures. The Waste Management Plan consists of several direct and indirect measures for greenhouse gases emission reduction and their implementation also affects the greenhouse gases emissions. The contribution of the methane emission from landfills amounts to about 2% of the total greenhouse gases emissions in Croatia. The climate change control and mitigation measures as an integral part of waste management sector strategies represent the measures of achieving the national objectives towards greenhouse gases emission reduction which Croatia has accepted in the framework of the Kyoto Protocol.

Mankind’s rapidly increasing advancements in different industrial sectors demand a great price of environmental impact and climate change in return, specifically in the buildings and construction industry. The largest source of greenhouse gas emissions and energy consumption worldwide are buildings, estimated to account for almost 48% of all such emissions. Energy-related Carbon Dioxide (CO2) counts for about 82% of all greenhouse gases emitted by human activities. This total energy consumption translates to approximately 3.5 Billion Euros per annum. According to a report from the United Nations Environment Programme, the right mix of appropriate government regulations, greater use of energy-saving technologies and user behavioural changes can substantially reduce CO2 emissions from buildings. The Energy Performance of Buildings Directive places an onus on all EU member states to rate the energy performance of buildings in a Building Energy Rating certificate which is effectively an energy label required at the point of rental ...

Full textAbstract:
The consumption of renewable energy sources results in the minimal production of greenhouse gases. However, the issue of environmentally efficient use of renewable energy sources remains a key concern. The primary aim of this article was to assess whether the energy production from renewable energy sources was environmentally efficient in four selected European countries: Germany, Austria, Poland, and the Czech Republic. In order to achieve the primary research goal, a regression analysis method was used for several variables. The results of the analysis suggested that with an increase in the consumption rate of renewable energy sources and biofuels equivalent to one thousand tons of oil, the volume of emissions from all sectors would increase by 0.0048 thousand tons (4.8 tons) on average. The system of emission allowances was rather environmentally inefficient at the lower allowance levels; in the monitored period of 2007 to 2016, the dependence of greenhouse gas production on the consumption of fossil fuels did not statistically manifest itself. Based on the analysis, the land use, land-use change, and forestry production activities do not contribute to increasing total greenhouse gas emissions.

Abstract To reduce emissions of greenhouse gas (GHG) from landfills, the European Union (EU) Landfill Directive 1999/31/EC requires that there be a progressive decrease in the municipal biodegradable waste disposal. The main problem of waste management (WM) in Latvia is its heavy dependence on the waste disposal at landfills. The poorly developed system for the sorted municipal waste collection and the promotion of landfilling as a major treatment option led to the disposal of 84% of the total collected municipal waste in 2012, with a high biodegradable fraction. In Latvia, the volume of emissions due to activities of the WM branch was 5.23% (632.6 CO2 eq.) of the total GHG emissions produced in the National economy in 2010 (12 097 Gg CO2 eq., except the land use, land-use change and forestry). Having revised the current situation in the management of biodegradable waste in Latvia, the authors propose improvements in this area. In the work, analysis of environmental impact was carried out using Waste Management Planning System (WAMPS) software in the WM modelling scenarios. The software computes the emissions, energy and turnover of waste streams for the processes within the WM system such as waste collection and transportation, composting, anaerobic digestion, and the final disposal (landfilling or incineration). The results of WAMPS modelling are presented in four categories associated with the environmental impact: acidification, global warming, eutrophication and photo-oxidant formation, each characterised by a particular emission. These categories cover an integrated WM system, starting with the point when products turn to waste which is then thrown into the bin for waste at its generation source, and ending with the point where the waste transforms either into useful material (recycled material, biogas or compost) or contributes to emissions into environment after the final disposal at a landfill or an incineration plant

Widespread interference of human activities has resulted in major environmental problems, including pollution, global warming, land degradation, and biodiversity loss, directly affecting the sustainability and quality of the environment and ecosystem. The study aims to address the impact of the extraction of natural resources and globalization on the environmental quality in the South Asian countries for the period 1991–2018. A new methodology Dynamic Common Correlated Effects is used to deal with cross-sectional dependence. Most previous studies use only carbon dioxide emissions, which is an inadequate measure of environmental quality. Besides carbon dioxide emissions, we have used other greenhouse gas emissions like nitrous oxide and methane emissions with a new indicator, “ecological footprint”. Long-run estimation results indicate a positive and significant relationship of natural resources with all greenhouse gas emissions and a negative association with the ecological footprint. Globalization shows a negative association with carbon dioxide emissions and nitrous oxide emissions and a positive relationship with the ecological footprint. Institutional performance is negatively correlated with carbon dioxide emissions, methane emissions, and ecological footprint while positively associated with nitrous oxide emissions. The overall findings highlight the pertinence of reducing greenhouse gas emissions and ecological footprint, proper utilizing of natural resources, enhancing globalization, and improving institutional performance to ensure environmental sustainability.

Full textAbstract:
The cycle of key nutrient elements nitrogen (N) and phosphorus (P) has been massively altered by anthropogenic activities. Little is known about the impacts on greenhouse gas (GHG) emission of the large nutrient additions occurring in the alpine grasslands of the Tibetan Plateau. We investigated soil surface emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) under control, N, P and combined nitrogen and phosphorus (NP) additions from July 2011 to September 2012. Compared to the control, CO2 flux significantly increased by 14.6% and 27.4% following P and NP addition, respectively. The interaction of NP addition had a significant influence on CO2 flux during the non-growing season and the spring thaw period. Compared to the control, CH4 flux decreased by 9.9%, 23.2% and 26.7% following N, P and NP additions, respectively, and no interactive effect of NP addition was found in any period. Soil N2O flux was significantly increased 2.6 fold and 3.3 fold, following N and NP addition treatments, respectively, and there was no interaction effect of NP addition together. The contribution of cumulative CO2 emission during the non-growing season was less than 20% of the annual budget, but cumulative CH4 and N2O emissions during the same period can account for 37.3–48.9% and 44.7–59.5% of the annual budget, respectively. Methane and N2O emissions did not increase greatly during the spring thawing period, with contributions of only 0.4–3.6% and 10.3–12.3% of the annual budget, respectively. Our results suggest that N and P addition could increase CO2 and N2O emissions and reduce CH4 emission. Furthermore, although the non-growing season is very cold and long, cumulative CH4 and N2O emissions are considerable during this period and cannot be neglected by future studies evaluating the greenhouse gas emission budget in the Tibetan plateau.

Full textAbstract:
The release of CO2 into the atmosphere - and more specifically its consequential effect on global temperature – is now more-or-less universally acknowledged as a significant international environmental problem. Known colloquially as the Greenhouse Effect, it is the subject of the UN Framework Convention on Climate Change. That convention commits its signatories to specific actions directed at stabilising emissions of greenhouse gases (including CO2) at 1990 levels. It was signed at the UN Conference on Environment & Development (the “Earth Summit” which was held in Rio de Janeiro in 1992) by 153 countries including New Zealand. New Zealand has now officially ratified the Convention and has thus effectively committed itself to participate in international programmes of CO2 emission reduction. The Resource Management Act 1991 requires regulatory authorities to consider the environmental effects of activities in their jurisdiction. Carbon dioxide is now considered to be a “contaminant” as defined in the Act and it therefore becomes contingent upon local authorities to determine a suitable response to the problem of CO2 emissions. Regional and district policy statements and plans are required to be consistent with the national policy statement. Although a national policy statement on CO2 emissions does not yet exist it can be expected that eventually the approval of resource consents for oil and gas exploration and production activities typically will require specific actions relating to the release of CO2. The increase of CO2 in the atmosphere is almost entirely the direct result of two fundamental and worldwide activities: the combustion of fossil fuels and the removal of forest cover. When burned, hydrocarbons add large quantities of CO2 to the atmosphere. The removal of forest cover reduces the ability of the ecosystem to extract CO2 from the atmosphere by photosynthesis. The oil and gas industry is, of course, the source of a large proportion of the hydrocarbons used for energy and other purposes. It can therefore be expected that governments (including New Zealand) will focus on various aspects of the industry in their efforts to meet the reduction goal. Until recently the central Government approach to CO2 emission reduction was to implement the so-called no regrets policies which are desirable goals (e.g. increased energy efficiency) which have the positive spin-off effect of reducing CO2 emissions. By themselves such policies are likely to be inadequate to meet the internationally accepted reduction target. The Government must therefore implement more stringent measures. As the matter now stands the Government is investigating a diverse range of methods for reducing CO2 emissions. Because CO2 emissions and energy use are inextricably linked, reducing CO2 emissions can clearly have a detrimental effect on economic development. The 'holy grail' of policy development in this area is to reduce CO2 emissions without producing harmful effects on the economy. Several options (and myriad variations on the theme) have been put forward including, for example, carbon taxes and tradeable quotas. These options and others are now being assessed by Government officials. The industry should be alert to the distinct possibility that policy will focus directly on oil and gas production. From a regulatory point of view such an approach has an enticing simplicity but the effect on the oil and gas industry may prove to be less than desirable.

The implementation of cutting-edge agricultural practices provides tools and techniques to drive climate-smart agriculture, reduce carbon emissions, and lower the carbon footprint. The alteration of climate conditions due to human activities poses a serious threat to the global agricultural systems. Greenhouse gas emissions (GHG) from organic waste management need urgent attention to optimize conventional composting strategies for organic wastes. The addition of various inorganic materials such as sawdust and fly ash mitigate GHG during the vermicomposting process. This paper critically investigates the factors responsible for GHG emissions during vermicomposting so that possible threats can be managed.

Greenhouse gas emissions (GHG), as well as other gaseous emissions and agronomic variables were continuously measured for three years (2011/2012 – 2014/2015) at eight experimental field sites in Germany. All management activities were consistently documented. The GHG-DB-Thuenen stores these multi-variable data sets of gas fluxes (CO2, N2O, CH4 and NH3), crop parameters (ontogenesis, aboveground biomass, grain and straw yield, N and C content, etc.), soil characteristics (nitrogen content, NH4-N, NO3-N, bulk density etc.), continuously recorded meteorological variables (air and soil temperatures, radiation, precipitation, etc.), management activities (sowing, harvest, soil tillage, fertilization, etc.), and its metadata (methods, further information about variables, etc.). In addition, NOx data were measured and analyzed. Also available are site-specific calculated C and N balances for the respective crops and crop rotations.

The manufacturing industry is one of the most influential sectors contributing to greenhouse gas emissions. As the manufacturing industry strives to achieve its profit goal, most of them face various circumstances to control the rising carbon emissions from the energy, raw material consumption, and waste generations due to production activities. Therefore, it is difficult to quantify the amount of carbon emission reduction if the adjustment is not established according to the manufacturing output. This research concentrates on evaluating energy consumption and waste generation using a statistical approach by a coconut milk processing plant. This research aims to estimate the reduction of greenhouse gas emissions, mainly carbon dioxide (CO2). The baseline models of energy consumptions and waste generations were constructed using single and multiple linear regression methods. Besides, it investigates the performance of ultimate models of electrical consumption, water consumption, fuel consumption, solid waste generation, and wastewater generations using statistical analysis that involves coefficient of correlation, coefficient of determination, analysis of variance (ANOVA), etc. It indicates that with the implementation of the cleaner production (CP) strategy, the plant had reduced 10,474.94 tons of CO2 and 2,579.67 tons of CO2 in 2018 and 2019, respectively. This study is an aid to the management and engineers of the industry to investigate their accomplishment in reducing environmental impacts caused by production activities from any implementation made such as CP and green industry practices.

Full textAbstract:
The baselines for greenhouse gas (GHG) and greenhouse gas reduction scenarios were approximated in Thailand so that a small-scale Clean Development Mechanism (CDM) could be introduced into other Association of Southeast Asian Nations (ASEAN) countries. In developing countries, a CDM is defined as the certified emission reduction from a baseline of any project (i.e. by applying new technologies) that could be exchanged for credits, and this credit of certified emission reductions could be acquired by Japan and ASEAN countries. Small-scale CDMs are project activities that reduce anthropogenic emissions and directly emit less than 15 kt of carbon dioxide-equivalents annually. For the success of CDM projects, baseline methodologies are allowed to apply to the United Nations CDM Executive Board. Baseline methodologies use a baseline scenario, which compares the baseline without any project to a case with an emission reduction project. After commencement of a project, reduction of GHG emissions from the baseline by the emission’s reduction project could be exchanged for credit. Therefore, GHG emission from the broiler industry in Thailand was calculated by the Tier 1 method and defaults data in accordance with 2006 IPCC guidelines. The baseline for the waste management system in the broiler industry is defined as drying without energy. Three types of projects on waste management systems the broiler industry were compared: (i) incineration, (ii) drying without energy input and (iii) drying with energy input. Products of these systems are finally used as compost on agricultural fields. The baseline for the manure drying without energy input system was approximated. This baseline was compared with the manure incineration system and the drying with energy input system. GHG emissions produced by adoption of drying broiler manure with energy input could be reduced by ~57% by drying broiler manure without energy input. This reduction in GHG (57%) could be credited to a small-scale CDM when operational. In the future, measurement of GHG on broiler production farms in Thailand should be considered, because estimation with the Tier 1 method, as performed in this study, may not be rigorous enough to be accepted by the CDM Executive Board. After compiling GHG inventories, baseline emissions would be known for the broiler industry in Thailand and other countries in ASEAN. These could then be used to advance CDM.

Salt-affected soils contain high levels of soluble salts (saline soil) and exchangeable sodium (alkali soil). Globally, about 932 million ha (Mha), including 831 Mha of agricultural land, is salt-affected. Salinity and sodicity adversely affect soil microbial diversity and enzymatic activities, and thereby carbon and nitrogen dynamics and greenhouse gas (GHG) emissions from soils. In this review article, we synthesize published information to understand the impact of salinity and sodicity on GHG production and emissions from salt-affected soils, and how various reclamation amendments (gypsum, phosphogypsum, organic manure, biochar, etc.) affect GHG emissions from reclaimed soils. Nitrous oxide (N2O) and methane (CH4) emissions are of greater concern due to their 298 and 28 times higher global warming potential, respectively, compared to carbon dioxide (CO2), on a 100-year time scale. Therefore, CO2 emissions are given negligible/smaller significance compared to the other two. Generally, nitrous oxide (N2O) emissions are higher at lower salinity and reduced at higher salinity mainly due to: (a) higher ammonification and lower nitrification resulting in a reduced substrate for denitrification; (b) reduced diversity of denitrifying bacteria lowered down microbial-mediated denitrification process; and (c) dissimilatory nitrate reduction to ammonium (DNRA), and denitrification processes compete with each other for common substrate/nitrate. Overall, methane (CH4) emissions from normal soils are higher than those of salt-affected soils. High salinity suppresses the activity of both methanogens (CH4 production) and methanotrophs (CH4 consumption). However, it imposes more inhibitory effects on methanogens than methanotrophs, resulting in lower CH4 production and subsequent emissions from these soils. Therefore, reclamation of these soils may enhance N2O and CH4 emissions. However, gypsum is the best reclamation agent, which significantly mitigates CH4 emissions from paddy cultivation in both sodic and non-sodic soils, and mitigation is higher at the higher rate of its application. Gypsum amendment increases sulfate ion concentrations and reduces CH4 emissions mainly due to the inhibition of the methanogenesis by the sulfate reductase bacteria and the enhancement of soil redox potential. Biochar is also good among the organic amendments mitigating both CH4 and N2O emission from salt-affected soils. The application of fresh organic matter and FYM enhance GHG emissions for these soils. This review suggests the need for systematic investigations for studying the impacts of various amendments and reclamation technologies on GHG emissions in order to develop low carbon emission technologies for salt-affected soil reclamation that can enhance the carbon sequestration potential of these soils.

Keynote paper presented at the International Leucaena Conference, 1‒3 November 2018, Brisbane, Queensland, Australia.The Australian Government has committed to reducing its greenhouse gas (GHG) emissions by 26‒28% below 2005 levels by 2030. The Emissions Reduction Fund (ERF), a center-piece of Australia’s climate change policies, provides incentives to reduce GHG emissions through economy-wide eligible activities, such as energy efficiency, waste management, revegetation, livestock management and savanna fire management. Emissions Reduction Fund methods define eligible activities, how to quantify abatement resulting from the activity and the required compliance measures.The requirements for developing ERF methods that quantify GHG abatement estimates resulting from eligible activities are described. Leucaena planting is used as an example. For an ERF method to be made and maintained, the activity must meet all the legislative requirements. This includes meeting the offsets integrity standards and having regard to any adverse environmental, economic and social impacts.

Previous studies on the effectiveness of improving sustainable development have acknowledged the importance of domestic research and development (R&D) activities. However, these studies remain general and ambiguous because they assume that all R&D activities are related to energy-saving and sustainable development. The corresponding empirical evidence is scabrous and ambiguous. In this paper, we focus on the effect of green innovation R&D activities on SO2 emission which is an important greenhouse gas affect global climate change and eco-civilization. Considering that there is heterogeneity exists in the innovation activities, the R&D activities are divided into three performers with two purposes. The empirical results based on a Chinese inter-provincial dataset of 2000-2016 suggest that the green innovation R&D activities are crucial for the reduction of the SO2 emission. However, the innovation R&D activities of different purposes and performers show statistically differentiated effects on SO2 emission. The major positive effect of green innovation R&D activities on SO2 emissions reduction is mainly from enterprises and utility-type of R&D activities. A further study based on the panel threshold also indicates that effects of green innovation R&D activities on SO2 emissions are nonlinear, depending on the technology absorptive ability.

In this work, for use as a unified tool within the framework of ISO 50001, a methodology for rating assessment of the processing of emissions with global pollutants is proposed, which was developed by the authors and recommended for use by state documents of the Republic of Tatarstan, Russia. It is distinguished by the absence of not transparences elements. As the initial data, the actual background concentrations (according to WMO data), the annual ceiling of greenhouse gas emissions and the maximum permissible emissions of toxic compounds, information on the characteristics of emission sources are taken for the enterprise, and as operational constants, the global warming potentials of greenhouse gases (GWP100) and officially approved values of maximum permissible concentrations of toxic compounds (MPC). The method is based on the equation (presented here at annotation in a simplified form), which gives a numerical indicator (rating) R of the efficiency of a production facility in terms of hazardous emissions into the atmosphere, taking into account greenhouse gases and energy costs arising from their removal. Currently, the technique is adapted to the energy sector; for wider adaptation to various industries, a low-carbon rating program has been drawn up for boiler houses, thermal power plants and industrial enterprises. It also meets the needs of understanding and predicting possible deviations of emission parameters from the standardized indicators. Therefore, it can serve as a tool within the framework of ISO 50001, providing objective control over the choice of means to ensure compliance with the requirements for harmful components emissions including greenhouse gases in the design and modernization of production facilities. The developed program is embedded for Russian enterprises in the shell of the ‘1C: Enterprise’ platform – a software product for automating accounting and management at enterprises. The program can also be used in the software shell of the automated accounting of the activities of a particular organization in a one or the other country.

South Africa is a signatory to the United Nations Framework Convention on Climate Change (UNFCCC) and as such is required to report on Greenhouse gas (GHG) emissions from the Energy, Transport, Waste and the Agriculture, Forestry and Other Land Use (AFOLU) sectors every two years in national inventories. The AFOLU sector is unique in that it comprises both sources and sinks for GHGs. Emissions from the AFOLU sector are estimated to contribute a quarter of the total global greenhouse gas emissions. GHG emissions sources from agriculture include enteric fermentation; manure management; manure deposits on pastures, and soil fertilization. Emissions sources from Forestry and Other Land Use (FOLU) include anthropogenic land use activities such as: management of croplands, forests and grasslands and changes in land use cover (the conversion of one land use to another). South Africa has improved the quantification of AFOLU emissions and the understanding of the dynamic relationship between sinks and sources over the past decade through projects such as the 2010 GHG Inventory, the Mitigation Potential Analysis (MPA), and the National Terrestrial Carbon Sinks Assessment (NTCSA). These projects highlight key mitigation opportunities in South Africa and discuss their potentials. The problem remains that South Africa does not have an emissions baseline for the AFOLU sector against which the mitigation potentials can be measured. The AFOLU sector as a result is often excluded from future emission projections, giving an incomplete picture of South Africa’s mitigation potential. The purpose of this project was to develop a robust GHG emissions baseline for the AFOLU sector which will enable South Africa to project emissions into the future and demonstrate its contribution towards the global goal of reducing emissions.

Full textAbstract:
The Great Plains region of the United States is an agricultural production center for the global market and, as such, an important source of greenhouse gas (GHG) emissions. This article uses historical agricultural census data and ecosystem models to estimate the magnitude of annual GHG fluxes from all agricultural sources (e.g., cropping, livestock raising, irrigation, fertilizer production, tractor use) in the Great Plains from 1870 to 2000. Here, we show that carbon (C) released during the plow-out of native grasslands was the largest source of GHG emissions before 1930, whereas livestock production, direct energy use, and soil nitrous oxide emissions are currently the largest sources. Climatic factors mediate these emissions, with cool and wet weather promoting C sequestration and hot and dry weather increasing GHG release. This analysis demonstrates the long-term ecosystem consequences of both historical and current agricultural activities, but also indicates that adoption of available alternative management practices could substantially mitigate agricultural GHG fluxes, ranging from a 34% reduction with a 25% adoption rate to as much as complete elimination with possible net sequestration of C when a greater proportion of farmers adopt new agricultural practices.

Full textAbstract:
The upstream oil and gas industry is diverse and many of the assets are geographically dispersed in offshore and onshore locations. The first year of National Greenhouse and Energy Reporting (NGER) in the 2009 financial year (FY09) challenged the industry to come to terms with complex issues such as the reporting structure, defining facilities, determining appropriate reporting methodologies, determining incidental emissions, obtaining contractor emissions and considering uncertainty estimates. This paper will explore the range of industry responses during FY09 and will be accompanied by a case study from Santos Limited to illustrate the journey. In responding to NGER requirements in FY09, the oil and gas industry was required to absorb many new legislative compliance obligations. At a company level, difficult decisions had to be made about the allocation of resourcing for NGER preparation and response. Companies were also faced with financial implications of the reported data, because that data would underpin permit liability under the proposed Carbon Pollution Reduction Scheme (CPRS). Going forward, a key optimisation challenge for FY10 and beyond is the management and use of the NGER data. This paper will cover the processes and systems used to collect and report data and how the use of that data for organisational decision making will all be an important optimisation consideration in a CPRS environment. The paper will also explore other NGER reporting issues for the oil and gas industry, such as: arrangements with stakeholders, such as joint venture parties, partners and contractors; selection of measurement methods, including complexities with venting, flaring and other fugitive emissions; availability of appropriate measurement equipment; issues with reporting of own-use emissions and intermediate energy use and production; and, measurement of exploration activities. These issues are likely to present an optimisation challenge to many in the industry during FY10 and beyond. The paper will then conclude with a case study by Santos Limited.

Full textAbstract:
Earthwork, an essential activity in most construction projects, consumes large quantities of fossil fuel and produces substantial air pollution with adverse environmental impacts. To achieve more sustainable construction processes, novel methodologies to evaluate and improve the performance of earthwork operations are required. This study quantifies the real-world emissions and fuel consumption of construction equipment within an earthwork project in China. Two wheel loaders and two dump trucks are examined through on-board measurements and in-lab engine tests. The duty cycles of construction equipment are categorized with respect to their power efficiency and working patterns. Moreover, the power-specific and time-based emission factors for these duty cycles are computed and compared with relevant legislative emission limits. Significant emission variations among different duty cycles were found, and the real-world emission measurements exceeded the results from the in-lab test required for emission certification. In addition, a discrete-event simulation (DES) framework was developed, validated, and integrated with the computed emission factors to analyze the environmental and energy impacts of the earthwork project. Furthermore, the equipment fleet schedule was optimized in the DES framework to reduce greenhouse gas emissions and fuel consumption by 8.1% and 6.6%, respectively.

Full textAbstract:
Awareness of the challenges of sustainable development, and in particular the risks of climate change, is leading to inevitable restrictions on Greenhouse gas emissions. True carbon risk management must be introduced into the strategy of companies that will increasingly operate in a global low-carbon economy. Indeed, companies are now called upon to be accountable and transparent about the environmental consequences of their business activities. Carbon risk is one of several new emerging risks for companies associated with climate change risks, regulatory risks from climate policies and the introduction of new markets in which companies trade emission credits. Carbon management requires companies to have a better understanding of their GHG emissions to assess their environmental responsibility and to know their degree of exposure to carbon risk. Once this assessment has been carried out, the company must adopt a carbon risk communication strategy, define targets, and implement abatement practices. Dalsey, Hillblom and Lynn is the world's leading logistics company and emits around 29 million tonnes of CO2e per year. DHL prioritises accounting, disclosure, energy efficiency and offsets to reduce its emissions. The company is struggling to reduce its emissions but is limiting the increase in emissions despite the increase in its activity. DHL needs to be more rigorous in developing better carbon management tools and giving itself the means to achieve very high targets.

(1) Background: Increased attention has been paid to atmospheric nitrogen (N) deposition caused by human activities. N deposition quantity has seriously affected plant productivity and greenhouse gas emissions in wetlands, but the effects of N deposition frequency remain unclear. (2) Methods: We assembled microcosms, which contained vegetative individuals (ramets) of Hydrocotyle vulgaris and soil and subjected them to three frequencies (N addition 1, 2, and 14 times during the experimental period) crossed with three quantities (5, 15, and 30 g N m−2 yr−1) for 90 days. (3) Results: The quantity of N addition significantly increased the root, stem biomass, and ramets number of H. vulgaris, but decreased the spike biomass. N addition quantity significantly promoted N2O emission and inhibited CH4 emission but had no significant effect on CO2 emission. The increasing frequency of N addition significantly promoted the root-to-shoot ratio and decreased N2O emission under high N addition quantity. (4) Conclusions: In conclusion, N addition alters the reproductive strategy of H. vulgaris and enhances its invasiveness, promoting N2O emission but not the CO2 equivalent of the H. vulgaris-soil system.

Full textAbstract:
Ship building, as an energy-intensive sector, produces significant amounts of air emissions, including greenhouse gases. Most research in greenhouse gas reductions from shipping concentrates on the reduction in emissions during the operational phase. However, as emissions during ship operation are reduced, the construction and dismantling phases of ships are becoming increasingly important in the assessment of the life-cycle impact of ships. In this study, priorities for a Turkish shipyard to become energy efficient were identified by means of a semi-structured questionnaire and an interview. This was undertaken using Fuzzy Multi-Criteria Decision-Making methods, including the Fuzzy Analytical Hierarchy Process and Fuzzy Order of Preference by Similarity to Ideal Solution, which are part of a proposed systematic and transdisciplinary Energy Management Framework and System. By applying Multi-Criteria Decision-Making methods, this framework supports the shipyard’s decision makers to make rational and optimized decisions regarding energy sectors within their activities. Applying the framework has significant potential to help achieve good product quality while reducing costs and environmental impacts, and can thereby enhance the sustainability of shipping. Moreover, the framework can boost both business and socio-economic perspectives for the shipyard, and improve its reputation and competitiveness, in alignment with achieving the Nationally Determined Contributions of States under the Paris Agreement.

Full textAbstract:
In the last few decades, climate change and the global warming have emerged as important environmental issues. The cause of global warming is the increase of greenhouse gas emissions (GHG). There are several greenhouse gases responsible for global warming: water vapor, carbon dioxide (CO2), methane, nitrous oxides, chlorofluorocarbons (CFCs) and others. They are mostly the result of the fossil fuels' combustion in cars, buildings, factories, and power plants. The gas responsible for the most of the global warming is carbon dioxide (CO2). This increase in the greenhouse gas emissions leads to a greater interest of the consumers, board management and stakeholders in the environmental impact of their activities, products and services.The verification of the Carbon Footprint of distribution oil immersed transformer, presented in this paper, was recognized as an opportunity for the company to understand its own environmental impact and to identify inefficiencies and opportunities within its business.Carbon Footprint of a Product (CFP) is a rather new term closely related to the greenhouse gas emissions. The CFP is considered as a total of the greenhouse emissions generated during the life cycle of a product – that is, from raw material acquisition or generation from natural resources to a final disposal. It is described within the standard ISO 14067:2018 Carbon footprint of products – Requirements and guidelines for quantification [1]. This standard belongs to the environmental series ISO 14000 and enables the organization to demonstrate its environmental responsibility.Life Cycle Assessment (LCA), as well as the Carbon Footprint of products together with environmental impact of the product, are shown in this paper in accordance with standard ISO 14067:2018. The LCA is a method for the quantification of the environmental impacts of individual products. It takes into account a complete life cycle, starting from a raw material production, until the product’s final disposal or materials’ recycling in accordance with ISO 14040 [2] and ISO 14044 [3]. Greenhouse gases are expressed in mass-based CO2 equivalents (CO2e), which is the unit of measurement in the ISO 14067:2018 standard. The functional unit in ISO 14067:2018 can be either a product or a service. In this paper, the functional unit was the product – oil immersed distribution transformer, in four product variations. The LCA scope used in the preparation of this study was "cradle to gate" – it covers the CFP from the acquisition of the raw materials ("cradle") up to dispatch from the factory ("gate").The objectives of product life cycle considerations in Končar D&ST Inc. are to reduce the use of natural resources and emissions to the environment, as well as to improve social performance at different stages of the product life cycle.By linking the economic and ecological dimension of the production, different aspects during realization of product in all phases of the life cycle come together. In this way company achieves cleaner products and processes, competitive advantage in the market and improved platform that will meet the needs of the changing business climate.Lifecycle thinking is based on the principles of reducing environmental impacts at the beginning of product creation, giving a wider picture of material and energy flow and ultimately environmental pollution prevention. These principles are organized in Končar D&ST Inc. internally by planning and introducing cleaner manufacturing processes, environmental protection management and eco-design.Incorporating ISO 14067:2018 into company business is recognized as an opportunity for transparent communication to interested parties, incorporating CO2 emissions into annual reports and as a baseline information for a first step towards managing carbon emissions.

Every engineer and manager knows that you can only improve performance that you measure and track. That is why we have key performance indicators (KPIs). Similarly, we can only optimize what we can predict. If we really want to lower carbon emissions, we will need to implement a consistent method of measuring and tracking the right data. There are challenges in improving what we track because tracking comes from so many sources. We need to work on optimizing what we predict if we are going to start making high-value decisions around emissions. Carbon emissions occur during all phases of the hydrocarbon extraction industry right through to the final use of the product. We call the total life cycle of emissions “well to wheels.” SPE members are generally focused on one phase of the carbon emissions. The largest contribution is the combustion and use of produced oil, from refinery to wheels. This is typically about 350–400 kg of CO2 equivalent per barrel. We use CO2 equivalent to include the greenhouse-gas (GHG) impact of methane. Then, there is the energy and carbon expenditure of producing that hydrocarbon, well to refinery. This includes drilling, completions, production, and transportation. Carbon emissions from the wells to refinery vary from less than 25 kg to more than 300 kg CO2 equivalent per barrel, aver-aging about 100. Flaring and fugitive emissions are generally the largest contributors to these emissions. Environmental, social, and governance (ESG) activism is driving changes in behavior for public investors, private investors, lenders, and management teams. When will the measuring be done? Who will set the industry standards? How will the model be developed? Carbon emissions from shale production vary dramatically and are also driven by flaring and fugitives. While flaring is preferable to venting, most low-volume flares are inefficient. Operators flare for a variety of reasons including lack of pipeline capacity, upsets, and low value for natural gas. Fugitive emissions also enter the equation. Fugitive emissions are any leakage or irregular release to the atmosphere of natural gas. This can be caused by human error, mechanical operations (such as pneumatic actuators), or faulty equipment. Fugitive emissions and flaring both factor into the well-to-reservoir carbon footprint. Many operators already report the carbon intensity of their activities, usually prior-year activities. Carbon intensity is the carbon emissions per unit of energy or per barrel. A variety of regulatory bodies and others argue the definitions of such reporting. We are arguing for reporting estimated carbon intensity of reserves.

Full textAbstract:
Nature-based conservation management (NBCMs) estates are seen as natural solutions to climate change and hence immune to harmful greenhouse gas (GHG) emissions. However, NBCMs, in their daily operations to protect and conserve biodiversity, may result in GHG emissions. These may come as a significant carbon burden. This is the first study based on a literature review to look at the carbon footprint of an entire conservation estate operation and management. South African National Parks (SANParks) aimed to contribute to national targets by reducing their fossil-fuel-generated energy consumption by 2% per year until achieving carbon neutrality. The objectives of this paper were (1) to quantify the SANParks C emissions profile at the organization and individual park level and develop recommendations to sustainably reduce carbon emissions and (2) to suggest alternative scenarios that SANParks could follow to achieve zero energy emissions. The study presented an audit analysis of the emission sources linked to SANParks’ daily activities over a five-year period (2015–2019) using the GHGs protocol corporate accounting and reporting standard methodology. Over the reference period, SANParks emitted an average of 73,732 t of carbon dioxide equivalent (tCO2e) per year. Most emissions came from electricity usage, 40,681 tCO2e (55%), followed by fuel usage for stationary combustion at 26,088 tCO2e (35%), and both account for 90% of SANParks’ total emissions. Results have shown the variation amongst individual parks in GHG emission and intensity ratio among the different parks. Total SANParks emission showed a significant relationship with Scope 2, followed by number of employees, building size, Scope 3, and Scope 1, in order. This work recommends how SANParks estate may reduce their carbon emissions at a national and individual level. SANParks achieved 1% year-on-year energy emissions reduction through its renewable base; however, an ambitious target of 8% would be appropriate for a 1.5 °C future based on the energy scenario planning.

Full textAbstract:
The black soldier fly (BSF) is recognised as a valuable insect for mitigating feed and organic waste management challenges. Thus, concerted efforts are being directed toward the promotion of the BSF. Despite the numerous advantages of BSF larvae, there are several critical environmental aspects, particularly its global warming potential, that need to be considered before large-scale adoption due to the complexity of the insect’s value chain. The direct assessment of greenhouse gas (GHG) and ammonia emissions from BSF larvae biotreatment is crucial for conducting a life cycle assessment (LCA) to evaluate the insect products’ environmental performance. This article reviews the emissions of GHG from BSF larvae bioconversion activities based on different gas sensing techniques while highlighting the factors that influence these emissions. Generally, low gas emissions were reported. However, the influence of various factors influencing emissions remains unclear, especially for nitrous oxide. We also analysed LCA studies on BSFL products while emphasising the uncertainties and variabilities among the studies. The wide variation of impact scores reported in the studies suggests that standardised guidelines should be developed to streamline methodical approaches for impact assessments pertaining to system boundaries, functional units, allocation, and system expansion assumptions. We identified several aspects for future improvements to harmonise studies in order to enhance the comparative assessment of the BSFL products.

Full textAbstract:
The increase in carbon emissions is considered one of the major causes of global warming and climate change. To reduce the potential environmental and economic threat from such greenhouse gas emissions, governments must formulate policies related to carbon emissions. Most economists favor the carbon tax as an approach to reduce greenhouse gas emissions. This market-based approach is expected to inevitably affect enterprises’ operating activities such as production, inventory, and equipment investment. Therefore, in this study, we investigate a production inventory model for deteriorating items under a carbon tax policy and collaborative preservation technology investment from the perspective of supply chain integration. Our main purpose is to determine the optimal production, delivery, ordering, and investment policies for the buyer and vendor that maximize the joint total profit per unit time in consideration of the carbon tax policy. We present several numerical examples to demonstrate the solution procedures, and we conduct sensitivity analyses of the optimal solutions with respect to major parameters for identifying several managerial implications that provide a useful decision tool for the relevant managers. We hope that the study results assist government organizations in selecting a more appropriate carbon emissions policy for the carbon reduction trend.

Full textAbstract:
The paper provides a comparative analysis of economic growth in Estonia, Latvia and Lithuania and discusses differences in development of the main sectors during the period 2000–2016. Based on detailed analysis of energy sector development, the driving factors influencing changes in primary energy consumption in each country and in the Baltic region are discovered. Increase of renewable energy sources (RES) consumption in the Baltic region over this period by 73.6% is emphasized. The paper presents valuable insights from analysis of trends in final energy consumption by sectors of the national economies, branches of the manufacturing sector, and by energy carriers. Long-term relationships between economic growth and final energy consumption are established. An econometric model was applied to predict final energy demand in the Baltic States for the 2020 horizon. It is emphasized that growing activities in the manufacturing and transport sectors will cause increase of final energy demand in all three countries. Based on detailed analysis of greenhouse gas (GHG) emissions trends some positive shifts are shown and the necessity of new policies in the transport sector and agriculture is identified. Changes of emission intensity indicators are examined and a potential for decoupling of carbon dioxide (CO2) emissions from economic growth in Estonia is indicated.

Full textAbstract:
Greenhouse gas (GHG) emissions from reservoirs are responsible for at most 2% of the overall warming effects of human activities. This study aimed at incorporating the GHG emissions of a reservoir (with irrigation/sugar production as its primary purpose), into the carbon footprint of sugar produced from irrigated sugarcane. This study adopts a life-cycle assessment (LCA) approach and encompasses the cradle-to-gate aspect of the international organization of standardization ISO 14040 guidelines. Results show that total carbon footprint of refined sugar could be as high as 5.71 kg CO2-eq/kg sugar, over its entire life cycle, depending on the priority of purposes allocated to a reservoir and sugarcane productivity. Findings also reveal that the dammed river contributes the most to GHG emissions 5.04 kg CO2-eq/kg sugar, followed by the agricultural stage 0.430 kg CO2-eq/kg sugar, the sugar factory 0.227 kg CO2-eq/kg sugar, and lastly the transportation stage 0.065 kg CO2-eq/kg sugar. The sensitivity analysis shows that carbon footprint CF of sugar production is largely influenced by the rate of biomass decomposition in the impounded reservoir over time, followed by the reservoir drawdown due to seasonal climatic fluctuations. Significant amounts of GHG emissions are correlated with the impoundment of reservoirs for water resource development projects, which may account for up to 80% of total GHG emissions to the reservoir’s primary purpose. Sugar production expansion, coupled with allocating more functions to a reservoir, significantly influences the CF of sugar per service purpose. This study is an indicator for policymakers to comprehend and make plans for the growing tradeoffs amongst key functions of reservoirs.

Forest land provides several environmental services and goods with significant implications for different socioeconomic and environmental dimensions. Forestry and its management are determinant activities for sustainable development, specifically in the current context of urgent mitigation of climate change. In this perspective, one objective of this research was to survey the main insights from the literature about the forest and management dimensions put together, highlighting the contributions of these activities to mitigate climate change. Another objective was to explore indicators related to forest management (land, employment, output, and net emissions) in order to obtain a forest sustainability index through factor analysis. As main insights from this study, we can quote that the literature survey pinpoints the most relevant factors framing forest management: soil characteristics, ecology, ecosystems, biodiversity, deforestation, climate change, socioeconomic frameworks, local knowledge, public policies, institutional context, and new technologies. Forest indicators reveal a strong relationship between forest land, employment and output, and a weaker relation with net emissions. We concluded that there is a need for stakeholders to explore and improve the interlinkage with climate change impact, specifically with regard to improving the relationships of forestry greenhouse gas emissions impacts with forest size and output.

Full textAbstract:
Greenhouse gas (GHG) emissions from New Zealand dairy farms are significant, representing nearly 35% of New Zealand’s total agricultural emissions. Although there is an urgent need for New Zealand to reduce agricultural GHG emissions in order to meet its Kyoto Protocol obligations, there are, as yet, few viable options for reducing farming related emissions while maintaining productivity. In addition to GHG emissions, dairy farms are also the source of other emissions, most importantly effluent from milking sheds and feed pads. It has been suggested that anaerobic digestion for biogas and energy production could be used to deal more effectively with dairy effluent while at the same time addressing concerns about farm energy supply. Dairy farms have a high demand for electricity, with a 300-cow farm consuming nearly 40 000 kWh per year. However, because only ~10% of the manure produced by the cows can be collected (e.g. primarily at milking times), a maximum of only ~16 000 kWh of electricity per year can be produced from the effluent alone. This means that anaerobic digestion/electricity generation schemes are currently economic only for farms with more than 1000 cows. A solution for smaller farms is to co-digest the effluent with unutilised pasture sourced on the farm, thereby increasing biogas production and making the system economically viable. A possible source of unutilised grass is the residual pasture left by the cows immediately after grazing. This residual can be substantial in the spring–early summer, when cow numbers (demand) can be less than the pasture growth rates (supply). The cutting of ungrazed grass (topping) is also a useful management tool that has been shown to increase pasture quality and milk production, especially over the late spring–summer. In this paper, we compare the energy and GHG balances of a conventional farm using a lagoon effluent system to one using anaerobic digestion supplemented by unutilised pasture collected by topping to treat effluent and generate electricity. For a hypothetical 300-cow, 100-ha farm, topping all paddocks from 1800 to 1600 kg DM/ha four times per year over the spring–summer would result in 80 tonnes of DM being collected, which when digested to biogas would yield 50 000 kWh (180 GJ) of electricity. This is in addition to the 16 000 kWh from the effluent digestion. About 90 GJ of diesel would be used to carry out the topping, emitting ~0.06 t CO2e/ha. In contrast, the anaerobic/topping system would offset/avoid 0.74 t CO2e/ha of GHG emissions: 0.6 t CO2e/ha of avoided CH4 emissions from the lagoon and 0.14 t CO2e/ha from biogas electricity offsetting grid electricity GHGs. For the average dairy farm, the net reduction in emissions of 0.68 CO2e/ha would equate to nearly 14% of the direct and indirect emissions from farming activities and if implemented on a national scale, could decrease GHG emissions nearly 1.4 million t CO2e or ~10% of New Zealand’s Kyoto Protocol obligations while at the same time better manage dairy farm effluent, enhance on-farm and national energy security and increase milk production through better quality pastures.

Full textAbstract:
Cities are recognized as a major contributor to environmental pressures. Recently, organizational LCA (OLCA) has been found to align well with requirements for city-scale environmental decision support and a novel city-OLCA framework was introduced. City-OLCA combines two relevant aspects: It covers activities beyond public service provision (multi-stakeholder) and emissions beyond greenhouse gases (multi-impact). Its unique approach of acknowledging responsibility levels should help both city-managers and academia in performance tracking and to prioritize mitigation measures. The goal of this work is to test city-OLCA’s feasibility in a first case study with real city data from Vienna. The feasibility was confirmed, and results for 12 impact categories were obtained. As an example, Vienna’s global warming potential, ozone depletion potential, and marine eutrophication potential for 2016 were 14,686 kt CO2 eq., 6796 kg CFC-11 eq., and 310 t N eq., respectively. Our results indicate that current accounting practices may underestimate greenhouse gas emissions of the entire city by up to a factor of 3. This is mainly due to additional activities not covered by conventional standards (food and goods consumption). While the city itself only accounts for 25% of greenhouse gases, 75% are caused by activities beyond public service provision or beyond governmental responsibilities. Based on our results, we encourage city managers to include an organizational based LCA approach in defining reduction strategies. This will reveal environmental blind spots and avoids underestimating environmental burdens, which might lead to setting the wrong focus for mitigation.

Full textAbstract:
This study analyzes the impacts of reducing greenhouse gas (GHG) emissions on the meat and dairy industries. To achieve this goal, the Global Trade Analysis Project (GTAP) database was used in a Computable General Equilibrium (CGE) setting, which allows for the inclusion of carbon taxes and the definition of four alternative environmental policies scenarios using both Global Warming Potential (GWP) and Global Temperature Potential (GTP) as GHG emissions measures. All scenarios analyze the main effects of carbon-based tax economic instruments on the industry and national production, trade, and emissions, comparing the results for different measures of GHG, GWP, and GTP from the Greenhouse Gas Emissions Estimation System (SEEG) sectoral Brazilian emissions database. In contrast with other industries, relatively lower taxes on the meat and dairy industries seem to be the most adequate in terms of cost distribution in the Brazilian economic structure when only the GWP measure is considered. Urban activities and less-methane-intensive industries benefit from climate change policies designed using GWP-based rather than GTP-based carbon taxes. The article also highlights the importance of a gradual introduction of carbon taxes, allowing the most vulnerable industries a transition moment to adopt clean technologies and/or redirect economic activity to less-GHG-emitting segments.

Full textAbstract:
Food systems contribute to up to 37% of global greenhouse gas emissions, and emissions are increasing. Since the emissions vary greatly between different foods, citizens’ choices can make a big difference to climate change. Public engagement events are opportunities to communicate these complex issues: to raise awareness about the impact of citizens’ own food choices on climate change and to generate support for changes in all food system activities, the food environment and food policy. This article summarises findings from our ‘Take a Bite Out of Climate Change’ stand at two UK outreach activities during July 2019. We collected engagement information in three main ways: (1) individuals were invited to complete a qualitative evaluation questionnaire comprising of four questions that gauged the person’s interests, perceptions of food choices and attitudes towards climate change; (2) an online multiple-choice questionnaire asking about eating habits and awareness/concerns; and (3) a token drop voting activity where visitors answered the question: ‘Do you consider greenhouse gases when choosing food?’ Our results indicate whether or not people learnt about the environmental impacts of food (effectiveness), how likely they are to move towards a more climate-friendly diet (behavioural change), and how to gather information more effectively at this type of event.

Full textAbstract:
Nitrogen (N) deposition has increased in recent years and is significantly affected by global change and human activities. Wetlands are atmospheric CH4 and N2O sources and may be affected by changes in N deposition. To reveal the effects of increased N deposition on peatland greenhouse gas exchange, we observed the CH4 and N2O emissions from controlled microcosms collected from a temperate peatland in the Xiaoxing’an mountains, Northeast China. We found that the moss biomass did not change, but the total herb biomass increased by 94% and 181% with 5 and 10-times-higher N deposition, respectively. However, there were no significant changes in CH4 emissions from the microcosms with N addition. The unchanged CH4 emissions were mainly caused by the opposite effect of increased nitrate and ammonium concentrations on soil CH4 production and the increased plant biomass on CH4 emission. We also found that the manipulated microcosms with 5 and 10-times-higher N deposition had 8 and 20-times-higher seasonal average N2O emissions than the control microcosms, respectively. The increased N2O emissions were mainly caused by short-term (≤7 d) pulse emissions after N addition. The pulse N2O emission peaks were up to 1879.7 and 3836.5 μg m−2 h−1 from the microcosms with 5 and 10-times-higher N deposition, respectively. Nitrate and ammonium concentrations increasing in the soil pore water were the reason for the N2O emissions enhanced by N addition. Our results indicate that the increase in N deposition had no effects on the CH4 emissions but increased the N2O emissions of the temperate peatland. Moreover, pulse emissions are very important for evaluating the effect of N addition on N2O emissions.

Full textAbstract:
There has been a call for the construction industry to become more energy efficient in its planning and activities, to reduce greenhouse gas emissions to help combat climate change. The Australian Building Codes Board has implemented ‘Energy Efficiency’ standards through the National Construction Codes to direct the industry towards net zero emissions goals. However, the Board has maintained a focus on operational flows considerations despite this only being a part of the total expenditure in a building lifecycle. Embodied flows, the energy output, and emissions from harvesting, manufacturing, transporting, and manufacturing materials for a building have not been included as a part of the current standards despite their growing share in the outputs of construction. A qualitative document analysis using data from academic articles and industry publications was performed to identify the context in embodied policy development. Findings reveal an abundance of different legislations and initiatives globally, recommending techniques that may effectively achieve embodied flow reductions. The results highlighted that Australia needs to capitalize on the potential reductions in overall energy and emissions from construction. Other regions have provided a strategic and legislative basis for the industry to emulate.

Modeling efforts focused on future greenhouse gas (GHG) emissions from energy and other sectors in California have shown varying capacities to meet the emissions reduction targets established by the state. These efforts have not included potential reductions from changes in ecosystem management, restoration, and conservation. We examine the scale of contributions from selected activities in natural and agricultural lands and assess the degree to which these actions could help the state achieve its 2030 and 2050 climate mitigation goals under alternative implementation scenarios. By 2030, an Ambitious implementation scenario could contribute as much as 147 MMTCO2e or 17.4% of the cumulative reductions needed to meet the state’s 2030 goal, greater than the individual projected contributions of four other economic sectors, including those from the industrial and agricultural sectors. On an annual basis, the Ambitious scenario could result in reductions as high as 17.9 MMTCO2e⋅y−1 or 13.4% of the state’s 2030 reduction goal. Most reductions come from changes in forest management (61% of 2050 projected cumulative reductions under the Ambitious scenario), followed by reforestation (14%), avoided conversion (11%), compost amendments to grasslands (9%), and wetland and grassland restoration (5%). Implementation of a range of land-based emissions reduction activities can materially contribute to one of the most ambitious mitigation targets globally. This study provides a flexible, dynamic framework for estimating the reductions achievable through land conservation, ecological restoration, and changes in management regimes.

Full textAbstract:
Since the industrial revolution, greenhouse gas emissions caused by human activities have posed an unprecedented global challenge to social development and impact on the natural environment. With the growing awareness of environmental protection and the promotion of international cooperation mechanisms, there is a global consensus to control greenhouse gases. In order to avoid irreversible and catastrophic climate change, there is an urgent need for more companies to take action and make credible commitments to combat climate change and carbon reduction goals aligned with the Paris Agreement and the UN Sustainable Development Goals. As one of the largest and most influential international food and beverage companies with a range of well-known brands, PepsiCo has made ambitious commitments to science-based climate goals, including reducing GHG emissions from its direct operations by 75% against the 2015 baseline and reducing GHG emissions across its indirect value chain by 40% by 2030, as well as setting an ambitious new target to achieve net-zero emissions by 2040. PepsiCo has incorporated carbon reduction and climate strategies in all focus areas across its value chain, accelerating its work on broadening the scale of sustainable agriculture and regenerative farming practice; reducing plastic use and increasing the use of recycle and renewable materials as well as adopting low-carbon alternatives; developing efficient and alternative solutions in transportation and distribution; shifting to renewable electricity and fuels in manufacturing and fleet. Up to 2021, PepsiCo has achieved a 23% of the absolute emissions target of reducing Scope 1 and Scope 2 emissions and 7.9% of the absolute emissions target of reducing Scope 3 emissions. This research aims to evaluate the performance of PepsiCo on achieving their carbon reduction targets based on the analysis of the reported carbon estimates and reduction strategies, and also provides future strategic suggestions and guidance by adopting case study analysis. Although PepsiCo has reported great progress in reducing carbon emissions, further efforts are needed to achieve these goals.

Aim. The ratification of the Paris Agreement by Ukraine envisages an increase in the ability to adapt to the negative effects of climate change, as well as promoting low carbon development so as not to endanger food production. At the same time, water resources, on the one hand, are one of the most vulnerable to climate change components of the environment from the state of which the food security of the country depends directly, and on the other hand, the activity of the water management complex causes the emergence of both direct and indirect carbon footprint. Therefore, an indispensable prerequisite for sustainable low carbon development is the assessment of the carbon footprint of the main sectors of Ukraine's water management complex and the identification of priority measures for their decarbonisation and adaptation to expected climate change. Methods. The methodological basis for the assessment of the carbon footprint of the main sectors of the water management complex was the life cycle method (LCA), by which, based on the open data of the National Inventory of Anthropogenic Emissions from Sources and Absorption by Greenhouse Gas Absorbers in Ukraine and the statistical analysis of the results of previous studies. By means of systematic analysis of the main factors of greenhouse gas emission in the water management complex of Ukraine, the priority directions of its decarbonisation and adaptation to climate change were determined. Results. The estimated carbon footprint of Ukraine's water complex in 2017 was estimated to be 5.15 million tons of CO2-equiv, which was 1.6% of the total greenhouse gas emissions in Ukraine in 2017, and taking into account the potential carbon footprint enduse processes can be increased by up to 3%. Due to the deterioration of the water supply networks, an average of 35% of the supplied water is lost in Ukraine. Reducing network leakage by at least 10% will reduce carbon footprint by 30,000 tons of CO2-equiv annually. The priority areas for decarbonisation of the water management complex should be modernization of water supply and water treatment infrastructure, improvement of energy efficiency of pumping equipment and introduction of drip irrigation, and its adaptation to climate change – development of the network of green infrastructure. Conclusions. The low-carbon development of the water management system should include the introduction and coordination of such measures, which, on the one hand, minimize the adverse effects of climate change on water resources and contribute to reducing the carbon footprint of water management activities, and on the other hand, guarantee the achievement of sustainable development goals, in particular for ensuring water and society proper sanitary conditions.

Full textAbstract:
In recent years, the continuous increase of greenhouse gas emissions has led many companies to investigate the activities that have the greatest impact on the environment. Recent studies estimate that around 10% of worldwide CO2 emissions derive from logistical supply chains. The considerable amount of energy required for heating, cooling, and lighting as well as material handling equipment (MHE) in warehouses represents about 20% of the overall logistical costs. The reduction of warehouses’ energy consumption would thus lead to a significant benefit from an environmental point of view. In this context, sustainable strategies allowing the minimization of the cost of energy consumption due to MHE represent a new challenge in warehouse management. Consistent with this purpose, a two-step optimization model based on integer programming is developed in this paper to automatically identify an optimal schedule of the material handling activities of electric mobile MHEs (MMHEs) (i.e., forklifts) in labor-intensive warehouses from profit and sustainability perspectives. The resulting scheduling aims at minimizing the total cost, which is the sum of the penalty cost related to the makespan of the material handling activities and the total electricity cost of charging batteries. The approach ensures that jobs are executed in accordance with priority queuing and that the completion time of battery recharging is minimized. Realistic numerical experiments are conducted to evaluate the effects of integrating the scheduling of electric loads into the scheduling of material handling operations. The obtained results show the effectiveness of the model in identifying the optimal battery-charging schedule for a fleet of electric MMHEs from economic and environmental perspectives simultaneously.

The earth’s average temperature has risen by approximately 1.2 °C since the 1900s. The COP26 resolution aimed to achieve carbon neutrality before 2050, while China has committed a more aggressive timetable to actually achieve the goal. It requires either that activities must not release any greenhouse gases or the emitted greenhouse gases must be offset. The logistics and transport activities contribute a lot to global greenhouse gas emissions on Earth. There are a no. of challenges of the logistics industry that are discussed, then the paradigmatic solutions such as green procurement, green packaging, green transport, and green warehousing, are respectively discussed. The three contemporary concepts of green solutions (circular economy, carbon neutrality and green cocreation) for logistics and transportation are explored. Subsequently, a detailed case study of CN Logistics’ contemporary green solutions is used to illustrate how to tackle the problems and exemplify the best practices to the other 3PL players. There are expected changes on green directives from the HKSAR Government on logistics green compliances. Finally, this paper concludes with an appeal to the industry to start the green journey immediately.

Full textAbstract:
Concerns about the environmental degradation of agricultural activities have increased with trade openness and globalization. In this study, the effects of agricultural product exports on environmental quality are investigated using panel data and instrumental variable regression models for 23 developed and 43 developing countries during 2002–2020. The results indicate that the expansion of agricultural product exports from developing countries has a detrimental effect on the environmental quality of these countries. Total agricultural exports increase pollution due to greenhouse gas emissions in developing countries, while they decrease the N2O emissions in developed countries. Moreover, raw agricultural exports have a positive and significant effect on agricultural pollution emissions in developing countries, while they have a negative and significant effect on N2O emissions in developed countries. In many developing countries, export development is an important policy objective, and agricultural exports are among the most important export sectors. Hence, policymakers need to consider the effects of agricultural product exports on the environment and increase farmers’ awareness about the environmental consequences of agricultural activities. A better understanding of the environmental impacts of agricultural exports from developing countries is highly recommended.

Full textAbstract:
Greenhouse gas (GHG) emissions from human activities are driving climate change and are currently at their highest levels in history. The international community, through the United Nations process, places great emphasis on the decarbonisation of our economies across all sectors. GHG emissions from maritime transport, even if considered the most carbon efficient method of transportation, are projected to increase if no action is taken to decarbonise, and thus pressure has extended to the maritime sector to contribute to the significant GHG emission cuts necessary. The paths by which the maritime sector can contribute to the achievement of the international target of GHG reduction by 2050 are still being determined, but numerous promising options exist. This paper aims to provide an overview of action towards decarbonisation by the international maritime sector, and to assess how Cyprus, an important flag state, can contribute to decarbonisation efforts. A participatory approach was used, through implementation of the EIT Climate-KIC’s Deep Demonstrations methodology, as part of the ‘ Zero-Net Emissions, Resilient Maritime Hubs in Cyprus’ project. The results were used to identify a portfolio of actions related to policy and regulatory development, education and re-skilling, technological development, and operation optimisation, which can support the decarbonisation of the maritime sector in Cyprus.

Full textAbstract:
Global Environment Facility (GEF) support for World Bank sustainable transport activities is described. An overview is presented of current GEF strategy for sustainable transport, which reflects a shift beyond individual technology interventions toward broader objectives, including modal shift, demand management, and land use planning. Ongoing GEF projects that exemplify this shift are reviewed by examining projects in Latin America and Asia whose aim is improving public transport, nonmotorized programs, and institutional capacity related to sustainable transport. The major lessons that can be drawn from these projects, most of which are still at an early stage, is that local authorities are often enthusiastic about getting involved in programs that simultaneously address key transportation concerns in their cities (such as access, safety, congestion, local air quality) and result in less overall energy use and greenhouse gas emissions. Much can be achieved as long as project communications and promotion are addressed and carefully targeted at decision makers and potential beneficiaries.

Full textAbstract:
In agriculture, the wine sector is one of the industries most affected by the sustainability issue. It is responsible for about 0.3% of annual global greenhouse gas emissions from anthropogenic activities. Sustainability in vitiviniculture was firstly linked to vineyard management, where the use of fertilizers, pesticides and heavy metals is a major concern. More recently, the contribution of winemaking, from grape harvest to bottling, has also been considered. Several cellar processes could be improved for reducing the environmental impact of the whole chain, including microbe-driven transformations. This paper reviews the potential of microorganisms and interactions thereof as a natural, environmentally friendly tool to improve the sustainability aspects of winemaking, all along the production chain. The main phases identified as potentially interesting for exploiting microbial activities to lower inputs are: (i) pre-fermentative stages, (ii) alcoholic fermentation, (iii) stage between alcoholic and malolactic fermentation, (iv) malolactic fermentation, (v) stabilization and spoilage risk management, and (vi) by-products and wastewater treatment. The presence of proper yeast or bacterial strains, the management and timing of inoculation of starter cultures, and some appropriate technological modifications that favor selected microbial activities can lead to several positive effects, including (among other) energy savings, reduction of chemical additives such as sulfites, and reuse of certain residues.

Full textAbstract:
The environmental evaluation of the sorption-enhanced water–gas shift (SEWGS) process to be used for the decarbonization of an integrated steel mill through life cycle assessment (LCA) is the subject of the present paper. This work is carried out within the STEPWISE H2020 project (grant agreement No. 640769). LCA calculations were based on material and energy balances derived from experimental activities, modeling activities, and literature data. Wide system boundaries containing various upstream and downstream processes as well as the main integrated steel mill are drawn for the system under study. The environmental indicators of the SEWGS process are compared to another carbon capture and storage (CCS) technology applied to the iron and steel industry (e.g., gas–liquid absorption using MEA). The reduction of greenhouse gas emissions for SEWGS technology is about 40%. For the other impact indicators, there is an increase in the SEWGS technology (in the range of 7.23% to 72.77%), which is mainly due to the sorbent production and transportation processes. Nevertheless, when compared with the post-combustion capture technology, based on gas–liquid absorption, from an environmental point of view, SEWGS performs significantly better, having impact factor values closer to the no-capture integrated steel mill.

Background: Brazil, one of the largest greenhouse gas emitting countries in the world, emitted approximately 2 billion gigatonnes of carbon dioxide (CO2) in 2018. This data is practically the same recorded in the previous year, suggesting that the country’s trajectory of CO2 emissions is stabilized. Methods: This study presents an overview of environmental protection and climate change mitigation policies adopted in Brazil, as well as makes use the multilevel regression modeling technique to investigate the relationship between economic activities variables in relation to CO2 emissions over the years of 1970 to 2018 in all Brazilian states. Results: The results show that the CO2 emissions in the states have the same behavior as the timeline of the change in land use. Conclusions: The public policies and actions by society and the private sector were fundamental to the reduction verified from the year of 2004 that followed until 2010, both in CO2 emissions and in the change in land use and forests. As of this year, there has been a trend towards stability in CO2 emissions. Another important characteristic is that even with a drop in the number of deforestation, the production variables continued to grow, which shows that there may be an increase in production activities, while there is a reduction in deforestation and in CO2 emissions.

Currently, Indonesia has adopted Low Carbon Development (LCD) in its Medium-Term Development Plan (RPJMN) 2020-2024. One of the priority activities is agriculture, which accounts for 12.21% of total greenhouse gas emissions. The agricultural sector is the victim affected by CO2 emissions, such as degradation, shrinkage of agricultural resources, land and water, shifting planting seasons, crop failures, decreased food production due to rising air temperatures, floods, and droughts. Greenhouse gas emissions are predicted to continue to increase along with the increasing demand for food. The purpose of this study is to predict and find an alternative policy framework for low-carbon development in the agricultural sector in Indonesia. This study uses a quantitative and qualitative approach by Artificial Neural Network (ANN), and multicriteria policy (MULTIPOL) analysis. The data were obtained through secondary data in 2014-2018, and the primary data are in-depth interviews, Focus Group Discussions (FGD), and field observations. The results of ANN show that the predictions of provinces that need to adopt low-carbon development in Indonesia are dominated in production centers such as Java Island, so an alternative policy framework using MULTIPOL is needed. Furthermore, this research establishes three scenarios, eight policies, twenty-six actions, and nine evaluative criteria in analyzing the LCD of the agricultural sector. The results indicate that LCD can be conducted by integrating the speed scenario (S2) with a value ranging from 6.3 (policy to increase capacity and quality of human resources) to 18.7 (circular economy). This scenario accommodates policies related to low carbon reduction and agricultural production increase, such as a circular economy, co-benefit adaptation strategies, low carbon technology innovation, and strengthening low carbon networks.
