There is increasing interest in CO2 emissions inequality between and within countries, and concerns about the impacts of COVID-19 on vulnerable groups. In this study, the CO2 emissions inequality based on the different consumption category data of disaggregated income groups in eight developing countries is analyzed with the application of input-output model. We further examine the effects of the COVID-19 outbreak on CO2 emissions inequality based on the hypothetical extraction method, and the results reveal that the outbreak has decreased the CO2 emissions inequality and emissions over time. However, the shared socioeconomic pathway scenario simulation results indicate that long-term CO2 emissions inequality will persist. Targeted poverty elimination measures improve the utility of the low- and lowest-income groups and reduce CO2 emissions inequality. Reducing the excessive consumption on the demand side as well as improving the energy efficiency and increasing the share of renewable energy in the energy consumption on the supply side will provide more informed options to achieve multiple desirable outcomes, such as poverty elimination and climate change mitigation.

CO2 emissions embodied in international trade have drawn wide attention in the academia and national climate negotiations. In this study, we estimate the embodied CO2 emissions in the trade between China and Australia using long time series disaggregated sectoral data based on missions embodied in bilateral trade (EEBT) method, and analyse the major driving forces for these emissions changes based on structural decomposition analysis (SDA) method. The results show that export volume contributed to these embodied CO2 emissions increase, while emission intensity could offset these CO2 emissions increase. We further predict embodied CO2 emission in Sino-Australia trade under different scenarios and the results indicate that technology spillover can significantly reduce embodied CO2 emissions in trade. Electricity, transportation and cement industries have significant potential to reduce carbon emissions. In addition, we evaluate future carbon reduction potential till 2030. The results in this study can inform decision-makers for Australia and China to formulate energy conservation and emission reduction policies.

With the integration of the global economy and increased international trade, CO2 emissions embodied in trade have attracted broad attention. In this study, we examined Taiwan's CO2 emissions embodied in its imports and exports with its 167 trade partners from 1970 to 2015 using the emissions embodied in bilateral trade (EEBT) method. The results show that since the mid-1990s, Taiwan has shifted to being a net CO2 emissions exporter. The share of Taiwan's CO2 emissions exported to developed countries has decreased. However, the share exported to Mainland China, Hong Kong special administrative region and many developing countries in Southeast Asia has increased. The results of a structural decomposition analysis show that emissions intensity changes were the main driving force for Taiwan's exported CO2 emissions during 1970–1996, while increased export volumes were the largest driving force for Taiwan's exported CO2 emissions during 1996–2015. Emissions intensity changes and population growth are the main driving factors for Taiwan's CO2 emissions produced and consumed by itself increases. Based on the SDA results, environmentally friendly policies, such as energy efficiency and industrial structure optimization, are suggested to help Taiwan shift towards a sustainable economy.

Cities play an important role in carbon emissions reduction and climate change mitigation. In this study, we examine the CO2 emissions embodied in the imports and exports of the Hong Kong special administrative region (SAR) from 1990 to 2015 using the emissions embodied in bilateral trade (EEBT) method. The results show that Hong Kong SAR has been a net CO2 importer and Mainland China plays a dominating role in the embodied CO2 emissions of Hong Kong SAR. The sectors with high imported CO2 emissions are mainly the energy sectors, such as electricity, heat, gas and water production and supply. Population density, GDP per capita, and trade openness have significantly positive effects on net CO2 emissions increases in Hong Kong SAR, with population density taking the leading role. Population density increases by 1%, total net CO2 emissions increase by 4%. Population slowdown scenario simulation results show that net CO2 emissions of Hong Kong SAR could be reduced by 5.5%. Whereas, net CO2 emissions of Hong Kong SAR could increase by 8.7% in the accelerated economic development scenario. Therefore, to reduce CO2 emissions, Hong Kong SAR need control its population, develop the circular economy, and promote green lifestyle and consumption patterns.

CO2 emissions caused by household consumption have become one of the main sources of greenhouse gas emissions. Studying household CO2 emissions (HCEs) is of great significance to energy conservation and emissions reduction. In this study, we quantitatively analyzed the direct and indirect CO2 emissions by urban and rural households in Beijing, Tianjin, Shanghai, and Chongqing. The results show that urban total HCEs are larger than rural total HCEs for the four megacities. Urban total per capita household CO2 emissions (PHCEs) are larger than rural total PHCEs in Beijing, Tianjin, and Chongqing, while rural total PHCEs in Shanghai are larger than urban total PHCEs. Electricity and hot water production and supply was the largest contributor of indirect HCEs for both rural and urban households. Beijing, Tianjin, Shanghai, and Chongqing outsourced a large amount of indirect CO2 emissions to their neighboring provinces.

CO2 and SO2, while having different environmental impacts, are both linked to the burning of fossil fuels. Research on joint patterns of CO2 emissions and SO2 emissions may provide useful information for decision-makers to reduce these emissions effectively. This study analyzes both CO2 emissions and SO2 emissions embodied in interprovincial trade in 2007 and 2010 using multi-regional input–output analysis. Backward and forward linkage analysis shows that Production and Supply of Electric Power and Steam, Non-metal Mineral Products, and Metal Smelting and Pressing are key sectors for mitigating SO2 and CO2 emissions along the national supply chain. The total SO2 emissions and CO2 emissions of these sectors accounted for 81% and 76% of the total national SO2 emissions and CO2 emissions, respectively.

CO2 emissions embodied in trade have an important and far-reaching impact on CO2 emissions reduction obligations. Based on a multi-regional input-output analysis, this paper calculates China’s provincial CO2 emissions embodied in trade and analyzes CO2 emissions embodied in trade per unit of value of trade in 30 Chinese provinces. Several climate policy options that potentially reduce the impact of trade on individual provinces are discussed. One finding from this study is that provincial CO2 emissions embodied in trade accounted for approximately 60.02% of China’s CO2 emissions in 2007. The CO2 emissions embodied in imports and exports for 30 Chinese provinces differ widely, and remarkable differences in the CO2 emissions embodied in trade per unit of value of trade exist. Another important finding is that if provinces take binding commitments as a part of a coalition, instead of as individual provinces, then the impacts of trade can be reduced. Notably, however, the extent of reduction in a coalition varies in different provinces.
