“…Total energy consumption increased from 54 million tons of coal equivalent (Mtce) in 1953 to 4,299 Mtce in 2015, and the proportion of coal consumption decreased from 94.3% to 63%. In 2015, the coal consumption from thermal power, heating, industrial boiler, and resident was 17.93, 2.4, 9.08, and 0.93 Mt, respectively, which is basically consistent with statistical data from Shan et al (2018). The missing data in the early years were estimated by per capita gross domestic product (GDP).…”

Studies reporting the historical trends of SO 2 , NO x , CO, and nonmethane volatile organic compounds emissions in China using unified approaches and sources are limited. Here we established 66-year emission trends of these four species in China. Six primary anthropogenic sources were included, and we made a series of improvements to the few existing inventories based on detailed statistical data, recently published emission factors, and technology renewal to reduce the uncertainties. National SO 2 , NO x , CO, and nonmethane volatile organic compounds emissions in 2015 were 27.1, 20.6, 188, and 28.4 Mt, with annual growth rates of 5.8%, 5.9%, 3.8%, and 4.6% since 1949, respectively. In recent years, fossil fuel combustion was the major contributor to SO 2 , NO x , and CO emissions, whereas industrial process contributed most to VOCs emissions. Our results revealed a 10% decrease in the SO 2 emissions from 2005 to 2010 as a result of improvements in the flue gas desulfurization installation rate. NO x emissions stopped rising and started falling in 2011, with technology renewal and the penetration of end-of-pipe control measures in industrial boilers and cement production. Furthermore, we calculated future speciated VOCs emissions and ozone formation potential under alternative policy scenarios and projected to reduce emissions by 10% (compared with 2013 levels) with stringent control measures in 2020. A reactivity-based control strategy was proposed to achieve greater ozone formation potential reductions while requiring less VOCs emissions reduction. Plain Language SummaryOver past half century, the emissions of air pollutants generated through human activities in China have increased rapidly. The study of long-term emissions trends will improve our understanding of human influence on climate change and air quality. Here we established 66-year emission trends of four major species for the first time and evaluated the impact of government policy on emission. The central government initialed the most stringent ever action plan in China to cut emissions, for example, from 1 January 2018, China began to levy environmental protection tax, aimed at SO 2 , NO x , CO, VOCs, and other pollutants. Our result reveals a decrease in the SO 2 and NO x emissions, consistent with satellite observation, while VOCs emissions continued to rise. The emission-based reduction plan for VOCs have been implemented nationwide. In this study, we further proposed a reactivity-based control strategy to improve the air quality more effectively.SUN ET AL.

Water-energy nexus in a city can either prompt or undermine its development. Yet in China, the relevant research is rarely found. This study accounts the city-level water-energy nexus in Beijing-Tianjin-Hebei region in 2012 from both production and consumption perspectives, where input-output analysis based on city-level input-output tables are applied to conduct consumption-based accounts. Regarding water for energy, Beijing, Tianjin and Tangshan occupy the largest amounts of water for production in the energy sector, at 203 million tonnes (Mt), 148 Mt and 118 Mt, and they also consume most water for energy, at 6690 Mt, 1328 Mt and 1476 Mt. In terms of energy for water, Shijiazhuang and Tianjin have the largest amounts of CO2 emissions for production and consumption respectively, at 28 thousand tonnes (Kt) and 1746 Kt. Furthermore, local authorities should prioritise electricity sector as it holds 69% and 72% of the total water amounts for production and consumption in the energy sector. Besides, integrated management is crucial for cities with low water and energy efficiency (Baoding and Zhangjiakou), and for large CO2 emitters in Hebei province in order to ensure their water and energy sustainability without stunting their economic growth.

“…[5][6][7] Despite significant challenges to reducing emissions as an emerging economy with a huge population, China has formulated a series of effective policies to mitigate climate change through analyzing the forces driving its rapidly increasing emissions. 8 Thus, China's CO 2 emissions have plateaued since 2012, [9][10][11] as its economic development has entered a stage named ''the new normal.'' 12 Development patterns are shifting from rapid growth to sustained growth in this new stage with a more inclusive and sustainable economic structure, including higher living standards, cleaner energy industries, and more knowledge-based services.…”
