Summary: Emissions of organic compounds have significant impacts on the environment. Previous emission inventories focused on only a portion of these compounds, neglecting the contribution of semivolatile and intermediate volatile organic compounds to organic aerosol burden. This study developed a comprehensive emission inventory for China from 2005 to 2019, revealing changes in the sources and formation potential of organic aerosols. Findings indicate a decline in emissions of low/extremely low/ultralow VOC and SVOC after 2014, while emissions from volatile chemical products increased significantly and became the dominant source. These results highlight the importance of considering VCP, residential biomass burning, and diesel vehicles in future air pollution control policies.

Summary: Understanding fossil-fuel/food production and consumption patterns is crucial for reducing associated methane emissions. This study develops a comprehensive industrial-chain model, CH4-CHINA, to track CH4 emissions in China from production to disposal. The estimated national CH4 emissions in 2020 are 39,288.3 Gg, with 50.4% and 49.6% generated from fossil-fuel and food systems, respectively. The study highlights previously ignored emission sources and provides insights for effective CH4 emission mitigation strategies.

Summary: Emission regulations in power and industry sectors drove PM2.5 mitigation in China from 2013-2017, while more stringent policies in industrial, transportation, and residential sectors under the 2018-2020 protection plan accelerated air quality improvement, with reductions >30% for NO2, CO, and PM2.5. Reductions in CO and PM2.5 were most pronounced in winter and North China, while reductions in NO2 were significant across regions and seasons.

Summary: China's Air Clean Plan (ACP) has effectively reduced PM2.5 concentrations and premature deaths caused by PM2.5 exposure. However, in 2020, there were still significant premature deaths associated with PM2.5 exposure. Carbon mitigation measures have also shown environmental and health co-benefits.

Summary: This study proposes a framework for estimating pollutant emissions from specific crop residue burning by combining phenological information, land use data, field investigation/statistical data, and fire detection information. The study finds that the percentage and emissions of wheat crop residue burning in each province of mainland China exhibited an increasing trend followed by a decreasing trend from 2003 to 2019. High-emission areas were mainly concentrated in central-eastern China, and the emission areas gradually shifted from south to north from April to September. The study also shows that policies prohibiting straw burning were effective in reducing the emissions.

Summary: Understanding the spatial characteristics and mutual sources of greenhouse gas and air pollutant emissions is crucial for achieving carbon neutrality and improving air quality. This study constructs a high-resolution emission inventory for China and identifies a spatial consistency between greenhouse gas and air pollutant emissions, highlighting the potential for mutual control strategies.

Summary: China's clean air actions from 2013-2020 have led to a net reduction of 2.43 Gt CO2 emissions by promoting the transformation of the country's energy system. The co-benefits of these measures far outweigh the additional CO2 emissions, signaling the significant climate benefits of tackling air pollution.

Summary: This study analyzes the impacts of emission regulations in China's cement industry and finds that while the regulations have led to reductions in particulate matter, sulfur dioxide, and nitrogen oxide, they have also resulted in an increase in carbon dioxide emissions. Interestingly, some plants have already reached the ultra-low air pollution standards set for 2020. Further analysis suggests that if small and old plants are phased out and all remaining plants adopt advanced equipment and improve fuel and energy efficiency, there is potential for even greater reductions in air pollutants and carbon dioxide emissions.

Summary: The study found that rice grain consumption is a primary pathway of human mercury exposure. Atmospheric mercury deposition was identified as the main source of total mercury in Chinese rice grain, while soil mercury contributed significantly to methylmercury concentrations. Spatial variations in soil organic matter were found to impact the methylation potential of mercury among grids.

Summary: This study focused on measuring start emissions of gaseous pollutants and solid particle number from gasoline light-duty passenger vehicles in China, with a particular emphasis on the impact of cold-start conditions. The results showed that cold-start phase contributes significantly to total tailpipe emissions, and that emissions vary by pollutant, vehicle technology, and environmental conditions. The study also revealed seasonal, diurnal, and spatial variabilities in LDPV emissions, providing valuable insights for emission inventory and air quality simulation improvements.

Summary: Solid fuels used for cooking, heating, and lighting are significant sources of air pollutants, causing adverse environmental and health impacts. Transitioning to cleaner energy sources can result in substantial health benefits. Recent research has focused on emissions from the residential sector and their impact on air quality, population exposure, and health consequences, identifying major challenges and future research priorities.

Summary: The COVID-19 pandemic led to significant reductions in air pollutants and CO2 emissions in eastern China, with reductions dominated by power and heavy industry sectors for SO2 and CO2, and by mobile sources and light industry sectors for NOx and NMVOCs, respectively. Differentiated emission control strategies should be implemented for various source categories to achieve coordinated reduction goals.

Summary: According to the study, China can achieve its near-term climate goals by 2030 through fulfilling its National Determined Contributions (NDC) pledges and continuing air pollution control policies. However, reducing PM2.5 exposure to below 10 μg/m3 for the majority of the Chinese population by 2060 may require more ambitious climate mitigation efforts, such as China's carbon neutrality goals and global 1.5 degrees C-pathways. The research highlights the critical role of China's carbon neutrality goals in reducing air pollution exposure to the level of the World Health Organization guidelines and protecting public health.

Summary: The study found that emission controls avoided approximately 870,000 deaths in China between 2002 and 2017, but further improvements in air quality require energy-climate policies and changes in economic structure. Analysis showed that end-of-pipe control policies significantly reduced PM2.5-related deaths in China, with mandated emission control technologies avoiding nearly three-quarters of the deaths that would have occurred due to increased economic activity.

Summary: The emissions concentrations at iron- and steelmaking plants in China have decreased since the implementation of stricter standards in 2015, with particulate matter and SO2 emissions significantly reduced and NOx emissions slightly increased despite an increase in production. If all facilities meet the ultralow emission standards, emissions of particulate matter, SO2, and NOx are expected to decrease further.

Summary: China, as the largest cement producer and consumer in the world, has experienced significant increases in CO2, SO2, and NOx emissions from the cement industry from 1990 to 2015. However, the introduction of advanced technologies and policy measures has helped in reducing air pollutant emissions, particularly SO2, CO, and PM emissions, while CO2 emissions continue to rise, posing challenges to carbon emission mitigation in the future.
