SUMMARYThe aim of the present study was to compare the effect of changing a range of biological traits on farm profit and greenhouse gas (GHG) emissions (expressed as carbon dioxide equivalent, CO2-eq.) in the UK dairy cow population. A Markov chain approach was used to describe the steady-state herd structure of the average milk-recorded UK dairy herd, as well as to estimate the CO2-eq. emissions per cow, and per kilogram of milk solids (MS). Effects of changing each herd production and fitness trait by one unit (e.g. 1 kg milk; 1% mastitis incidence) were assessed, with derived values for change in profit (economic values) being used in a multi-trait selection index. Of the traits studied, an increase in survival and reductions in milk volume, live weight, residual feed intake, somatic cell count, mastitis incidence, lameness incidence and calving interval were traits that would be both profitable and reduce CO2-eq. emissions per cow and per kg MS of a dairy herd. A multi-trait selection index was used to estimate the annual response in production and fitness traits and the economic response, with an estimate of annual profit per cow from selection on multiple traits. Milk volume, milk fat and protein yield, live weight, survival and dry matter intake were estimated to increase each year and body condition score, residual feed intake, somatic cell count, mastitis incidence, lameness incidence and calving interval were estimated to decrease, with selection on these traits estimated to result in an annual increase of 1% per year in GHG emissions per cow, but a reduction of 0·9% per unit product. Improved efficiencies of production associated with a reduction in milk volume (and increasing fat and protein content), live weight and feed intake (gross and metabolic efficiency, respectively), and increase in health, fertility and overall survival will increase farm annual profit of UK dairy systems and reduce their environmental impact.

Abstract. Cumulative emissions budgets and net-zero emission target dates are often used to frame climate negotiations (Frame et al., 2014; Millar et al., 2016; Van Vuuren et al., 2016; Rogelj et al., 2015b; Matthews et al., 2012). However, their utility for near-term policy decisions is confounded by uncertainties in future negative emissions capacity (Fuss et al., 2014; Smith et al., 2016; Larkin et al., 2018; Anderson and Peters, 2016), in the role of non-CO2 forcers (MacDougall et al., 2015) and in the long-term Earth system response to forcing (Rugenstein et al., 2019; Knutti et al., 2017; Armour, 2017). Such uncertainties may impact the utility of an absolute carbon budget if peak temperatures occur significantly after net-zero emissions are achieved, the likelihood of which is shown here to be conditional on prior assumptions about the long-term dynamics of the Earth system. In the context of these uncertainties, we show that the necessity and scope for negative emissions deployment later in the century can be conditioned on near-term emissions, providing support for a scenario framework which focuses on emissions reductions rather than absolute budgets (Rogelj et al., 2019b).

Purpose – The purpose of this paper is to investigate the vital determinants on the extent of corporate social responsibility (CSR) disclosure in a US context. The selected variables are CEO duality, the presence of women in the board, greenhouse gas (GHG) emissions, emission reduction initiatives, company's risk premium, financial leverage and industry's profile. Design/methodology/approach – The environmental, social and governance (ESG) disclosure score is used as a proxy for the extent of CSR disclosure calculated by Bloomberg. The influence of plausible variables on the ESG disclosure score and its sub-categories was examined by using the least squares dummy variable model (LSDV) incorporating 100 companies listed on Standard & Poor's 500 Index for the period 2009-2012. Findings – The results show that the emission reduction initiatives and GHG emissions influence positively the extent of ESG score. In addition, slight differences exist concerning the determinants of different types of disclosures. Furthermore, it is illustrated that a company's industrial profile seems to have differences among the extent of the different types of disclosure. Research limitations/implications – The sample of companies is based on the US companies incorporating only large-sized ones. Originality/value – The study extends previous studies with the inclusion of both traditional and innovative determinants of the CSR disclosure in USA taking into account four years of corporate data. A third party rating approach was adopted in order to calculate the extent of CSR disclosure. Finally, both the shareholders’ and the investors’ attitudes in relation to CSR disclosure are presented.

The emerging carbon economy will have a major impact on grazing businesses because of significant livestock methane and land-use change emissions. Livestock methane emissions alone account for ~11% of Australia’s reported greenhouse gas emissions. Grazing businesses need to develop an understanding of their greenhouse gas impact and be able to assess the impact of alternative management options. This paper attempts to generate a greenhouse gas budget for two scenarios using a spread sheet model. The first scenario was based on one land-type ‘20-year-old brigalow regrowth’ in the brigalow bioregion of southern-central Queensland. The 50 year analysis demonstrated the substantially different greenhouse gas outcomes and livestock carrying capacity for three alternative regrowth management options: retain regrowth (sequester 71.5 t carbon dioxide equivalents per hectare, CO2-e/ha), clear all regrowth (emit 42.8 t CO2-e/ha) and clear regrowth strips (emit 5.8 t CO2-e/ha). The second scenario was based on a ‘remnant eucalypt savanna-woodland’ land type in the Einasleigh Uplands bioregion of north Queensland. The four alternative vegetation management options were: retain current woodland structure (emit 7.4 t CO2-e/ha), allow woodland to thicken increasing tree basal area (sequester 20.7 t CO2-e/ha), thin trees less than 10 cm diameter (emit 8.9 t CO2-e/ha), and thin trees <20 cm diameter (emit 12.4 t CO2-e/ha). Significant assumptions were required to complete the budgets due to gaps in current knowledge on the response of woody vegetation, soil carbon and non-CO2 soil emissions to management options and land-type at the property scale. The analyses indicate that there is scope for grazing businesses to choose alternative management options to influence their greenhouse gas budget. However, a key assumption is that accumulation of carbon or avoidance of emissions somewhere on a grazing business (e.g. in woody vegetation or soil) will be recognised as an offset for emissions elsewhere in the business (e.g. livestock methane). This issue will be a challenge for livestock industries and policy makers to work through in the coming years.

This article takes advantage of the pilot Emissions Trading Scheme (ETS) project to estimate the causal impact of the ETS on CO2 abatement in China. The CO2 emissions and CO2 intensities of each province are calculated by using the fossil fuel data of 30 provincial administration regions from 2006 to 2016. Then difference in difference (DiD) models and propensity score matching (PSM) with panel data are applied to estimate the causal impact of the pilot ETS project. Results show that the pilot regions reduce their CO2 emissions and intensities more than the non-pilot regions under the pilot ETS project. The pilot ETS project significantly induced 12% decreases in the nominal CO2 intensity and 7.6% decrease in the real CO2 intensity, after controlling for regional heterogeneity, but its reduction effects on CO2 emissions are insignificant. Decreasing the proportion of coal to total energy consumption may be the main channel of the pilot ETS project inducing CO2 abatement. The estimated results for control variables indicate that upgrading industrial structures, attracting FDI, and purifying the export structure have significant effects on CO2 abatement.

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.

This paper investigates the impact of a plausible set of determinants, namely, greenhouse gas (GHG) emissions, Dow Jones Sustainability Index (DJSI), anti-bribery policy, the industry’s profile and the company’s size on the extent of CSR disclosure in the United States (US). The Environmental, Social and Governance (ESG) disclosure score is used as a proxy for the extent of CSR disclosure calculated by Bloomberg, incorporating different - in terms of importance - disclosure items. The relationship between the extent of CSR disclosure and its determinants was examined using multiple linear regression analysis incorporating 133 companies listed in S&P Composite 1500 Index for the year 2011. The results illustrate that the company’s size, GHG emissions, DJSI and anti-bribery policy are significantly positively associated with the extent of CSR disclosure. In addition, there are significant differences among the industries’ profile concerning the extent of CSR disclosure. The results cannot be generalized because the sample is based on US listed companies for the year 2011. This study presents initial empirical data investigating different types of disclosures and determinants which extend the scope of previous studies

Gresik urban area is dominated by industrial, housing, trade and services activities. The growth of activities contributes to the land use change from green open spaces into built-up areas. The impact of land use change influence the level of air pollution and CO2 gas emission in Gresik urban area. The previous study briefly shows that this urban area produces 50.37% of the total CO2 gas emissions. The production of CO2 gas emissions should be controlled to reduce the impact of climate change in urban areas such as increasing urban temperature, hydrological cycle anomaly, drought, land degradation and other social and environmental issues. The green open space can recycle the CO2 gas emissions and can increase the absorption capacity of the CO2 gas emissions (bio-capacity). The land cover change for built-up area potentially reduces the absorption of CO2 gas emissions in Gresik urban area. Therefore the identification of the land cover change on CO2 emission absorption becomes an objective of this study. The preliminary study can formulate the strategic steps in the development of Gresik urban area that supports urban greenery and adaptive effort to respond the climate change. The study is conducted in two steps. The first step is to analysis the land cover change based on the Landsat satellite imagery analysis. The second step is to measure the dynamic change of the region's ability(bio-capacity) to absorb CO2 emissions by using ecological footprint analysis. The results show that Gresik urban area has a high development of developed land to the North area, Manyar Sub District. The growth of the developed land is more converting the fishpond land. The green areas in this regiontend to be influenced by farming activities which also convert into fishpond land. Bio-capacity of CO2 gas emission absorption increases from 2003 of 3.548 gha to 5.656 gha but the comparison between bio-capacity of CO2 gas emission absorption and developed land shows the declining tendency in each year. In 2003, the comparison score is 1.59 gha/ha of developed land. In 2014, the score is declining into 1.48 gha/ha or developed land.

Cities are one of the key contributors to the environment and sustainability. This study aims to quantify citywide energy-related CO2 emissions and assess the sustainability feasibility of implementing climate change mitigation policies in Chiang Mai, Thailand. By employing the GPC method, it was found that the average energy-related CO2 emission in Chiang Mai from 2015 to 2019 was 2,146,060 tCO2eq. Residences, industries (i.e., food preservation industries), and commercial and governmental buildings were the top three energy consumption-related GHG emitters. According to the Analytical Hierarchy Process (AHP), in terms of mitigation measures, LED lighting presented the highest score (0.380), followed by improving air conditioning efficiency (0.278), and the use of energy-efficient appliances (0.203). Energy-efficient technologies would be more feasible than the development of renewable energy technologies to lower CO2 emissions. In terms of sustainability, political, technical, and economic feasibility criteria presented the highest AHP score (0.789), followed by human and social dimensions criteria (0.129), and environmental performance criteria (0.073). Policy possibility had the highest AHP score, while direct contribution to climate benefits as GHG reduction presented the lowest score. The integration of climate mitigation opportunities into national policies, the green industry scheme, and promoting residents’ self-determined motivation are urgently recommended.

Environmental sustainability continues to attract global interest, especially due to the issue of climate change. The agri-food sector is considered a major contributor to climate change as processes and activities within the sector can negatively impact the environment. The recent changing dietary pattern towards increased vegetable consumption implies a consequent increase in production to meet demand. This study assessed the environmental performance of 1 kg of spinach/FU (Functional Unit) cultivated by different producers in Italy under integrated and organic farming systems. The life cycle assessment was used following the CML_IA impact assessment method. The data used was mainly primary, related to 2019/2020 (harvest period), and representative of the cultivation systems of central and southern Italy. From the results obtained, impact scores for central Italy were higher (e.g., for global warming 0.56 and 0.47 kg CO2 eq. for central and southern respectively). There was high variability among the scores obtained. However, no statistically significant differences were observed at a confidence level of 95% (p < 0.05). Integrated farming was also more impacting than organic for most categories (e.g., for global warming 0.20 kg CO2 eq. for integrated and 0.075 kg CO2 eq. for organic) in Cerignola, Puglia region. Emissions from fertilizer, pesticide, tillage, and combine harvesting were major contributors to impact shares. The results of this study will be helpful to ensure sustainable spinach production and consumption.

This paper evaluates the evolution of eco-efficiency for the 27 European Union (EU) countries over the period 2008–2018, provided the traditional high concerns of the EU concerning the economic growth-environmental performance relationship. The EU has triggered several initiatives and regulations regarding environmental protection over the years, but as well the Sustainable Development Goals demand it. Under this setting, we conduct a two-stage analysis, which computes eco-efficiency scores in the first stage for each of the pairs EU 27-year, through the nonparametric method data envelopment analysis (DEA), considering the ratio GDP per capita and greenhouse gas emissions (GHG). In the second stage, scores are used as a dependent variable in the proposed fractional regression model (FRM), whose determinants considered were eight pollutants (three greenhouse gases and five atmospheric pollutants). CO2/area and N2O/area effects are negative and significant, improving the eco-efficiency of the EU 27 countries. When the efficient European countries are excluded from the estimations, the results evidence that CO2/area and CH4/area decrease the DEA score. The country with the lowest GHG emissions and pollutant gases was Ireland, being the country within the considered period that mostly reduced emissions, particularly SOx and PM10, increasing its score.

During the past decades, environmental related taxes, energy, and carbon taxes has been recommended by environmental scientists as a policy tool to mitigate pollutant emissions in developed and developing economies. Among developed nations, Denmark, Finland, Sweden, the Netherlands, and Norway were the first regions to adopt a tax on carbon dioxide (CO2) emissions and research into the impacts of carbon tax on carbon emissions bring significant implications. The prime objective and goal of this work is to explore the role of carbon tax reforms for environmental quality in European economies. This is probably the first study to conduct a comparative study in European context for carbon-tax implementation and non-implementation policies. To this end, the present study reports new conclusions and implications regarding the effectiveness of environmental regulations and policies for climate change and sustainability. In the present study, the authors exhaustively explore the impacts of the carbon-tax on the mitigation of CO2 emissions. Using the propensity score matching method, the results of the estimation of the different matching methods allow us to observe a positive and significant impact of the adoption of the carbon-tax on stimulating the reduction of carbon emissions.

Carbon dioxide (CO2) can be stored in geological formations beneath the UK continental shelf (UKCS) as a greenhouse gas mitigation option. It can be trapped in subsurface reservoirs in structural or stratigraphic traps beneath cap rocks, as a residual CO2 saturation in pore spaces along the CO2 migration path within the reservoir rock, by dissolution into the native pore fluid (most commonly brine), by reaction of acidified groundwater with mineral components of the reservoir rock, or by adsorption onto surfaces within the reservoir rock, e.g. onto the carbonaceous macerals that are the principal components of coal. Estimates of the CO2 storage capacity of oil and gas fields on the UKCS suggest that they could store between 1200 and 3500×106 t of CO2 and up to 6100×106 t CO2, respectively. Estimating the regional CO2 storage potential of saline water-bearing sedimentary rocks is resource-intensive and no UK estimates have yet taken into account all the factors that should be considered. Existing studies estimate the pore volume and the likely CO2 saturation in the closed structures in a potential reservoir formation but do not take account of the potentially limiting regional pressure rise likely to occur as a result of the very large-scale CO2 injection that would be necessary to make an impact on national emissions. There is undoubtedly great storage potential in the saline water-bearing reservoir rocks of the basins around the UK, but the real challenge for studies of aquifer CO2 storage capacity in the UK is perhaps not to estimate the total theoretical CO2 storage capacity, as this is not a particularly meaningful number. Rather it is to thoroughly investigate selected reservoirs perceived to have good storage potential to a standard where there is scientific consensus that the resulting storage capacity estimates are realistic. This will allow it to be considered as closer to the status of a reserve rather than a resource and will help define the scope for CO2 capture and storage in the UK.

China’s rapid economic growth is accompanied by increasing energy consumption and severe environmental problems. As sustainable development can only be achieved by reducing energy intensity, new energy and renewable energy investment, as well as improving traditional energy efficiency, is becoming increasingly important. However, past energy efficiency assessments using data envelopment analysis (DEA) models mostly focused on radial and non-radial DEA model analyses. However, traditional radial DEA models ignore non-radial slacks when evaluating efficiency values, and non-radial DEA models ignore the same proportionality as radial DEA when evaluating efficiency value slacks. To balance the radial and non-radial model characteristics and consider undesirable output, this study combines a modified Epsilou-based measure (EBM) DEA and undesirable output and proposes a modified undesirable EBM DEA model to analyze the efficiency of China’s new and traditional energy sources. The empirical results found that (1) most new energy investment in most municipalities/provinces rapidly grew from 2013 to 2016; (2) as the annual efficiency score was only 1 in Beijing, Inner Mongolia, Shanghai, and Tianjin, the other 26 municipalities/provinces need significant improvements; (3) traditional energy efficiency scores were higher than new energy efficiency; and (4) NO2 efficiencies are slightly better than CO2 and SO2 efficiencies.

This study compares the environmental impacts of petrol, diesel, natural gas, and electric vehicles using a process-based attributional life cycle assessment (LCA) and the ReCiPe characterization method that captures 18 impact categories and the single score endpoints. Unlike common practice, we derive the cradle-to-grave inventories from an originally combustion engine VW Caddy that was disassembled and electrified in our laboratory, and its energy consumption was measured on the road. Ecoivent 2.2 and 3.0 emission inventories were contrasted exhibiting basically insignificant impact deviations. Ecoinvent 3.0 emission inventory for the diesel car was additionally updated with recent real-world close emission values and revealed strong increases over four midpoint impact categories, when matched with the standard Ecoinvent 3.0 emission inventory. Producing batteries with photovoltaic electricity instead of Chinese coal-based electricity decreases climate impacts of battery production by 69%. Break-even mileages for the electric VW Caddy to pass the combustion engine models under various conditions in terms of climate change impact ranged from 17,000 to 310,000 km. Break-even mileages, when contrasting the VW Caddy and a mini car (SMART), which was as well electrified, did not show systematic differences. Also, CO2-eq emissions in terms of passenger kilometers travelled (54–158 g CO2-eq/PKT) are fairly similar based on 1 person travelling in the mini car and 1.57 persons in the mid-sized car (VW Caddy). Additionally, under optimized conditions (battery production and use phase utilizing renewable electricity), the two electric cars can compete well in terms of CO2-eq emissions per passenger kilometer with other traffic modes (diesel bus, coach, trains) over lifetime. Only electric buses were found to have lower life cycle carbon emissions (27–52 g CO2-eq/PKT) than the two electric passenger cars.

This paper develops a bottom-up approach in the scope of a multi-objective linear programming model (MOLP) based on Input-Output (I-O) analysis to account for investment options aimed at improving the thermal properties of building envelope (e.g., the insulation of external walls and roof, and the replacement of window frames and window glazing). This methodological framework aims at assessing the trade-offs between the overall employment, GDP and energy savings associated with the building sector (residential, private services and public services). Distinct impacts, namely on direct and indirect employment generation, environment (CO2 emissions), energy security supply (energy imports and renewable energy production) and other relevant economic indicators are also analysed. Different sets of input parameters for the economic context and the environmental impacts have been defined as interval coefficients to account for uncertainty. Robust solutions are then obtained by considering the minimisation of the worst possible deviation of the interval objective functions to the corresponding interval ideal solutions.

Due to growing concerns of global warming, reducing carbon emissions has become one of the major tasks for developing countries to meet the national demand for energy policies. The objective of this study is to measure the energy consumption, carbon emission and economic-environmental efficiency in terms of the environmental performance of the top 20 industrial countries by employing a data envelopment analysis (DEA) model from 2013 to 2017. This study used the trilemma of energy efficiency, CO2 emission efficiency, and environmental efficiency, and also the contribution included the quantitative analysis of 20 industrial countries The results show that the energy efficiency of Australia, China, Japan, Saudi Arabia, and Poland are the best performing countries, whereas Mexico, Indonesia, Russia, and Brazil are identified as least efficient among all 20 countries. Furthermore, Russia’s energy intensity has a maximum score while Poland has a minimum score. Additionally, in the case of CO2 emission efficiency, Brazil, France, and Saudi Arabia are considered as efficient while nine country’s scores were less than 0.5. The results show that most countries exhibit higher performance in economic efficiency than environmental efficiency. The study provides valuable information for energy policy-makers.

AbstractObjective:To identify differences in dietary quality, dietary greenhouse gas (GHG) emissions and food consumption over 20 years in a Dutch cohort.Design:Participants (n 8932) filled out an FFQ in 1993–1997 and in 2015. The Dutch Healthy Diet index 2015 (DHD15-index) score, GHG emissions and consumption of food groups (g/4184 kJ (1000 kcal)) were compared between the time points with paired t tests.Setting:The Netherlands.Participants:European Prospective Investigation into Cancer and Nutrition – Netherlands (EPIC-NL) cohort, aged 18–65 years at baseline.Results:Total energy intake decreased by –678 (95 % CI –4908, 3377) kJ/d (–162 (95 % CI –1173, 807) kcal/d) for men and –372 (95 % CI –3820, 3130) kJ/d (–89 (95 % CI –913, 748) kcal/d) for women. DHD15-index scores increased by 11 % (from 64·8 to 71·9 points) and 13 % (from 65·2 to 73·6 points) in men and women, respectively (P < 0·0001), mainly due to an increased (shell)fish and nuts/seeds/nut paste consumption. After energy intake adjustment, dietary-related GHG emissions increased by 5 % in men (2·48–2·61 kg CO2-eq/4184 kJ (1000 kcal), P < 0·0001) and were similar in women (0·4 %, 2·70–2·71 kg CO2-eq/4184 kJ (1000 kcal), P = 0·3930) due to the increased consumption of (shell)fish, nuts/seeds/nut paste, poultry and higher GHG-intensive red meats such as beef.Conclusions:This Dutch cohort analyses showed more healthy diets without mitigated GHG emissions over a 20-year period, at similar energy intakes. Higher consumption of (shell)fish and poultry was not yet at the expense of red and processed meat. Lower consumption of animal-based foods is needed to achieve healthier as well as environmentally friendly diets.

The Czech Republic is gradually shifting toward a low-carbon economy. The transition process requires measures that will help to contain energy production and help to reduce emissions from the coal industry. Viable measures are seen in carbon capture technologies (CCTs). The main focus is on the environmental and economic comparison of two innovative CCTs that are integrated in the operational Czech energy units. The assessed scenarios are (1) the scenario of pre-combustion CO2 capture integrated into the gasification combined cycle (IGCC-CaL) and (2) the scenario of post-combustion capture by adsorption of CO2 by activated carbon (PCC-A). An environmental assessment is performed through a life-cycle assessment method and compares the systems in the phase of characterization, normalization, and relative contribution of the processes to the environmental categories. Economic assessment compares CCT via capture and avoided costs of CO2 and their correlation with CO2 allowance market trend. The paper concludes with the selection of the most suitable CCT in the conditions of the Czech Republic by combining the scores of environmental and economic parameters. While the specific case of IGCC-CaL shows improvement in the environmental assessment, the economic analysis resulted in favor of PCC-A. The lower environmental–economic combination score results in the selection of IGCC-CaL as the more viable option in comparison with PCC-A in the current Czech energy and economic conditions.

To estimate the synergistic emission reduction effect resulting from carbon emissions trading scheme (ETS) pilots launched in 2013, this study estimated the synergistic emission reduction relationship between carbon dioxide (CO2) and atmospheric pollutants, consisting of sulfur dioxide (SO2), nitrogen oxides (NOX), dust pollutants (Dust) and particulate matter 2.5 (PM2.5). Using the extended logarithmic mean Divisia index (LMDI) method and the IPAT equation, the synergistic emission reduction effect was decomposed into direct and indirect categories driven by energy efficiency, economic development and industrial structure. Moreover, the synergistic emission reduction effect of ETS pilots was quantified with the difference-in-differences method (DID) and propensity score matching difference-in-differences method (PSM-DID). The results show that, from 2013 to 2016, CO2 and atmospheric pollutants achieved emission reduction synergistically through ETS, among which the synergistic emission reduction effect between CO2 and SO2 was most significant. Compared with the direct category, the indirect category accounted for smaller proportion of the synergistic emission reduction effect. The combined action of energy efficiency and industrial structure has a potential positive influence on synergistic emission reduction effect of ETS. Consequently, this suggests that the government needs to develop the domestic carbon market further, improve energy efficiency and optimize industrial structure to promote synergistic emission reduction.

This paper provides a comparative analysis using the concept of life cycle assessment (LCA), between high-sulfur (3000 ppm) and low-sulfur diesel (500 ppm) diesel. The comparative LCA considers the stages of production, transport and oil refining , as well as the transport of refined products and their respective end use. This last stage of the life cycle is important for the analysis of potential environmental impacts, due to sulfur oxide (SOx) emissions, which contribute to the formation of acid rain, damage air quality and the ecosystem (land and water acidification), causing gradual damage to human health and the environment. Therefore, comparative LCA identifies critical points from the environmental perspective, weighing the contributions of pollutants (NO2, CH4 and CO2) known as greenhouse gases (GHG) and criteria pollutants (CO, SOX, NOX, VOC's and PM). Simapro 7.2® was used to simulate and evaluate potential environmental impacts generated during the production and use by end consumers of the two fossil fuels. In order to evaluate the impact categories, two methods available in said calculation tool were selected: the first is the IPCC-2007 (GWP-100years), which estimates the carbon footprint and the contributions of each stage of the production chain to the "Global Warming" effect. The second method of evaluation is the Impact 2002+, which assesses the various contributions to the categories of toxicity to "Human Health", "Ecosystem Quality", "Climate Change" and "Depletion of Natural Resources". Thus, the preliminary results of comparative LCA show a slight increase in the carbon footprint (total emissions of CO2 equivalent in the productive chain) of low-sulfur diesel, approximately 3.8% compared to high-sulfur diesel, as a result of the increased emissions generated by the operation of the hydrogenation plant. However, low-sulfur diesel achieves a significant reduction of about 80% in comparison with high-sulfur diesel, in terms of damage to "Human Health" and "Ecosystem Quality". On the contrary, there was an increase of 2% and 6% in the categories of "Climate Change" and "Depletion of Natural Resources", respectively. Finally, despite the minor increase in the carbon footprint, although with remarkable reductions in "Ecosystem Quality" and "Human Health", the production and use of low-sulfur diesel has a single score of environmental impact equivalent to 0.23 milli points (mPt) compared to the single score obtained by high-sulfur diesel of 1.23 (mPt).

Increasing soil organic carbon (SOC) in Australian farming systems has the potential to offset greenhouse gas emissions. Even though methods for soil carbon (C) sequestration have been developed under the Australian Government’s Emissions Reduction Fund, the scope for farm-scale soil C sequestration is poorly understood. A pilot scheme was developed in Central West New South Wales to trial the use of a market-based instrument to encourage farmers to change farm management to increase SOC. This paper reports changes to SOC stocks measured on farms that were successfully contracted in the pilot. The 10 contracted farms were those that submitted the lowest bid per Mg CO2-e. Four land uses were contracted in the pilot: (1) reduced tillage cropping (reference); (2) reduced tillage cropping with organic amendments (e.g. biosolids or compost); (3) conversion from cropping land to permanent pasture; and (4) conversion from cropping land to permanent pasture with organic amendments. At each site a minimum of 10 locations (sampling points) were sampled and analysed for total carbon (LECO elemental analyser) and bulk density calculated. The SOC stocks (0–0.3 m) were assessed before (2012) and after the pilot (2017; calculated on equivalent soil mass of 2012), with 60% of sites showing a significant increase. Pasture had a higher rate of SOC sequestration than reduced tillage cropping (1.2 vs 0.28 Mg C ha–1 year–1, 0–0.3 m); and organic amendments had higher rates of SOC sequestration than without (1.14 vs 0.78 Mg C ha–1 year–1, 0–0.3 m). The results of the pilot demonstrated increases in SOC, using quantification methods consistent with the current Measurement Method of the Australian Government’s Emissions Reduction Fund policy used to generate Australian Carbon Credit Units. The results require careful interpretation as rates of sequestration are likely to be lower in the longer term than initial rates of change seen in this pilot (five years), and the pilot intentionally selected sites with initially low SOC, which ensured a greater opportunity to sequester SOC.

The aim of this article is to assess and explain the effectiveness of the international climate regime in a problem-solving perspective, with a focus on mitigation. As CO2 emissions have increased by more than 60 per cent since the start of the climate negotiations, effectiveness is exceedingly low. In explaining the performance of the regime, the main focus is on its problem-solving ability, defined as a function of power, leadership, and institutional design. ‘Negative’ power and a lack of leadership constitute important reasons for low effectiveness. In this broader perspective, the role of institutional design, exemplified by the Paris Agreement and its Rulebook, is fairly modest, and its significance should not be exaggerated. The Agreement and Rulebook score high in terms of ambition, but whether the rules will ever realize those ambitions remains to be seen. Domestic interests and priorities of the most important emitting countries will be decisive in this regard.

To combat the rutting effect and other distresses in asphalt concrete pavement, certain modifiers and additives have been developed to modify the asphalt mixture to improve its performance. Although few additives exist, nanomaterials have recently attracted significant attention from the pavement industry. Several experimental studies have shown that the use of nanomaterials to modify asphalt binder results in an improved oxidative aging property, increased resistance to the rutting effect, and improves the rheological properties of the asphalt mixture. However, despite the numerous benefits of using nanomaterials in asphalt binders and materials, there are various uncertainties regarding the environmental impacts of nano-modified asphalt mixtures (NMAM). Therefore, this study assessed a Nano-Silica-Modified Asphalt Mixtures in terms of materials production emissions through the Life Cycle Assessment methodology (LCA), and the results were compared to a conventional asphalt mixture to understand the impact contribution of nano-silica in asphalt mixtures. To be able to compare the relative significance of each impact category, the normalized score for each impact category was calculated using the impact scores and the normalization factors. The results showed that NMAM had a global warming potential of 7.44563 × 103 kg CO2-Eq per functional unit (FU) compared to 7.41900 × 103 kg CO2-Eq per functional unit of the conventional asphalt mixture. The application of LCA to NMAM has the potential to guide decision-makers on the selection of pavement modification additives to realize the benefits of using nanomaterials in pavements while avoiding potential environmental risks.

Meat replacers could play a role in achieving more plant-based diets, but their current consumption is limited. The present modelling study aimed to explore the nutritional and greenhouse gas emissions impacts of meat replacers. Using dietary surveys from Denmark, Czech Republic, Italy and France (~6500 adults), we composed alternative diets in which all the meat in the observed diet (in grams) was substituted by similar use meat replacers (with and without fortification). Starting from the observed diets and meat-replacement diets, diets with improved adherence to food-based dietary guidelines (FBDGs) were modelled using Data Envelopment Analysis. These improved diets were then further optimised for dietary preferences (MaxP, diet similarity index), nutrient quality (MaxH, Nutrient Rich Diet score, NRD15.3) or diet-related greenhouse gas emissions (GHGE) (MaxS, CO2 equivalents). In all optimised modelled diets, the total amount of meat was lower than in the observed diets, i.e., 30% lower in the MaxP, 50% lower in the MaxH, and 75% lower in the MaxS diets. In the MaxP diet, NRD15.3 was ~6% higher, GHGE was ~9% lower, and ~83% of food intake remained similar. In the MaxH diet, NRD15.3 was ~17% higher, GHGE was ~15% lower, and ~66% of food intake remained similar. In the MaxS diet, NRD15.3 was ~9% higher, GHGE was ~33% lower, and ~65% of food intake remained similar. When using fortified meat replacers, for all modelled diets, the diet similarity was on average 2% lower and the GHGE reduction was on average 3% higher as compared with the same scenarios without fortification. This analysis showed that meat replacers, provided their preference is similar to meat, can provide benefits for GHGE, without necessarily compromising nutrient quality.

Life cycle assessment of wood energy: factors for high ecological benefits Wood energy is increasingly used to replace non-renewable energy sources. Energy wood is a limited resource and should therefore be used wisely not only to maximize the economic but also the environmental benefits associated with its use. This article assesses the environmental burdens associated with wood energy (for heat, electricity and transportation) and the benefits that may arise when non-renewable energy technologies are substituted. It is shown that from a global warming perspective the use of wood energy seems almost always beneficial, but this effect may be significantly reduced if biogenic CO2 is taken into account. The method of ecological scarcity on the other hand, which considers several additional environmental dimensions and combines these into a single score, shows significantly lower environmental benefits of wood in comparison with non- renewable energy. One of the principal reasons for this are air emissions associated with wood energy such as particulate matter, nitrogen oxides (NOx) and volatile organic carbon (VOC). Considerable environmental benefits can be achieved in both cases if the following three key factors are respected: 1) a wise choice of the substituted technology and the underlying energy carrier, 2) a high efficiency in the conversion from energy contained in biomass to final energy, and 3) the implementation of measures to reduce air emissions such as particle filters and, if possible, more advanced flue gas cleaning. The article then discusses the limits of the comparison and selected issues within the life cycle assessment methodology that need further development.

With the worldwide spread of emissions trading schemes (ETSs) and the need for international cooperation on climate change, there is growing interest in linking ETSs. Along with sustainable development, preventing and controlling pollution, is now regarded as an urgent priority by China and Korea. In the context of the willingness of the Chinese and Korean governments to cooperate on ETS, this paper examines the feasibility of a pilot ETS cooperation between Shanghai and Korea from environmental efficiency and CO2 marginal abatement cost (MAC) perspectives. We apply a directional distance function (DDF) and stochastic frontier analysis (SFA) to estimate the environmental efficiency and the CO2 MAC of coal-fueled power plants in Shanghai and Korea using cross-sectional data from 2015. The results indicate that the group frontier environmental efficiency of Shanghai and Korea reached a similarly high score. However, as to meta-frontier environmental efficiency, the coal-fueled power plants in Korea performed better than those in Shanghai. The CO2 MAC results indicate that, despite the small gap in efficiency performance, the CO2 MAC of coal-fueled power plants is much higher than that in Shanghai due to the big feed-in tariff difference. This is because the MAC not only relates to the environmental efficiency, but also to the feed-in tariff. A higher feed-in tariff leads to higher MAC. To tackle this serious problem, which has also been addressed in previous studies, we suggest that policymakers should focus on the huge CO2 MAC differences caused by feed-in tariff differences to avoid equity problems when building the structure of the Shanghai-Korea ETS cooperation. For instance, compared with power plants in Shanghai, policymakers should set a looser cap and a higher offset for Korean plants. To reduce the impact of feed-in tariff on carbon trading in the market, it would also be effective to arrange a higher quota or a lower carbon tax for coal-fueled power plants in Korea. In addition, policymakers should fill the gaps of 85.15% and 67.6% between the realistic market price and the MAC results of coal-fueled power plants in Shanghai and Korea, respectively, by introducing stricter regulations.

The paper deals with the analysis of methodology of Environmental Performance Index. The authors analyzed and systematized the main existing integrated indices, which were used for evaluation of environmental, social and economic situation in the countries. The authors allocated the environmental performance index as a basis for analyzing the environmental policy of the country. In this direction, the authors analysed the main features, structure and indicators of environmental performance index. The authors allocated the world-leader countries with huge level of CO2 emissions. According to the results, the authors aproved that these countries should improve their environmental policy. Accordingly, they occupied less position in environmental performance index. For the purpose to analyze the relation between ecological, social and economic welfare, the authors analyzed score of sustainable development goal index, social progress index and gross domestic product per capita. The comparison analysis of findings showed that countries with good position on environmental performance index have the strong position on sustainable development goal index and social progress index. The authors suggested that Ukraine should orient to the EU countries with purpose to improve the environmental policy.

The European Union is planning a new program to achieve climate neutrality by 2050. In this context, the Icelandic government plans to ban new registrations of fossil fuel cars after 2030 as one of the strategies to make Iceland a carbon-neutral country by 2040. Upgraded biogas can be directly used in vehicles with CNG engines, reducing CO2 emissions by 80%. In this paper, several alternatives of biogas plants, simulated in previous research, were evaluated by considering techno-economic and environmental criteria through the application of multi-criteria decision-making tools. Twelve alternatives were analyzed using the Definite 3.1 software. A weighted summation algorithm, which transforms all criteria into the same scale by multiplying them by weights and then summing them to obtain the results, was used in the analysis. The multi-criteria analysis of the twelve proposed alternatives included eleven criteria (three technical, five economic, and three environmental) whose weights were changed in a total of eleven scenarios. From a global perspective, when all criteria were considered (9.1% weight) the best alternative with a score of 0.58 was the single-stage biogas plant working with municipal solid waste. Sensitivity and uncertainty analyses also demonstrated that the multi-criteria results obtained were robust and reliable.

Abstract Objectives This research explored the relationship between greenhouse gas emissions (GHGE) and nutrient density of lunches served at a large urban school district in New England to support menu planning. We hypothesized that nutrient density would be inversely associated with GHGE. Methods The school district provided information on lunch menus for the 2018–2019 school year. Nutrient density was calculated using the Nutrient Rich Food hybrid score (NRFh). Data on GHGE of foods and agricultural commodities was obtained from the database of Food Impacts on the Environment for Linking to Diets. Under the Offer vs. Serve provision, the school district allows students to select from a variety of lunch combinations to receive a federally reimbursable meal. Federally reimbursable meals must contain at least three meal components and one meal component must be a fruit or vegetable. We calculated the correlation between GHGE and NRFh for all qualifying reimbursable lunch combinations offered during the 2018–2019 school year. Results We assessed 120,746 possible reimbursable lunch combinations. The mean GHGE and NRFh of lunches was 0.76 kg CO2 eq lunch−1 and 1.93, respectively. There was a weak negative correlation (r = −0.15) between GHGE and NRFh. Entrees of lunches with the lowest GHGE (≤ 5th percentile) and highest NRFh (≥ 95th percentile) contained grains, tofu, and legumes, and in few instances cheese and poultry. Entrees of lunches with the highest GHGE (≥ 95th percentile) and lowest NRFh (≤ 5th percentile) contained beef or beef and cheese. Lunches with the lowest GHGE (≤ 5th percentile) did not include fluid milk. Foods with low NRFh were high in sodium and/or saturated fat, foods with high NRFh contained nuts, seeds, and/or whole grains. Conclusions Greenhouse gas emissions and nutrient density are only weakly correlated for school lunches; this suggests that nutritiousness of foods should not be used to predict GHGE for school lunches. Our findings show that schools currently provide options which are highly nutritious and produce low GHGE, however the question remains on how to encourage the consumption of these options.

The primary objective of this study was to validate the sustainability benchmarking tool (SBT) framework proposed by the authors in a previous study. The SBT framework is focused on benchmarking triple bottom line (TBL) sustainability through exhaustive use of lean, six-sigma, and life cycle assessment (LCA). During the validation, sustainability performance of a value-added wood products’ production line was assessed and improved through deployment of the SBT framework. Strengths and weaknesses of the system were identified within the scope of the bronze frontier maturity level of the framework and tackled through a six-step analytical and quantitative reasoning methodology. The secondary objective of the study was to document how value-added wood products industries can take advantage of natural properties of wood to become frontiers of sustainability innovation. In the end, true sustainability performance of the target facility was improved by 2.37 base points, while economic and environmental performance was increased from being a system weakness to achieving an acceptable index score benchmark of 8.41 and system strength level of 9.31, respectively. The social sustainability score increased by 2.02 base points as a function of a better gender bias ratio. The financial performance of the system improved from a 33% loss to 46.23% profit in the post-improvement state. Reductions in CO2 emissions (55.16%), energy consumption (50.31%), solid waste generation (72.03%), non-value-added-time (89.30%), and cost performance (64.77%) were other significant achievements of the study. In the end, the SBT framework was successfully validated at the facility level, and the target facility evolved into a leaner, cleaner, and more responsible version of itself. This study empirically documents how synergies between lean, sustainability, six-sigma and life cycle assessment concepts outweigh their divergences and demonstrates the viability of the SBT framework.

In the fight against climate change, the utilization of renewable energy resources is being encouraged in every country all over the world to lessen the emissions of greenhouse gases. However, not all countries are able to efficiently utilize these resources, and instead of providing solutions, the inefficient use of renewable energy may lead to even more damage to the environment. Data from eight countries belonging to the highly industrialized countries (HIC) group and nine from newly industrialized countries (NIC) group were used to evaluate the energy utilization of these groups. Factors such as total renewable energy capacity, the labor force, and total energy consumption were considered to be the input factors, while, CO2 emission and gross domestic product are the output factors. These factors were used to calculate efficiency scores of every country from 2013 to 2018 using the undesirable output model of Data envelopment analysis (DEA). The grey prediction model was also used to measure the forecasted values of the input and output factors for the year 2019 to 2022, and measure again the future efficiency scores of the HICs and NICs. The combination of grey prediction and DEA undesirable output model made this paper unusual and the most appropriate method in dealing with data that contains both desired and undesired outputs. The results show that the United Kingdom, Germany, France, and the United States continuously top the efficiency ranking among the HIC group, with a perfect 1.0 efficiency score from 2013 to 2022. Russia demonstrates the lowest score of 0.1801 and is expected to perform the same low-efficiency score in the future. Within the NIC group, Indonesia can be highlighted for performing with perfect efficiency starting from the year 2015 and even through 2022. Other NICs are performing at a very low-efficiency, with scores ranging from 0.2278 to 0.2734 on average, with Turkey displaying the lowest rank. This study recommends some useful strategies to improve the utilization of renewable energy resources such as improvements in the political and legal structure surrounding their use and regulation, tax incentives or exemptions to private power producers to encourage shifting away from conventional energy production, partnerships with non-governmental and international organizations that can provide assistance in managing renewable energies, strengthening of the energy sector’s research and development activities and long-term strategic plans for the development in renewable energy with considerations to the social, environmental, and economic impact on each country.

Abstract. Global terrestrial ecosystems control the atmospheric CO2 concentration through gross primary production (GPP) and ecosystem respiration processes. Chlorophyll fluorescence is one of the energy release pathways of excess incident light in the photosynthetic process. Over the last 10 years, extensive studies have revealed that canopy-scale Sun-induced chlorophyll fluorescence (SIF), which potentially provides a direct pathway to link leaf-level photosynthesis to global GPP, can be observed from satellites. SIF is used to infer photosynthetic capacity of plant canopy; however, it is not clear how the leaf-level SIF emission contributes to the top-of-canopy directional SIF. Plant canopy radiative transfer models are useful tools to understand the mechanism of anisotropic light interactions such as scattering and absorption in plant canopies. One-dimensional (1-D) plane-parallel layer models (e.g., the Soil Canopy Observation, Photochemistry and Energy fluxes (SCOPE) model) have been widely used and are useful to understand the general mechanisms behind the temporal and seasonal variations in SIF. However, a 1-D model does not explain the complexity of the actual canopy structures. Three-dimensional models (3-D) have a potential to delineate the realistic directional canopy SIFs. Forest Light Environmental Simulator for SIF (FLiES-SIF) version 1.0 is a 3-D Monte Carlo plant canopy radiative transfer model to understand the biological and physical mechanisms behind the SIF emission from complex forest canopies. The FLiES-SIF model is coupled with leaf-level fluorescence and a physiology module so that users are able to simulate how the changes in environmental and leaf traits as well as canopy structure affect the observed SIF at the top of the canopy. The FLiES-SIF model was designed as three-dimensional model, yet the entire modules are computationally efficient: FLiES-SIF can be easily run by moderate-level personal computers with lower memory demands and public software. In this model description paper, we focused on the model formulation and simulation schemes, and showed some sensitivity analysis against several major variables such as view angle and leaf area index (LAI). The simulation results show that SIF increases with LAI then saturated at LAI>2–4 depending on the spectral wavelength. The sensitivity analysis also shows that simulated SIF radiation may decrease with LAI at a higher LAI domain (LAI>5). These phenomena are seen in certain Sun and view angle conditions. This type of nonlinear and nonmonotonic SIF behavior towards LAI is also related to spatial forest structure patterns. FLiES-SIF version 1.0 can be used to quantify the canopy SIF in various view angles including the contribution of multiple scattering which is the important component in the near-infrared domain. The potential use of the model is to standardize the satellite SIF by correcting the bidirectional effect. This step will contribute to the improvement of the GPP estimation accuracy through SIF.

AbstractIntroductionFood consumption is important for population as well as planetary health. Globally, fresh water is a scarce resource. For both fresh water use and greenhouse gas (GHG) emissions a risk of exceeding the planetary boundaries exists. Food production accounts for approximately 90% of the global water footprint and for 30% of global greenhouse gas emissions. In this study, the Dutch food consumption patterns are evaluated for blue water use and greenhouse gas emission and its association with dietary quality (Dutch Healthy Diet index 2015).Materials and MethodsFood consumption was assessed, in 2012–2016, by two non-consecutive 24 h recalls, in Dutch children and adults aged 1–79 y (n = 4313) (www.wateetnederland.nl). Environmental impact of foods was quantified using life cycle assessment for e.g. indicators (blue) water use and GHG emission. For each participant aged ≥ 18 y (n = 2078), a score was calculated for the Dutch Healthy Diet 2015 index (DHD15) to quantify the quality of diet with respect to health. Statistical analyses were stratified for age and gender.ResultsDaily diets in the Netherlands were associated with 0.14 ± 0.10 m3 blue water use and 5.3 ± 2.4 kg CO2-equivalents GHG emission. Non-alcoholic beverages, nuts and fruits were most important food groups for use of blue water, and meat, dairy and non-alcoholic beverages for GHG emission. DHD15 score was 4.2 ± 1.5 for men and 4.9 ± 1.4 for women. Diets with a higher DHD15 score had a higher blue water use (r = 0.17) and a lower GHG emission (r = -0.35).DiscussionDifferent associations of environmental indicators (blue water use and GHG emission) with health aspects of diets need to be considered when aligning diets for health and sustainability.

The 2030 Agenda of 17 Sustainable Development Goals is to promote well being, peace and prosperity among people at presents and future. Goal 9 focuses on “Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation”. The score of this goal according to Sustainable Development report is 33.1. Air pollution is the top killer in the world (Thomson Reuters 2018), every year all countries face heavy natural calamities disaster which results in huge human loss and financial losses thereby leading to global inequality and environmental injustice. The most important source of global warming is Tropical deforestation, rising the release of different gases into the atmosphere, burning of fossil fuels etc. Increase in CO2 emissions will produce more heat, thereby directly affecting our natural resources which results in more disease and increase in water level. Almost all countries contribute to the rise of carbon emission, the Paris agreement pledges that nearly 200 nations will limit global warming to 3C. India is the second largest populated country, it has launched the smart city project, Government wants to implement 100 smart cities, and it is worth to develop 100 smart villages. Smart class rooms, good and healthy environment and hospitals must be focused and developed in villages, which will act as a tool to achieve 2030 Goal. Based on the above theory the current paper attempts to study the world and region wise data regarding the human impacts of fossil-fuel pollution, Worlds’ Ranking on fossil fuel CO2 emissions rates, waterless economies, Investment potential and opportunities in cities by region and sector to 2030 etc. Secondary data of various sources from Sustainable Development report, water polluted report, Carbon dioxide Information Analysis, world bank, etc., is collected. Simple graphs, growth rate, percentage analysis, data visualization techniques are used to verify the above objective, based on the detail discussions, policy suggestions are provided

Abstract. Le TL, Luu TTH, Huynh N, Chung RH. 2020. Environmental efficiency of rice production in Vietnam: An application of SBM-DEA with undesirable output. Biodiversitas 21: 2710-2715. In Vietnam, the agricultural sector is one of major sources of the country’s greenhouse gas (GHG) emissions and over half of that comes from rice cultivation. This study evaluates the environmental efficiency of 400 rice farms in the Mekong Delta using slack-based measure (SBM) data envelopment analysis (DEA) with considering the total amount of CO2-equivalent (CO2-eq) emissions in the rice field as undesirable output. The findings revealed that the average environmental efficiency score of the farmers was very low, just only 0.461. Only 2.25% of the sample farms were environmentally efficient while majority of them (58%) obtained the efficiency values less than the mean indicating that their environmental efficiency needs to be further improved. The small rice farms were higher in environmental efficiency scores compared with large farms. The sample rice farmers who are members of agricultural cooperatives obtained a significantly higher environmental efficiency than the non-cooperative members. The estimated results of input and bad output excesses showed that about 1.35 tons of CO2-eq ha-1 could be reduced and an average of 54.18 kg N ha-1 could be saved in order to improve the environmental performance of rice production in the study area.

AbstractThe Swedish system for determining fairway dues at the national level is acknowledged as being unique in attempting to consider the environmental performance of vessels. Between 1998 and 2014, vessels could get a SOX discount and between 1998 and 2017 a NOx discount, both based on certificates. In 2018, the Swedish government initiated a new system comprising more environmental impacts requiring operators that want to benefit from it, to register their vessels for a score in the Clean Shipping Index (CSI). The CSI covers performance in five categories: NOX, CO2, SOX/PM, Chemicals and Waste. Based on received scores, vessels can get 10%, 30% or 90% discount. In this paper, the short-term outcome of the new system is analysed and compared to the old NOX-based system. The comparison is based on revealed preferences of the involved vessel operators. Vessel specific data about the discounts and scores are analysed as well as the regional distribution of discounts and impacts on different vessel types. The paper shows that the Swedish Maritime Administration has succeeded in creating a system that attracts more vessel types and encompasses more environmental categories, but that the incentives to reduce NOX emissions have been reduced. Ex-post cost-benefit analyses of the earlier certificate-based systems have proven them beneficial to society. However, it is unclear how the outcome of the new system will be. The paper suggests that there are efficiency gains in harmonising the system SMA has introduced with the different systems for environmentally differentiated port fees in Sweden.

The evolution of machine learning (ML) algorithms provides researchers and engineers with state-of-the-art tools to dynamically model complex relationships. The design and operation of municipal solid waste (MSW) management systems require accurate estimation of generation rates. In this study, we applied rapid, non-linear and non-parametric data driven ML algorithms independently, multi-layer perceptron artificial neural network (MLP-ANN) and support vector regression (SVR) models to predict annual MSW generation rates in Bahrain. Models were trained and tested with MSW generation data for period of 1997–2019. The population, gross domestic product, annual tourist numbers, annual electricity consumption and total annual CO2 emissions were selected as explanatory variables and incorporated into developed models. The zero score normalization (ZSN) and minimum maximum normalization (MMN) methods were utilized to improve the quality of data and subsequently enhances the performance of ML algorithms. Statistical metrics were employed to discriminate performance of MLP-ANN and SVR models. The linear, polynomial, radial basis function (RBF) and sigmoid kernel functions were investigated to find the optimal SVR model. Results showed that RBF-SVR model with R2 value of 0.97% and 4.82% and absolute forecasting error (AFE) for the period of 2008 and 2019 exhibits superior prediction and robustness in comparison to MLP-ANN. The efficacy of MLP-ANN model was also reasonably successful with R2 value of 0.94. It was shown that MMN pre-processing generated optimal MLP-ANN model while ZSN pre-processing produced optimal RBF-SVR model. This work also highlights the importance of application of ML modelling approaches to plan and implement their roadmap for waste management systems by policymakers.

The release of Al Gore’s An Inconvenient Truth and his subsequent training of thousands of Climate Presenters marks a critical transition point in communication around climate change. An analysis of Al Gore’s An Inconvenient Truth presentation and of the guidelines we were taught as Presenters in The Climate Project, show they reflect the marketing principles that the World Wildlife Fund (WWF) report Weathercocks and Signposts (Crompton) argues cannot achieve the systemic and transformational changes required to address global warming. This paper will consider the ultimate effectiveness of social marketing approaches to Climate change communication and the Al Gore Climate Project in the light of the WWF critique. Both the film and the various slideshow presentations of An Inconvenient Truth conclude with a series of suggestions about how to “how to start” changing “the way you live.” The audience is urged to: Reduce your own emissions Switch to green power Offset the rest Spread the word The focus on changing individual consumption in An Inconvenient Truth is also reflected in the climate campaign page Get Involved on the website of the Australian Conservation Foundation (ACF)—the Australian partner in Al Gore’s The Climate Project (TCP). Al Gore’s Climate Project, with over 3,000 Climate Presenters worldwide, could be seen as a giant experimental test of the merits of marketing approaches to social change as compared to the recommendations in the WWF critique authored by Crompton. In Orion magazine, Derrick Jensen has described this emphasis on “personal consumption” instead of “organized political resistance” as “a campaign of systematic misdirection.” Jensen points out that “even if every person in the United States did everything the movie suggested, U.S. carbon emissions would fall by only 22 percent.” The latest scientific reports show we are on the edge of a tipping point into catastrophic climate change—runaway warming which would render the planet uninhabitable for most life forms, including humans (Hansen et al 13). To reduce the risk of catastrophic climate change to a still worrying 13% we need significant action between now and 2012, and carbon dioxide levels will need to be stabilised at between 350 and 375 parts per million by 2050 (Elzen and Meinshausen 17). Because Americans and Australians are taking far more than our share of the global atmospheric commons, we need to reduce our emissions to less than 90% below 1990 levels by 2050 as our share of the global emission reduction targets (Elzen and Meinshausen 24; Garnaut 283). In other words, if one takes the science seriously there is a huge shortfall between the reductions which can be achieved by individual changes to consumption and the scale of reductions that are required to reduce the risk of catastrophic climate change to a half-way tolerable level. The actions being promoted as solutions are nowhere near “inconvenient” enough to solve the problem. Like Crompton and Jensen I was inclined to take the gap between goal and means as overwhelming evidence for the inadequacy of marketing approaches emphasising changes to individual consumption choices. Like them I was concerned that the emphasis on consumption in marketing approaches may even reinforce the consumerism and materialism that drives the growth in emissions. Whilst being generally critical of marketing approaches, Crompton says he accepts the importance marketers place on tailoring the message to fit the motivations of the target audience (25). However, while Crompton describes Rose and Dade’s “Values Modes analysis” as “a sophisticated technique for audience segmentation” (21), he rejects the campaign strategies designed around the target audiences they identify (23). Market segmentation provides communications practitioners with the “extensive knowledge of whom you are trying to reach and what moves them” which is one of the “three must haves” of a successful communication campaign (Fenton 3). Rose and Dade’s segmentation analysis categorises people based on the motivational hierarchy in Maslow’s Hierarchy of Needs. They identify three population groupings—the Settlers, driven by security; the Prospectors, esteem driven; and the Pioneers, who are motivated by intrinsic values (1). As with Maslow’s hierarchy these “Values Modes” are developmentally dynamic. The satisfaction of more basic needs, like physical safety and economic security, support a developmental pathway to the next level. Just as the satisfaction of the need for social acceptance and status free the individual to become motivated by self-actualisation, universal and compassionate ethics, and transcendence. Because individuals move in and out of Values Modes, depending on the degree to which economic, social and political conditions facilitate the satisfaction of their needs, the percentage of the population in each group varies across time and location (Rose and Dade 1). In 2007 the UK population was 20% Settlers, 40% Prospectors, and 40% Pioneers (Rose and Dade 1), but the distribution in other countries would need to be determined empirically. Rose et al provide a strategic rationale for a marketing based climate campaign targeted at changing the behaviours of Prospectors, rather than appealing to Pioneers. While the Pioneers are 40% of the population, they don’t like being “marketed at,” they seek out information for themselves and make up their own minds, and “will often have already considered your ideas and decided what to do” (6). They are also well catered for by environmental groups’ existing ethical and issues based campaigns (3). Prospectors, on the other hand, are the 40% of the population which are the “least reached” by existing ethical or issues oriented environmental campaigning; are the most enthusiastic (or “voracious”) consumers, so their choices will sway business; and they tend to be swinging voters, so if their opinions change it will sway politicians (4). Rose et al (13) found that in order to appeal to Prospectors a climate change communications campaign should: Refer to local, visible, negative changes involving loss or damage [In the UK] show the significance of UK emissions and those of normal people (i.e. like them) Use interest in homes and gardens Deploy the nag factor of their children Create offers which are above all easy, cost-effective, instant and painless Prospectors don’t like, and will be put off by campaigns that (Rose et al 13): Talk about the implications: too remote and they are not very bothered Use messengers (voices) which lack authority or could be challenged Criticise behaviours (e.g. wrong type of car, ‘wasting’ energy in your home) Ask them to give things up Ask them to be the first to change (amongst their peers) Invoke critical judgement by others Crompton recommends an environmental campaign that attempts to persuade Prospectors that they are wrong in thinking material consumption and “ostentatious displays of wealth” contribute to their happiness. Prospectors see precisely these sorts of comments by Concerned Ethicals as a judgemental criticism of their love of things, and a denial of their need for the acceptance and approval of others. Maslow’s developmental model, as well as the Value Modes research, would suggest that Crompton’s proposal is the exact opposite of what is required to move Prospectors into the Pioneer value mode. It is by accepting the values people have, and allowing them to meet the needs that drive them, that they can move on to more intrinsically motivated action. Crompton would appear to fall into the common “NGO or public sector campaign […] trap” of devising a campaign based on what will appeal to the 10% of the population that are Concerned Ethicals, but in the process “particularly annoy or intimidate” the strategically significant 40% of the population that are Prospectors (Rose et al 8). Crompton ignores the evidence from marketing campaign research that campaigns can’t directly change people’s basic motivations, while they can change people’s behaviours if they target their existing motivations. Contrary to Crompton’s claim that promoting green consumption will reinforce consumerism and materialism (16), Rose and Dade base their campaign strategy on the results of research into cognitive dissonance, which show that if you can get someone to act a certain way, they will alter their beliefs and preferences, as well as their self concept, to fit with their actions. Crompton confuses a tactic in a larger game, with the end goal of the game. “The trick is to get them to do the behaviour, not to develop the opinion” (Rose, “VBCOP” 2). Prospectors are persuaded to adopt a behaviour if they see it as “in,” and as what everyone else like them is doing. They are more easily persuaded to buy a product than adopt some other sort of behavioural change. The next part of an environmental marketing strategy like this is to label, praise and reward the behaviour (Futerra 11). Rose suggests that Prospectors can be engaged politically if governments are called on to recognise and reward the behaviour “say by giving them a tax break or paying them for their rooftop energy contribution” (“VBCOP” 3). Once governments have given such rewards, both Settlers and Propectors will fight to keep them, where they are normally disinclined to fight political battles. Once Prospectors identify themselves as, for example, in favour of renewable energy, politicians can be persuaded they need to act to get and keep votes, and business can be persuaded to change in order to continue to attract buyers for their products. In order to achieve the scale of emission reductions required individuals need to change their consumption patterns; politicians need to change the regulatory and planning context in which both individual and corporate decisions are made; and the economic system needs to be transformed so it internalises environmental costs and operates within environmental limits. Social marketing analyses have identified changing Prospectors buying habits as the wedge, or leverage point that can lead to such a cascading set of social, political and economic changes. Just as changing Prospector product choices can be exploited as a key leverage point, Al Gore identified getting United States commitment to emission reduction as a key leverage point towards achieving global commitments to binding reduction targets. Because the United States had the highest national greenhouse emissions, and was one of the two industrialised countries who had failed to sign the Kyoto Protocol, changing behaviour and belief in the United States was strategically critical to achieving global action on emissions reduction. Al Gore initially attempted to get the United States to sign the Kyoto Protocol and commit to emission reduction by working directly at the political level, without building the popular support for action that would encourage other politicians to support his proposals. In the movie, Al Gore talks about the defeat of his initial efforts to get the United States to sign the Kyoto Protocol, and of his recognition of the need to gain wider public support before political action would be taken. He talks about the unsuitability of the mass news media as a vehicle for achieving social and political change on climate emissions. The priority given to conflict as a news value means journalists focus on the personalities involved in disputes about climate change rather than provide an analysis of the issue. When climate experts explain the consensus position of the Intergovernmental Panel on Climate Change (IPCC), they are “balanced” with opposing statements from the handful of (commonly fossil fuel industry funded) climate deniers. Because climate emissions are part of a complex process of slow change occurring over long time lines they do not fit easily into standard news values like timeliness, novelty and proximity (Harrison). When Al Gore realised he wouldn’t be able to gain the wider public support he needed through the mass news media he began a quest to spread his message “meeting by meeting,” “person by person.” Al Gore turned his slide show into a movie in order to deliver the message to more people than he could reach face to face, and then trained Presenters to reach even more people. When the movie won an Oscar for Best Documentary it turned Al Gore into something of a celebrity. Al Gore’s celebrity status rubs off on Climate Presenters through their association with him, giving them access to community and business groups across the world. When a celebrity recommends or displays a behaviour, Prospectors are more likely to see it as the in thing and thus more willing to do the recommended action. The movie created an opportunity for Al Gore to be a more persuasive messenger than he had been as a politician. Al Gore began The Climate Project to increase the impact of the movie and spread the message further than he could take it by himself. The multiplication of modes of communicating the message fits with Fenton Communications’ “Rule of Three.” In Now Hear This they say the target audience “should read about us in the paper, see us on TV, hear about us from a neighbour and a friend […] have their kid mention us […] and so on” (17). The Presenter training emphasises the “direct communication, especially face to face” recommended by Rose (“To do” 174). During the Presenter training Al Gore warned of the danger of being too negative as it risked moving people “from denial to despair without stopping to act,” and of the need to present the story in such a way as to create hope. This is backed up by the communications marketing literature, which warns that “negative messages may actually induce despair and actually [sic] paralysis while the positive focus can inspire” (Boykoff 172). While it employs dramatic visual images and animations, the movie tends to downplay the potential severity of the consequences of runaway global warming, and presents these in a way that gives the impression of a contracted time frame for the consequences of warming in order to activate motivation based on near term implications. The movie responds to Prospectors’ disinterest in distant implication of climate change by emphasising near-term threats, such as the rising monetary cost of damages, as well as threats to life and property from disease, drought, fire, flood, storm, and rising sea levels. After training an initial round of American Presenters, Al Gore identified training Australian Presenters as the next strategic priority. While Australia’s collective emissions are small, our per capita emissions are higher than those of Americans, and as the only other industrialised nation that had not signed, it was believed our becoming a signatory to the Kyoto Protocol would increase the pressure on the United States to sign. The ACF provided Australian Presenters with additional slides containing vivid images of Australian impacts, and Presenters were encouraged to find their own examples to illustrate impacts relevant to specific local audiences. The importance of identifying local impacts to persuade and move their audiences is impressed upon Presenters during the training. Regular slide updates reinforce this priority. While authors like Crompton and Jensen note the emphasis on changes in consumption as suggested solutions to climate change, other elements of the presentation are just as important in appealing to Prospectors. Prospectors want to belong and gain status by doing whatever is highly regarded by others. The presentation has numerous slides emphasising who else has made commitments to Kyoto and emission reduction. The American presentation includes lists of other countries, and towns and states in the United States that had signed up to Kyoto. The Australian presentation includes graphics emphasising the overwhelming number of Australians who support action. Prospectors don’t like being asked to give things up, and the presentation insists on the high cost of failing to act, compared to the small cost of acting now. Doing something to stop climate change is presented as easy and achievable. Contrary to Crompton’s claim that promoting green consumption would not build the widespread awareness and support for the more far-reaching government action that is required to achieve systemic change (9), the results of recent opinion research show that upwards of 80% of Americans support effective and wide-ranging action to reduce emissions and develop new renewable energy technologies (Climate Checklist). Whereas it would not have been surprising if the financial crisis had dimmed the degree of enthusiasm for action to reduce greenhouse emissions, the high support for action on climate change in their polling continues to encourage the Australian government to use it as a wedge issue against the opposition. Without high levels of public support, there would be little or no chance that politicians would be willing to vote for measures that will reduce emissions. That the push for change in individual consumption choices was only ever one tactic in a wider campaign is also demonstrated by the other projects instigated by Al Gore and his team. Projects like RepoWEr America and WE can solve the climate crisis leverage the interest developed by the Climate Project to increase public pressure on politicians to support regulatory change. The RepoWEr America and WE can solve the climate crisis sites target individuals as citizens and make it easy for them to participate in the political process. Forms help them sign petitions, write letters and meet with their elected officials, write for newspapers and call in to talkback radio, and organise local community meetings or events. Al Gore’s own web site adds a link to the Live Earth company to add to these arsenals. Live Earth “creates innovative, engaging events and media that challenge global leaders, local communities and every individual to actively participate in solving our planet's urgent environmental crises.” These sites provide the infrastructure to make it easy for individuals to move into action in the political domain. But they do it in ways that will appeal to Prospectors. They involve fun, their actions are celebrated, prizes are offered, the number of people involved is emphasised so they feel part of the “happening” thing. RepoWEr America and WE can solve the climate crisis help Prospectors to engage in political action in order to achieve regulatory change. Finally, or first, Al Gore’s Generation Investment Management Company, operating since 2004, is oriented towards systemic transformation in the economic system, so that economic drivers are aligned with sustainability imperatives. Al Gore and his partner David Blood reject Gross Domestic Product—the current measure of economic growth, and a major driver of unsustainable economic activity—as “dangerously imprecise in its ability to account for natural and human resources” and challenge business to accept the “need to internalize externalities” in order to create a sustainable economy. In their Thematic Research Highlights, Al Gore’s Generation company critiques the “Hedonic Treadmill”—which puts “material gains ahead of personal happiness” (32), and challenges “governments, companies, and individuals [...] to broaden their scope of responsibility to match their sphere of influence” (13). While the Climate Project would appear to ignore the inadequacy of individual consumption change as a means of emission reduction, the information and analysis targeted at business by Generation demonstrates this has not been ignored in the overall strategy to achieve systemic change. Al Gore suggests that material consumption should no longer be the measure of economic welfare, an argument he backs with an analysis showing business that long term wealth creation depends on accepting environmental and social sustainability as priorities. While An Inconvenient Truth promotes consumption change as the (inadequate) solution to Global Warming, this is just one strategically chosen tactic in a much larger and coordinated campaign to achieve systemic change through regulatory change and transformation of the economic system.
