Constituent entities which make up Russia have wide-ranging powers and are considered as important policymakers and implementers of climate change mitigation. Formulation of CO 2 emission inventories for Russia's constituent entities is the priority step in achieving emission reduction. Russia is the world's largest exporter of oil and gas combined and the fourth biggest CO 2 emitter, so it's efforts in mitigating CO 2 emissions are globally significant in curbing climate change. However, the existing emission inventories only present national CO 2 emissions; the subnational emission details are missing. In addition, the emission factors are not country-specific and energy activity data by fossil energy types and sectors are not sufficiently detailed. In this study, the CO 2 emission inventories of Russia and its 82 constituent entities from 2005 to 2019 are constructed. The emission inventories include energy-related emissions with 89 socio-economic sectors and 17 energy types and process-related emissions. The uniformly formatted emission inventories can be a reference for in-depth analysis of emission characteristics and emission-related studies of Russia., (© 2021. The Author(s).)

As the world's largest CO2 emitter, China's emission reduction is the key to mitigating global climate change. Global investment capital, as a significant influencing factor of emissions, greatly contributes to China's economic growth and stimulates frequent interprovincial trade since the reform and opening. However, the spatial correlation of foreign investment and CO2 emissions across Chinese provinces is rarely considered. This paper explores the role of foreign direct investment (FDI) in emission reduction in China during 2004–2015 using the spatial Durbin economic models with two‐way fixed effects. Then, the partial differential equations decomposition of the local and spatial spillover effects is conducted for capturing the marginal effects of influencing factors. Results show that FDI contributes to emission reduction for the whole country, whereas interprovincial transmission and intra‐provincial transmission show significant heterogeneity. Specifically, FDI increases emissions in host areas, while FDI provides positive environmental externalities to adjacent areas through spatial spillovers. Our findings provide a new perspective to explain the coexistence of the "Pollution Haven" and "Pollution Halo" theories in a country. Also, the exploration of spatial spillover effects of FDI on emissions can provide a reference for other countries with rising trade and investment flows to promote collaborative emission reduction. Key Points: Local effects of foreign direct investment on emissions are positive, while spatial spillover effects are negativeThe coexistence of the "Pollution Haven" and "Pollution Halo" theories in a country is examinedResults help promote collaborative emission reduction across regions with trade [ABSTRACT FROM AUTHOR]

To put the brakes on global climate change, China, the world's top emitter, has established ambitious CO 2 emissions reduction targets. Industry-level emissions analysis can help policymakers determine better ways to achieve mitigation targets. This study is the first to target the total-factor carbon emission performance (TCPI) of secondary and service industries. We first compile industry-level CO 2 emission inventories of 25 Yangtze River Delta cities during 2007–2016. The TCPI of secondary and service industries is then estimated by the non-radial directional distance function. We then compare the TCPI of the two industries across levels, dynamics, and inequalities using a global metafrontier approach. The results show the TCPI of the service industry (0.563 in 2016) was significantly higher than that of secondary industry (0.256 in 2016), suggesting that the service industry was more carbon-friendly. The TCPI gap between the secondary and service industries narrowed over the study period. The TCPI of secondary industry showed a promising increase during 2007–2016 with an annual growth rate of 2.30%, reflecting the positive effects of the government's reforms and environmental regulations. By contrast, the service industry saw a downward trend in TCPI, decreasing by 1.68% annually, primarily because it is a newcomer to low-carbon development. TCPI inequality in secondary industry was much larger than in the service industry, suggesting that significant heterogeneity exists in secondary industry. Therefore, policymakers should implement targeted mitigation policies for secondary industry, and place decarbonising the service industry on the agenda to reverse its decreasing TCPI. Image 1 • Carbon emission performance of secondary and service industries is investigated. • Service industry is more carbon-friendly than secondary industry. • The gap in carbon emission performance between secondary and service industries narrows. • Secondary industry has greater heterogeneity of carbon emission performance than service industry.
