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.

Sustainability and finance should go hand in hand. A financial system that supports sustainablegrowth is necessary for the transition to a carbon-free society. Environmental, Social andGovernance (ESG) is a sustainability performance measurement used worldwide. Previousresearch within the ESG area has mainly focused on ESG score and financial performance.Environmental performance gets more attention from investors, and the Nordic countries areall in the top five when it comes to sustainability ranking. This research examines the relationbetween sustainability ratings (E score and ESG score) in the Nordic countries as well as if therelation differs between different rating agencies. To study the relationships, a regressionanalysis was performed, and we could not draw any concrete conclusions whether low CO2emissions are associated with a higher E- or ESG score in the Nordic countries. The resultindicates that a high E- or ESG score does not seem to be associated with lower CO2 emissions.A significant result was found on the fact that the E- and ESG scores relation to CO2 aredifferent between rating agencies. However, full access to one of the rating agencies has notbeen granted, which entails some limitations and further research on the questions isrecommended.

Gasification combined cycle has the potential to provide a clean, high efficiency, low environmental impact power generation system. A prime fuel for such systems is coal but there is scope in part to utilise renewable energy sources including biomass and waste materials such as sewage sludge or even oil residues. There is considerable scope to improve the performance of the first generation systems of gasification combined cycle plant, both through design changes and through the continued development towards second generation plant. Such improvements offer the prospect of even better efficiency, coal/biomass/waste utilisation flexibility, lower emissions especially of CO2, and lower economic cost of power generation. There have been several major R&D initiatives, supported in part by the European Commission, which have been designed to meet these aims. The approach adopted has been to form multi-partner project teams comprising industry, industrial research organisations and selected universities. The main technical issues that have been considered include co-gasification, e.g. co-feeding, fuel conversion, gas quality, contaminants, component developments, and the integration of hot fuel gas cleaning systems for removal of solid particles, control of sulphur emissions, control of fuel bound nitrogenous species, removal of halides and control of alkali species. The technical R&D activities have been underpinned by several major techno-economic assessment studies. This paper provides an overview of these various activities which either form part of the European Commission JOULE Coal R&D Programme or were supported under an APAS special initiative.
