Abstract ：
Carbon emission efficiency, which is mainly affected by economic output, energy efficiency and energy structure, is the effect of carbon emissions generated in economic activities. Improving carbon emission efficiency and narrowing regional differences are very important for green development in Belt and Road Initiative regions with developing countries as the main body. The existing literature mostly uses the Theil index to study the temporal differences in carbon emission efficiency, but spatial differences and the reasons for the differences have rarely been examined. This paper measures the differences of carbon emission efficiency using the Theil index and examines the reasons based on the Logarithmic Mean Divisia index (LMDI) method in five groups of 60 Belt and Road Initiative countries. The results show that the Theil index of carbon emission efficiency in these countries is 0.196, with an intra-group difference of 0.165 and an inter-group difference of 0.031. Between most of the groups, energy efficiency is the dominant factor affecting carbon emission efficiency differences, especially between East Asia and Central and Eastern Europe, South Asia and East Asia. Between most of the countries with the highest and lowest carbon emission efficiency in the same group, such as Singapore and Vietnam in East Asia, energy efficiency is still the primary factor affecting the differences. Only some differences between a few groups, countries and sectors have been caused mainly by energy structures. Therefore, improving energy efficiency is the first way for those countries with low carbon emission efficiency to catch up other countries with high carbon emission efficiency, followed by improving the energy structure.

Abstract ：
China attaches great importance to international cooperation on climate change, especially working with the Belt and Road Initiative relevant partners. From a perspective on carbon emissions and economic spillover effects, this study explores how China and the Belt and Road Initiative countries can work together to cope with climate change. It applies a three-region spillover effects model, based on the multi-regional input-output table and satellite extensions data of the Eora database, to examine mutual carbon emissions and economic spillover effects between China and the Belt and Road Initiative countries. The results show that: (1) Mutual carbon emissions spillover effects exist between China and the BRI countries, which is an important premise for them to cooperate responding to climate change. (2) There are great differences in carbon emission spillover effects among different sectors. Thus, optimizing the trade structure can bring benefits to carbon reduction for both sides. (3) The sectoral order of carbon emissions spillover effects, and economic spillover effects, is not consistent. In order to achieve an economic and environmental win-win, it is necessary to increase bilateral trade in those sectors with large economic spillover effects, and reduce other sectors with large carbon emissions spillover effects.

Abstract ：
Owing to global climate change and increased environmental pollution, China faces the dual responsibility of reducing CO2 emissions and controlling PM2.5 pollution. This study compares the spatial characteristics of PM2.5 concentrations and CO2 emissions using 10 km x 10 km grid data. The increase and decrease of CO2 emissions and PM2.5 concentrations are divided into four quadrants, which indicates four different conditions. Then, spatial autocorrelation method is conducted to analysis the spatial relationships. The empirical results show that (1) In the four quadrants, the increase of CO2 emissions and the decrease of PM2.5 concentrations accounted for the highest proportion (25.9%). (2) The spatial differences in CO2 emissions are large, but the PM2.5 concentrations show strong spatial aggregation. (3) China's three major urban agglomerations contain more than half of the areas in which both CO2 emissions and PM2.5 concentrations increased, and the Pearl River Delta urban agglomeration exhibits the best synergistic reduction effect. By contrast, the Beijing-Tianjin-Hebei urban agglomeration has the worst synergistic reduction of CO2 emissions and PM2.5 concentrations. (4) At the urban level, as a typical city in the Beijing-Tianjin-Hebei urban agglomeration, Tianjin's overreliance on heavy chemical industries has led to co-increases in its CO2 emissions and PM2.5 concentrations. Shaoxing and Jiangmen, in the Yangtze River Delta and Pearl River Delta urban agglomeration, are among the few cities where CO2 emissions and PM2.5 concentrations have both been reduced. Finally, this paper suggests some policy implications of these findings.

Abstract ：
This study aims to model the temporal and spatial characteristics of end-of-life (EOL) power batteries from electric vehicles (EVs) in China. A Stanford estimation model is used, assuming that the lifetime of power batteries obeys a Weibull distribution. We collected the sales data for two types of power batteries used in four types of EVs from 2009 to 2018 in mainland China and predicted the sales data from 2019 to 2030 according to the Chinese government's plan. The results present a complete picture of EOL batteries in China: (1) the generation of retired power batteries in China is predicted from 2020 to 2036, including 112 k tonnes in 2020 and 708 k tonnes in 2030; (2) the potential economic value of retired batteries for echelon and recovery utilization is analyzed; and (3) the generation of retired power batteries in 20 provinces was estimated and compared with their collection station numbers. Considering the weight of different batteries and the service life increase caused by technology upgrades, our predictions for the quantity of retired batteries are lower and more accurate than others' predictions. Large-scale battery retirement will come later than previously anticipated. We should plan the number of recycling sites in main provinces based on the accurate retired amount

Abstract ：
With the development of economy, some industries may increasingly adjust and shift between countries or regions. Industrial shifting often manifests itself in the form of investment and trade activities between relevant countries or regions. Industrial shifting also accompanies with the flow of implied energy, which ultimately affects carbon emissions. Carbon emissions are closely related to energy consumption, energy conservation and emission reduction, and have become a hot topic for scholars to study. The existence of carbon shifting has made it a controversial issue. Therefore, this paper reviews the impact of international industrial shift on China's carbon emissions, including the connotation of industrial shift, the main ways that the international industrial shift has impacts on China's carbon emissions, the way to determine such impacts, the ultimate impacts and the policy inspiration gained. It is aiming at providing theoretical support for China's goal of improving economic and environmental cooperation. © 2019, China National Chemical Information Center. All right reserved.

Abstract ：
Energy consumption plays a significant role in the integration process of Beijing- Tianjin-Hebei economic belt. This paper compares energy situation of Beijing-Tianjin-Hebei economic belt and Tokyo-to metropolitan area. The results show there are some differences between Beijing-Tianjin-Hebei economic belt and Tokyo-to metropolitan area: first, the proportion of Beijing-Tianjin-Hebei economic belt in China is lower than the proportion of Tokyo-to metropolitan area in Japan; second, energy intensity of Beijing-Tianjin-Hebei economic belt experiences a trend of descending, while it holds stable in Tokyo-to metropolitan area; third, energy structure of Beijing-Tianjin-Hebei economic belt has a serious reliance on coal, whereas, in Tokyo-to metropolitan area, consumption of oil took the main proportion of energy structure, consumption of renewable energy increasing constantly. Based on our findings, we present some policy implications for energy save in Beijing-Tianjin-Hebei economic belt. © Published under licence by IOP Publishing Ltd.

Abstract ：
Using waste cooking oil for biofuel production is potentially beneficial to food safety and energy supply. However, the lack of waste cooking oil as a feedstock for biofuel production is one of the main reasons mentioned by the biofuel industry for the illegal reprocessing of cooking oil for secondary use. Thus, it is necessary to acquire information and knowledge about how to inspire restaurants to submit their wasted cooking oil to formal collectors such as biofuel manufacturers, rather than to informal channels. We carry out random sampling surveys on restaurants in Beijing's urban districts through interne questionnaires and face-to-face investigations to explore the behaviours, awareness, and willingness of restaurants to submit their waste cooking oil for biofuel production. The results show that the total quantity of waste cooking oil generated by restaurants is 90.14 thousand tonnes in 2016. Additionally, 24% of restaurants do not submit waste cooking oil to formal collectors, and approximately 21.63 thousand tonnes of waste cooking oil is unaccounted for. We find that mandatory regulations and economic incentives are the dominant factors that affect restaurants' disposal decisions. With a subsidy value of 4 yuan RMB/kg, all the restaurants are willing to submit waste cooking oil to formal collectors. Governmental departments should also consider building economic incentives, enhancing the mandatory regulation, designing different methods to manage different types of restaurants, and strengthening supervision and education to ensure the safe disposal of waste cooking oil and promote its use for biofuel production.

Abstract ：
In this work, we demonstrate the application of water vapor doped indium oxide, alloyed with transition metal element M (IMO), as highly transparent conductive oxide (TCO) films incorporated in bifacial silicon heterojunction (SHJ) solar cells. By adding water vapor and oxygen gas into sputtering gas mixture, both electrical and optical properties of IMO film can he improved significantly. IMO films are characterized by sheet resistivity, Hall mobility and carrier density, crystallinity, and spectral transmittance. Finally, we obtained a 0.64 mA/cm(2) gain in J(SC) with optimal water vapor doped IMO film on n-side of SHJ cell, resulting in a 0.31% increase in solar cell conversion efficiency.

Abstract ：
Interregional trade not only contributes to economic output but also causes a large amount of CO2 emissions. We measure the spillover and feedback effects of economy and CO2 emissions in the capital city agglomeration of China by a four-region input-output model. The results reveal that the contribution of spillover effects on both economic output and CO2 emissions is remarkable. First, both of net economic and CO2 emissions spillovers flow from Beijing to Hebei and Tianjin. Second, net economic spillovers flow from Hebei to Tianjin, however net CO2 emissions spillovers flow from Tianjin to Hebei. Thirdly, there are some sectors, such as mining and washing of coal sector, whose economic and CO2 emissions net spillovers flow in opposite directions between any two cities. The results indicate that the economic driving function from Tianjin to Hebei needs to be strengthened, and Tianjin should assume part of the CO2 emissions responsibility for Hebei. The most important is that cities should work together to replace coal with clean energy technologies such as those based on wind and solar.
