Journal of Advanced Research in Fluid Mechanics and Thermal Sciences 90, no. 1 (December 25, 2021): 146–53. http://dx.doi.org/10.37934/arfmts.90.1.146153.
Full textAbstract:
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:
In Indonesia, the government invites business actors to jointly reduce greenhouse gas emissions through disclosure of carbon emissions. Disclosure of carbon emissions in Indonesia is still voluntary (voluntary disclosure), so not all companies disclose this information in their reports. The purpose of this article is to assess the impact of factors such as company size, profitability, company growth, environmental committees, and gender diversity on carbon emission disclosure by Indonesia’s manufacturing companies. For the study, the authors selected 16 manufacturing companies listed on the Indonesia Stock Exchange in 2014-2018. The activities of these companies are the subject of study. To measure the extent of the carbon emission disclosure, a checklist is developed based on the measurement sheet provided by the Carbon Disclosure Project (CDP). The CDP is an organisation based in the United Kingdom which supports companies and cities to disclose the environmental impact of major corporations. The main idea of the project is that environmental reporting and risk management should become a business norm in order to ensure sustainable development of the economy. The study results show that company size has an effect on the level of carbon emission disclosure. The bigger is the company – the greater is the pressure that results from its economic activities. Therefore, the government and the public pay more attention to such business entities. It prompts the company to disclose its carbon emissions. At the same time, such factors as profitability, company growth, environmental committee and gender diversity do not affect on carbon emission disclosure. It was found that the level of carbon emission disclosure among Indonesia’s manufacturing companies is very low, and therefore the government and society need to take measures to increase the responsibility of business entities for environmental pollution.

Full textAbstract:
Contemporary industry is beginning to realize the negative impact that they have on the environment in terms of greenhouse gas emissions, destruction of natural habitats, hazardous waste emissions, etc. This new found consciousness has prompted a second look on part of the manufactures at how modern manufacturing practices can be modified so as to be more environmentally friendly. Environmental impact of manufacturing can be minimized in various ways. In this context, management is often called upon to provide active leadership in managing their facilities so as to minimize their environmental impact. Some examples of such activities include green supply chains and design for disassembly. Such activities help to create a closed loop product lifecycle that is required to reduce the amount of raw material used and the amount of waste created by production. Similarly using design for manufacturability principles aid in the minimization of raw material used and waste generated as well. Also, facilities are starting to move away from reactive approaches to environmental issues. They are now using proactive approaches and value seeking approaches where the environmental issues are dealt with before they are created. This paper presents an overview of environment conscious manufacturing practices that seek to minimize the negative environmental impact of manufacturing. Being a literature review, this paper primarily deals with state of the art in current practice pertaining to green manufacturing.

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.

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:
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.

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.

Full textAbstract:
The article emphasizes that very often the main benefits from port projects come from the wider community and the economy, rather than the port industry itself. This is especially true when ports invest in basic infrastructure to provide opportunities for future growth. In addition, a number of investment requirements have joined the ports' requirements to invest in basic infrastructure, as a result of broader societal imperatives, especially in the areas of environmental and energy policy. Ports, in addition to nodes of transport networks, are also sites for a number of activities that may require certain facilities. Based on this broad definition, it is possible to name different types of port infrastructure. There are twelve types of investment in infrastructure. Investments can relate to the construction of new infrastructure, as well as the modernization or reconstruction of existing infrastructure. In general, investments in maritime access benefit all port users, rather than specific segments and specific terminals in the port. Infrastructure investments are needed by seaports to increase their efficiency, address the growing and changing needs of production and supply chains, and adapt to the requirements of sustainable transport in terms of air quality, climate change and biodiversity. Increasing the size and complexity of the fleet. Growth of processing volumes in ports. Long-term transition to decarbonisation of the economy by reducing greenhouse gas emissions, increasing energy efficiency and absorbing low-emission energy sources. Stricter requirements for environmental performance and absorption of alternative fuels. Pressure to increase the modal distribution of more sustainable modes of transport. Pressure towards urbanization of coastal areas, especially in densely populated areas. Strong digitization of almost all parts of the economy, including manufacturing, logistics and transport. Port management models and responsibility for infrastructure investments. Generalized trends lead to investment needs in port infrastructure. Decisions on these investments are made by various entities. This depends on the current model of port management, which differs significantly from one Member State to another. Investments in viable port infrastructure are those that are expected to be of great value (to the benefit of both consumers and society as a whole) in terms of their costs. However, not all viable investments bring the necessary financial return on investment to make them commercially attractive based on the commercial situation. Ports are strategic assets and are defined as "critical infrastructure"). The geopolitical dimension of port development reinforces the argument for public funding mechanisms, as the lack of such mechanisms will accelerate the participation of foreigners in the development of critical port infrastructure. It is necessary to form a platform with mechanisms for providing final support for port development and certain investments.

Full textAbstract:
Tourism is a non-negligible source of greenhouse gas (GHG) emissions. Using South Tyrol (ST) – a small region with a tourism-intensive economy situated in the North of Italy – as a case study, this article discusses a multiregional input–output (MRIO) framework for calculating the direct and indirect emissions embodied in tourist consumption of goods and services at a subnational level. Compared to more standard single-region implementations of the input–output approach, MRIO analysis offers a more accurate depiction of the amount of emissions, that is, embodied in imports, because it acknowledges that in the modern economy supply chains often stretch across multiple borders and that the carbon intensity of production can vary widely from one location to another. Operationalizing the framework has become relatively straightforward since a number of new global MRIO databases have become available in recent years. Furthermore, the analysis could easily be extended to other environmental externalities of tourism, where the model’s capability to explicitly account for spatial spillovers might also be of interest. The modelling exercise at the heart of the article suggests that, over the course of 2010, the process of producing the goods and services consumed by tourists in ST resulted in 1092 kt CO2e of GHGs being emitted into the atmosphere. This is equivalent to average emissions of 191 kg CO2e per overnight visitor, 38 kg CO2e per night or 0.316 kg per euro of tourist expenditure. Direct emissions account for about one-fourth of the total. Almost four-fifths of total emissions appear to be the result of productive activities sited outside ST itself.

Greenhouse gas emissions resulting from municipal solid waste management activities and the associated climate change impacts are getting great attention worldwide. This study investigates greenhouse gas emissions and their distribution during waste collection and transport activities in the Dammam region of Saudi Arabia. Greenhouse gas emissions and associated global warming factors were estimated based on diesel fuel consumption during waste collection and transport activities. Then, waste collection and transport data were used to parameterise a mechanistic collection model that can be used to estimate and predict future fuel consumption and greenhouse gas emissions. For the collection and transport of municipal waste in the study area, the average associated total greenhouse gas emissions were about 24,935 tCO2-eq. Global warming factors for three provinces were estimated as 25.23 kg CO2-eq t-1, 25.04 kg CO2-eq t-1, and 37.15 kg CO2-eq t-1, respectively. Lastly, the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) modelling system was used to estimate the atmospheric dispersion of greenhouse gas emissions. Model results revealed that the maximum daily greenhouse gas concentrations ranged between 0.174 and 97.3 mg m-3, while annual average greenhouse gas concentrations were found to be between 0.012 and 27.7 mg m-3 within the study domain. The highest greenhouse gas concentrations were observed for the regions involving the municipal solid waste collection routes owing to their higher source emission rates.

<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:
This study presents a detailed description of greenhouse gas emissions and reduction strategies adopted by the Australian petroleum industry from 1996–2002. An empirical analysis has been undertaken to examine the impact of such strategies in improving overall industry environmental performance and has ranked them to establish their relative importance in improving corporate ecological-efficiency ratios, a relative measure of environmental performance that compares the production of oil and gas and their environmental impact added. Two major classes of environmental self-regulatory activities identified are greenhouse gas management strategies and greenhouse gas influence strategies; where the latter was found highly inconsistent throughout the study period. We found that investment in emissions abatement activities, environmental collaboration and staff training, implementation of greenhouse policies and environmental reporting act as better greenhouse gas management strategies. In contrast, changing consumer behaviour or demand side management and supporting research and development on projects that reduce greenhouse gas emissions act as better influence strategies. We predict that the two classes of environmental strategies are highly inter-linked and that an optimal combination is needed for achieving better corporate environmental performance. The study provides a basis for the improvement in greenhouse gas management that may help in attaining an effective emission management plan for the industry.

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.

This study analyzes the level and status of greenhouse gas emissions or removals from solid waste management activities in Marabahan Subdistrict, Formulates an action plan for solid waste management that is low in Greenhouse Gas emissions in Marabahan Subdistrict and Projects the level and status of emissions or Greenhouse Gas absorption from waste management solid in Marabahan District until 2030, according to the 2006 IPCC BAU scenario and mitigation actions. The waste sector greenhouse gas emissions inventory results in 2016 reached 5.16 Gg CO2-eq. However, due to improvements in domestic waste management, the 2016 greenhouse gas emissions rate was reduced by 11.1% compared to the BAU scenario. In 2016, waste sector greenhouse gas emissions in the BAU scenario are projected to reach 10.61 Gg CO2-eq, and will continue to grow until 2020 to 11.14 Gg CO2-eq, and in 2030 to 12.64 Gg CO2-eq. In Action Mitigation I waste management is carried out in the community by implementing methane recovery in the waste banks and TPS 3R. In Action Mitigation II, waste management is carried out at the Final Processing Site (TPA) carried out by the local government to handle it. When compared to the BAU scenario, the design of mitigation actions I and II in the context of reducing greenhouse gas emissions resulted in a decrease of 35.2%, 59.5% and 98.3% in 2013, 2020 and 2030.

Full textAbstract:
Besides water vapour, greenhouse gases CO2, CH4, O3 and N2O contribute ~60%, 20%, 10% and 6% to global warming, respectively; minor contribution is made by chlorofluorocarbons and volatile organic compounds (VOC). We present CO2, CH4 and N2O fluxes from natural and relatively unmanaged soil–plant ecosystems (the ecosystems minimally disturbed by direct human or human-induced activities). All natural ecosystems are net sinks for CO2, although tundra and wetlands (including peatlands) are large sources of CH4, whereas significant N2O emissions occur mainly from tropical and temperate forests. Most natural ecosystems decrease net global warming potential (GWP) from –0.03 ± 0.35 t CO2-e ha–1 y–1 (tropical forests) to –0.90 ± 0.42 t CO2-e ha–1 y–1 (temperate forests) and –1.18 ± 0.44 t CO2-e ha–1 y–1 (boreal forests), mostly as CO2 sinks in phytobiomass, microbial biomass and soil C. But net GWP contributions from wetlands are very large, which is primarily due to CH4 emissions. Although the tropical forest system provides a large carbon sink, the negligible capacity of tropical forests to reduce GWP is entirely due to N2O emissions, possibly from rapid N mineralisation under favourable temperature and moisture conditions. It is estimated that the natural ecosystems reduce the net atmospheric greenhouse gas (GHG) emissions by 3.55 ± 0.44 Gt CO2-e y–1 or ~0.5 ppmv CO2-e y–1, hence, the significant role of natural and relatively unmanaged ecosystems in slowing global warming and climate change. However, the impact of increasing N deposition on natural ecosystems is poorly understood, and further understanding is required regarding the use of drainage as a management tool, to reduce CH4 emissions from wetlands and to increase GHG sink from the restoration of degraded lands, including saline and sodic soils. Data on GHG fluxes from natural and relatively unmanaged ecosystems are further compounded by large spatial and temporal heterogeneity, limited sensitivity of current instruments, few and poor global distribution of monitoring sites and limited capacity of models that could integrate GHG fluxes across ecosystems, atmosphere and oceans and include feedbacks from biophysical variables governing these fluxes.

Municipal solid waste (MSW) management has an impact on climate generating greenhouse gases (GHG). To quantify GHG emission from MSW management activities (transportation, composting, recycling and landfill), this study was conducted in the Chittagong City Corporation (CCC). Data were collected about detail MSW management activities of the CCC through conducting a structured questionnaire survey on related personnel with MSW management. To collect data about recycling, another questionnaire survey was conducted on all junkshops near to both dumping sites (Anandabazar and Arefin Nogor) of the CCC. The study found that, composting and recycling of MSW have a positive contribution in reducing GHG emission. Transportation and land-filling of MSW have a contribution in GHG emission. The amount of GHG emission from the existing MSW management system of the CCC is 31,904.68 tons of CO2-eq per month. The life cycle assessment (LCA) study on composting shows that, the reduction of GHG emission is 3.66 tons of CO2-eq per ton of produced compost.

Full textAbstract:
In economies, cleaner technology, increased demand for renewable energy, and more efficient use of natural resources contribute to meeting environmental sustainability targets. The Chinese economy is no exception in its attempts to conserve economic and natural resources via collaborative efforts to embrace cleaner technology, green energy sources, and resource conservation management to preserve resources for future generations. This research examines the influence of cleaner technologies, green energy sources, and natural resource management on reducing greenhouse gas emissions using quarterly data for the Chinese economy from 2000Q1 to 2020Q4. The findings demonstrate that increasing demand for green energy reduces greenhouse gas emissions, hence substantiating the premise of ‘green is clean’ energy development. Additionally, optimum resource usage enhances environmental quality, corroborating the ‘resource cleaner blessing’ hypothesis. The positive link between inward foreign direct investment and greenhouse gas emissions substantiates the ‘pollution haven’ concept, according to which inward foreign direct investment uses unsustainable technology in manufacturing processes, hence degrading air quality indicators. Inadequate access to clean cooking technology and increased population density has a detrimental effect on the country’s environmental sustainability agenda, which must be corrected via sustainable regulations. The causality estimates show the feedback relationship between renewable energy demand (and economic growth) and cleaner technology, between economic growth and green energy (and inbound foreign direct investment), and between population density and economic growth (and green energy). The Impulse Response function estimates suggested that economic growth and population density would likely increase GHG emissions. In contrast, cleaner technology, green energy demand, natural resource management, and inbound foreign direct investment would likely decrease greenhouse gas emissions for the next ten-year time period. The sustainability of the environment and natural resources in China is bolstered by developing cleaner technologies, a greater reliance on renewable energy sources, and better management of natural resources.

Full textAbstract:
Land reclamation activities can, directly and indirectly, impact the environment. Examples of direct effects include alterations in coastal geomorphology, variations in the chemical content of water and changes in biological composition along the littoral zone. The indirect impacts can involve geological changes and increase vulnerability to natural disasters. Reclamation processes also result in greenhouse gas (GHG) emissions from vehicle and machinery fuel use and through the release of carbon stored in vegetation, soils and sediment in mangroves and seagrass ecosystems. Considering the global extent of land reclamation, the scale of these emissions is likely to be of widespread interest. The case of Jakarta Bay provides useful insights that can contribute to the improved environmental management of kindred land development projects in Indonesia and other parts of Asia. More than 5,100 ha of new land mass is planned from the Jakarta Bay reclamation. Preliminary analysis suggests that 30% of the planned area will require more than 150.7 million cubic metres of sand sourced from 8,628 ha of marine quarry area. In this study, we examine the sources of GHG emissions in these activities and the potential opportunities available to reduce them. The audience for this paper includes policymakers, environmental practitioners, city developers and postgraduate scholars dealing with land reclamation or other major infrastructure developments.

Full textAbstract:
Purpose Recent developments in the electricity generation sector of Nigeria necessitated the re-assessment of its contribution to air emission level in the country as information provided by previous inventory is nearly out-of-date. The purpose of this paper is to quantify the carbon dioxide (CO2) emissions generated from existing thermal power plants in the country. Design/methodology/approach Thermal power plants in Nigeria and their installed capacities were identified, and estimation of CO2 emission from each of the plants was carried out using the emission factor method. In addition to the direct emissions generated through the combustion operation of the power plants, indirect emissions resulting from upstream activities such as extraction, production, and transportation of fuels consumed by the thermal power plant was determined using the same method. Findings In total, 40 thermal power plants are currently operational in Nigeria. Additional 18 thermal plants are at different stages of completion. The operational thermal plants have average generation output of 40 percent of their installed capacity and produce 87.3 million metric tonne (mmt)/annum CO2 emissions. In total, 66.9 percent of the estimated emissions are direct emissions, i.e. fuel combustion emissions; the rest are indirect emissions. Additional 67.9 mmt was estimated as expected overall emissions from the thermal power plants under construction. Considering the global warming potential of CO2, proactive measures must be taken to regulate its emissions from the country’s thermal power plants. Originality/value This paper bridged the information gap existing in the emission inventory from the Nigeria electricity sector by providing up-to-date data on the contribution of the sector to greenhouse gas emission level in the country.

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.

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.

Full textAbstract:
The goal to decrease greenhouse gas (GHG) emissions is spurring interest in renewable energy systems from time-varying sources (e.g., photovoltaics, wind) and these can require batteries to help load balancing. However, the batteries themselves add additional GHG emissions to the electricity system in all its life cycle phases. This article begins by investigating the GHG emissions for the manufacturing of two stationary lithium-ion batteries, comparing production in Europe, US and China. Next, we analyze how the installation and operation of these batteries change the GHG emissions of the electricity supply in two pilot sites. Life cycle assessment is used for GHG emissions calculation. The regional comparison on GHG emissions of battery manufacturing shows that primary aluminum, cathode paste and battery cell production are the principal components of the GHG emissions of battery manufacturing. Regional variations are linked mainly to high grid electricity demand and regional changes in the electricity mixes, resulting in base values of 77 kg CO2-eq/kWh to 153 kg CO2-eq/kWh battery capacity. The assessment of two pilot sites shows that the implementation of batteries can lead to GHG emission savings of up to 77%, if their operation enables an increase in renewable energy sources in the electricity system.

Full textAbstract:
The national inventories of greenhouse gas (GHG) emissions, which are periodically prepared by countries that signed the Climate Change Convention, compute emissions from anthropogenic sources among them agricultural activities. The protocols established within the scope of the International Panel on Climate Change (IPCC) make it possible to estimate these emissions. These protocols use standard emission factors that vary according to the characteristics of the monitored activities and only scientific research, published in journals of recognized quality, can establish other local factors. Brazilian researchers carry out experiments to measure GHG emissions from agricultural activities, aiming to calculate specific parameters for the national climatic and management conditions. These field experiments are complex, costly, with a limited number of repetitions and, eventually, high natural variability. Often, these limitations result in the inability of the analysis of variance (ANOVA) to identify differences between treatments. The objective of this work is to present the non-parametric Kolmogorov-Smirnov (KS) test as an alternative to compare the effect of flooded irrigation management on methane (CH4) emission throughout the rice crop cycle. We present a case study in which ANOVA produced non-significant results for the adjustment of the model while the KS identified the emission curves as significantly different. The KS test could be adapted, via the SAS NPAR1WAY routine, to compare events with responses over time, such as methane emissions in flooded rice, resulting in test values and graphs that are easy to understand and interpret.

Abstract This study presents the results of a traffic simulation analysis and emissions (greenhouse gas and noise) assessment comparing pre-pandemic (2019) and post-pandemic (2022) periods. The estimation of road traffic demand is based on conventional data sources and floating car data; next, the traffic simulation procedure was performed providing road network traffic volumes, which are the input for the emission models. The diffusion of teleworking, e-commerce, as well as the digitization of many processes, services and activities, lead to a significant change in urban mobility. Results show a significant though still not complete resumption of commuters travel activity (−10% compared to pre-pandemic period) in the morning peak-hour. This translates into an 11% reduction of greenhouse gas emissions and a 0.1% increase in noise emissions.

Households with all their activities produce waste which can be a source of GHG emissions if not managed properly. Reducing waste from its source is one of the ways to reduce GHG emissions. In Bandung Regency, one of the ways to reduce household waste is by running the Waste Bank program. Research is needed to find out how much the reduction of GHG emissions from waste management in the Waste Bank. This study used a combination of quantitative and qualitative methods with descriptive analysis including IPCC method to estimate GHG emission reductions from waste management and in-depth interview with the operators in one of the Master Waste Banks (Bank Sampah Induk) in Bandung Regency, Y Waste Bank. The results showed that the potential GHG emission reductions from Y Waste Bank reached 0.016 Gg CH4 or equivalent to 401.273 tons of CO2eq, reducing GHG emissions from total household waste in Bandung Regency by 0.0007 %. Program and technology innovations and also assistance for customers or fostered groups are expected to be able to increase the quantity of waste managed at the Y Waste Bank up to the household level so that it can give higher contribution in reducing GHG emissions in Bandung Regency.

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

For identifying opportunities for reducing greenhouse gas (GHG) emissions from milk production in Ontario, this study analyzed GHG intensity of milk [kg CO2 equivalents kg−1 fat and protein corrected milk (FPCM)] in 2011 compared with 1991 considering cow and crop productivity improvements and management changes over this period. It also assessed within-province variability in GHG intensity of milk in 2011 using county-level data related to milk production. After allocating whole-farm GHG emissions between milk and meat using an allocation factor calculated according to the International Dairy Federation equation, GHG intensity of Ontario milk was 1.03 kgCO2eq kg−1 FPCM in 2011, 22% lower than that in 1991 (1.32 kg CO2eq kg−1 FPCM). Greenhouse gas sources directly associated with dairy cattle decreased less (21 and 14% for enteric fermentation and manure management, respectively) than sources associated with feed crop production (30 to 34% for emissions related to N inputs and farm-field work). Proportions of GHG contributed from different life cycle activities did not change, with enteric fermentation contributing 46%, feed crop production 34%, manure management 18% and milking and related activities 2%. Within province, GHG intensity varied from 0.89 to 1.36 kg CO2eq kg−1 FPCM, a variation inversely correlated with milk productivity per cow (kg FPCM sold cow−1 year−1). The existence of a wide variation is strong indication for potential further reductions in GHG intensity of Ontario milk through the identification of practices associated with high efficiency.

Carbon fibers (CFs) are promising lightweight materials to reduce vehicle fuel consumption. However, the most widely used polyacrylonitrile (PAN)-based CF production process consumes a considerable amount of energy. A novel production process for CFs from aromatic polymers (APs) is proposed as an alternative. In this study, the greenhouse gas (GHG) emissions from PAN-based CFs, from APs using the classical benzidine method, and from APs using the coupling method on a cradle-to-gate basis, were analyzed. The results indicate that the AP CFs with the classical benzidine method generated 11% fewer GHG emissions compared with the conventional PAN CFs. Emissions were further reduced by 42% using a large-tow production process. As the classical benzidine method for manufacturing CFs from APs uses a monomer synthesized via benzidine, which is carcinogenic, we examined a different synthetic route using the coupling method for monomer synthesis to avoid the benzidine intermediate. The GHG emissions from the AP CFs manufactured by the coupling method showed a 51% increase compared with PAN-based CFs, indicating a trade-off between GHG emissions and carcinogenicity. However, with proper chemical management, the classical method of CF manufacturing from APs via benzidine showed reduced GHG 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 liability of multinational entities that have caused greenhouse gas emissions through their extraction activities in the fossil fuel industry has pushed climate change on to the international agenda. Those corporations now face challenges from litigants who have initiated negligence or nuisance actions for breach of duty of care. Suits against individual corporations are now possible due to the development of attribution science that can register the extent of each liability. Litigants from third-world countries have to satisfy locus standi in bringing claims which is difficult to establish in some jurisdictions. For example, in Lliuya v. RWE, (Az. 2 O 285/15, OLG Hamm) 24/1/2017, a South American farmer brought a claim in Germany against RWE-AG, Germany’s largest electricity producer, to challenge the effects of greenhouse gas emissions from its plant in Peru. This paper asks: Is it possible for foreign litigants to bring a private tort action against the defendant corporation that has allowed greenhouse gas emissions, in that corporation’s domestic courts, and to surmount the obstacle of locus standi? It concludes that it is possible for litigants from developing countries to litigate effectively because the foreign courts’ statutory protections, such as the doctrine of separation of powers or political rights doctrine can be overcome if climate litigation is viewed as a human rights matter. The prospects of success of litigants has increased by the impact of event attribution science that can quantify the extent of private actor liability in climate change.

Abstract In Brazil beef cattle production is one of the most important activities in the agricultural sector and has an important impact on environmental and resources consumption. In this study assessed greenhouses gases (GHG) impacts from on farms representative productive system and the possible improvements of the production chain. Primary data from animal production index and feeding were collected from 17 farms, which covers 300.000 animals and 220.000 hectares. Emissions of methane, nitrous oxide and carbon dioxide were made using intergovernmental panel on climate change (IPCC) guidelines for national inventories. The GHG inventory included emissions from animals, feeds and operations for animal operation from “cradle to farm gate”. Emissions of each farm were converted to carbon dioxide equivalent (CO2eq) and divided by carcass production. Regression analysis between carbon dioxide equivalent and productive index was run to identify possible hotspot of GHG emissions. A large variation between farms were observed. The GHG yield ranged from 8.63 kg to 50.88 CO2eq kg carcass-1. The productive index age of slaughtering (P < 0.0001), average daily gain (P < 0.0001) and productivity (P = 0.058) per area were positive correlated to GHG yield. While no correlation was found with stocking rate (P = 0.21). Improvements of the production chain could be realized by accurate animal management strategies that reduce the age of slaughtering (feeding and genetic improvements) and gain individual or per area using strategic animal supplementation and pasture management, in order to obtains reduction of GHG emissions of beef cattle.

The findings indicate that Polish enterprises most frequently performed activities that involved using or improvement of technologies to reduce air emissions and implementation of monitoring and emissions measurement systems. The implemented or improved technologies mostly focused on limiting hard coal usage and replacing it with other energy sources, e.g., liquid gas, earth gas, or renewable energy sources. Analyzed enterprises also performed activities with the purpose of process containment, improvement of offered products, or reducing transport-related emissions.

Abstract. We present results from the FAOSTAT emissions shares database, covering emissions from agri-food systems and their shares to total anthropogenic emissions for 196 countries and 40 territories for the period 1990–2019. We find that in 2019, global agri-food system emissions were 16.5 (95 %; CI range: 11–22) billion metric tonnes (Gt CO2 eq. yr−1), corresponding to 31 % (range: 19 %–43 %) of total anthropogenic emissions. Of the agri-food system total, global emissions within the farm gate – from crop and livestock production processes including on-farm energy use – were 7.2 Gt CO2 eq. yr−1; emissions from land use change, due to deforestation and peatland degradation, were 3.5 Gt CO2 eq. yr−1; and emissions from pre- and post-production processes – manufacturing of fertilizers, food processing, packaging, transport, retail, household consumption and food waste disposal – were 5.8 Gt CO2 eq. yr−1. Over the study period 1990–2019, agri-food system emissions increased in total by 17 %, largely driven by a doubling of emissions from pre- and post-production processes. Conversely, the FAOSTAT data show that since 1990 land use emissions decreased by 25 %, while emissions within the farm gate increased 9 %. In 2019, in terms of individual greenhouse gases (GHGs), pre- and post-production processes emitted the most CO2 (3.9 Gt CO2 yr−1), preceding land use change (3.3 Gt CO2 yr−1) and farm gate (1.2 Gt CO2 yr−1) emissions. Conversely, farm gate activities were by far the major emitter of methane (140 Mt CH4 yr−1) and of nitrous oxide (7.8 Mt N2O yr−1). Pre- and post-production processes were also significant emitters of methane (49 Mt CH4 yr−1), mostly generated from the decay of solid food waste in landfills and open dumps. One key trend over the 30-year period since 1990 highlighted by our analysis is the increasingly important role of food-related emissions generated outside of agricultural land, in pre- and post-production processes along the agri-food system, at global, regional and national scales. In fact, our data show that by 2019, pre- and post-production processes had overtaken farm gate processes to become the largest GHG component of agri-food system emissions in Annex I parties (2.2 Gt CO2 eq. yr−1). They also more than doubled in non-Annex I parties (to 3.5 Gt CO2 eq. yr−1), becoming larger than emissions from land use change. By 2019 food supply chains had become the largest agri-food system component in China (1100 Mt CO2 eq. yr−1), the USA (700 Mt CO2 eq. yr−1) and the EU-27 (600 Mt CO2 eq. yr−1). This has important repercussions for food-relevant national mitigation strategies, considering that until recently these have focused mainly on reductions of non-CO2 gases within the farm gate and on CO2 mitigation from land use change.

Abstract Green logistics is the part of the activities of an enterprise aimed at measuring and minimizing the impact of logistics activities on the environment. Such actions are dictated by the possibility of achieving a competitive advantage in the market, because clients require it. Transport is a particularly important area with a huge impact on the environment, because it is identified as the fastest growing source of greenhouse gas emissions. Green transport is low-emission and ecological travelling mode. The goals of green transport are not only to reduce greenhouse gas emissions, air pollution, noise and space use, but also to reduce poverty and promote economic growth. Transport is considered green when it supports environmental sustainability, but also supports the other two pillars of sustainable development, i.e. economic and social. This paper discusses the application of the concept of "green" logistics and "green" technologies in transport in the transportation process. The modern requirements for transport in the field of environmental safety and compliance with environmental requirements both on the part of customers and on the part of states are considered.

Full textAbstract:
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.

Full textAbstract:
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.

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.
