Summary: This study used an environment extended input-output model to calculate the aggregate embodied carbon intensity (AECI) of Shanxi Province in different years and analyze its contributors and drivers. The results showed that outflow to other provinces became the primary contributor to AECI change after 2012, and the sectors of electricity, construction, mining, and metallurgy contributed the most to AECI. The main driver of AECI change shifted gradually from energy intensity to production structure and final demand factors.

Summary: This paper investigates the decoupling between economic growth and energy consumption in various sectors of the Chinese economy from 1995 to 2015. It found that China experienced weak decoupling followed by strong decoupling in its sectors, with changes mainly occurring due to financial crises, international trade growth, and less energy consumption. The production effect was identified as a positive driving factor for decoupling, while the energy intensity effect played a negative role.

Summary: This paper uses China's input-output table and structural decomposition analysis to identify the main driving factors affecting renewable energy utilization, including changes in consumption structure, technological progress, and per capita final demand. The supply of electric power, heat power, and water, as well as the manufacture of coke and refined petroleum products, are identified as the crucial sectors for achieving energy transition at the production level. However, the proportion of renewable energy has been declining at the household level, indicating the need for government intervention to promote green transitions.

Summary: This study analyzed and compared the patterns of embodied agricultural carbon emissions (ACE) in China and the United States using a multi-regional input-output model. The findings showed that ACE associated with imports and exports in both countries increased and then decreased over time. The reduction in ACE was attributed to the declining intensity of ACE per unit of traded products and the diminishing proportion of the primary industry.

Summary: This study constructs a dynamic energy input-output model to analyze the embodied energy flows and stocks from 2000 to 2014. The results show that the global fixed capital stock stored a significant amount of embodied energy, which was three times the world's direct energy use. The gaps between the dynamic energy footprints and the traditional ones were larger in fast-developing countries. Net embodied energy usually flowed from high-intensity economies to lower-intensity economies.

Summary: The Chinese experience in economic development and environmental protection serves as an important reference for other developing countries. However, there is a lack of studies examining the changes in nitrogen oxide (NOx) emissions and intensity in China. This study analyzes the socioeconomic factors and patterns behind the changes in NOx emissions and intensity, considering cleaner production and end-of-pipe treatments. The results show that the construction industry contributes the most to NOx emissions and intensity, followed by transportation. The reduction in emission intensity, achieved through end-of-pipe treatments and energy efficiency improvements, is the primary driver of NOx emissions and intensity reduction. The study also identifies the construction and building materials industry, transportation, and other services industry as critical sectors for future NOx reduction. The findings provide policy implications and recommendations for future developments.

Summary: A study finds that the imports dependency of China has decreased from 27% to 14% between 2007 and 2020, but its impact on the embodied energy consumption in final demands remains unresolved. By employing environmentally extended input-output analysis and structural decomposition analysis, this research explores the effects of import changes. At the national level, the input imports effect contributes about 15% to the growth of embodied energy consumption, while the demand imports effect contributes no more than 5%. At the sectoral level, the input imports effect occurs mainly through the metals sector from the supply side, but mainly through the electrical and optical equipment sector from the demand side. The study also identifies critical supply chains that can facilitate the input imports effect, and highlights the sectors through which the demand imports effect primarily occurs.

Summary: The aim of this study is to explore the relationship between green technology R&D investment and corporate performance, using a threshold regression model on 44 Beijing-listed energy companies from 2016 to 2021. The results indicate an inverse W-shaped nonlinear relationship between green technology R&D investment and firm performance, suggesting a positive effect within an appropriate investment interval and a negative effect outside this interval. The study also examines the impact of three threshold variables (firm size, capital structure, and capital density) on this relationship, finding optimal intervals for each variable. Furthermore, the study reveals a lagged effect of green technology R&D investment intensity on firm performance, with the positive influence weakening over time and the negative influence becoming more prominent.

Summary: Structural decomposition analysis (SDA) is a well-known approach for studying the factors contributing to changes in aggregate indicators in energy and emissions studies. This paper proposes an additive SDA framework and a multiplicative SDA framework that incorporate monthly data to reveal the drivers of temporal dynamics in energy/emissions embodiments and aggregate embodied intensity indicators. An empirical study conducted using China's 2018 and 2020 input-output tables shows that the increased granularity of data helps reveal temporal dynamics mechanisms that would otherwise be overlooked.

Summary: This paper examines the response of urban and rural residents in a China's northwestern province to temperature changes in terms of electricity consumption, and uncovers its impact on daily electricity consumption inequality between these two groups. The study findings show that the urban response function exhibits a U-shaped distribution, while that of rural residents demonstrates a fluctuating upward trend. When the daily mean temperature falls below 24°C, the gap between urban and rural electricity consumption increases. During the Spring Festival, the negative effects of extremely low temperatures will be reduced, while at the end of October, they will be increased.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
