“…With the rapid increase in the global population and fast-growing industries, carbon dioxide emissions into the atmosphere are rising, and problems such as the greenhouse effect, ocean storms, land desertification and climate extremes are becoming increasingly serious (Mora et al , 2018; Jia et al , 2021; Sun and Li, 2021). Therefore, the question of how to reduce carbon dioxide emissions has become a key concern for the international community and relevant governments (Zhang and Da, 2015; Zhao et al , 2021). The report “Global Energy Review: CO 2 Emissions in 2021” released by the International Energy Agency (IEA) states that global CO 2 emissions from the energy sector reached 36.3 billion tons in 2021, growing at a 6% year-on-year pace (IEA, 2021).…”

Purpose Although the tasks of managing carbon peaks and achieving carbon neutrality in China are arduous, they are also of great significance, which highlights China’s determination and courage in dealing with climate change. The power industry is not only a major source of carbon emissions but also an important area for carbon emission reduction. Thus, against the backdrop of carbon neutrality, understanding the development status of China’s power industry guided by the carbon neutrality background is important because it largely determines the completeness of China’s carbon reduction promises to the world. This study aims to review China’s achievements in carbon reduction in the electric industry, its causes and future policy highlights. Design/methodology/approach The methods used in this study include descriptive analyses based on official statistics, government documents and reports. Findings The research results show that, after years of development, the power industry has achieved positive results in low-carbon provisions and in the electrification of consumption, and carbon emission intensity has continued to decline. Policy initiatives play a key role in this process, including, but not limited to, technology innovations, low-carbon power replacement and supported policies for low-carbon transformation toward low-carbon economies. Originality/value This study provides a full picture of China’s power industry against the backdrop of low-carbon development, which could be used as a benchmark for other countries engaging in the same processes. Moreover, a careful review of China’s development status may offer profound implications for policymaking both for China and for other governments across the globe.

“…Studies have shown that public transport facilities, especially subways, can significantly improve air quality (Sun et al 2019b). Unlike motor vehicles, which emit large amounts of pollutants owing to incomplete fuel combustion, subways consume less energy and emit fewer pollutants (Zhao et al 2021). Subways also have high efficiency and do not occupy too much space on urban roads (Joen and Amekudzi 2005).…”

This study uses empirical methods to explore the relationship between subway system development and air quality in the Yangtze River Delta. We propose a new variable to measure subway development, "subway station density value," which can more accurately describe subway development than the traditional "line opening" variable. It eliminates the effects of differences in subway line length, layout, and size of the local subway system. Using this variable, we find that subway development has a significant positive impact on air quality improvement; that is, an increase in the density of subway stations is significantly associated with improved air quality. This finding provides a scientific basis for the relevant authorities to formulate the development and layout of public transport facilities. It strongly responds to previous debates on the relationship between subways and air quality. In addition, we find that urban population size, economic development level, and subway system size play moderating roles in the relationship between subways and air quality. Increasing the availability of subways can significantly improve the air quality in cities with high population sizes and economic development levels. However, as the size of a subway system increases, its effect on air quality improvement may weaken, suggesting that the development of subway systems should not be unthinkingly expanded either. Although our study has valuable findings, we must discuss several limitations further. These include restrictions in the selection of the study population, data availability, and potentially oversimplified criteria for considering the impact of urban differences. Overall, this study not only provides new theoretical and empirical perspectives for understanding and explaining how subway development affects air quality but also indicates the direction for further exploration in future studies.

“…Meanwhile, some researches have shown that there was an inverted U-shaped relationship between PM 2.5 concentrations and the economic development in socioeconomic terms ( 25 ). Extensive economic development relying on energy and resource consumption will increase pollution sources and cause deterioration of air quality.…”

BackgroundFine particulate matter (PM2.5), one of the major atmospheric pollutants, has a significant impact on human health. However, the determinant power of natural and socioeconomic factors on the spatial-temporal variation of PM2.5 pollution is controversial in China.MethodsIn this study, we explored spatial-temporal characteristics and driving factors of PM2.5 through 252 prefecture-level cities in China from 2015 to 2019, based on the spatial autocorrelation and geographically and temporally weighted regression model (GTWR).ResultsPM2.5 concentrations showed a significant downward trend, with a decline rate of 3.58 μg m−3 a−1, and a 26.49% decrease in 2019 compared to 2015, Eastern and Central China were the two regions with the highest PM2.5 concentrations. The driving force of socioeconomic factors on PM2.5 concentrations was slightly higher than that of natural factors. Population density had a positive significant driving effect on PM2.5 concentrations, and precipitation was the negative main driving factor. The two main driving factors (population density and precipitation) showed that the driving capability in northern region was stronger than that in southern China. North China and Central China were the regions of largest decline, and the reason for the PM2.5 decline might be the transition from a high environmental pollution-based industrial economy to a resource-clean high-tech economy since the implementation the Air Pollution Prevention and Control Action Plan in 2013.ConclusionWe need to fully consider the coordinated development of population size and local environmental carrying capacity in terms of control of PM2.5 concentrations in the future. This research is helpful for policy-makers to understand the distribution characteristics of PM2.5 emission and put forward effective policy to alleviate haze pollution.
