Summary: The reduction in anthropogenic NOx emissions from motor vehicles due to emission control technologies and policies is significant but uncertain. This study evaluates a fuel-based emission inventory for southern California, finding that on-road vehicles are the main source of NOx emissions in the South Coast Air Basin. The fuel-based inventory provides different estimates of NOx emissions for different vehicle types compared to the planning inventory.

Summary: This study evaluates the concentrations and sources of air pollutants in Lhasa during August 2016 using a model and observational data. The results show that the model underestimates the air pollutant concentrations in Lhasa, with insufficient emissions being the main reason. The study suggests that local anthropogenic emissions have a significant impact on urban air quality and deserve further attention.

Summary: This study develops a high-resolution SAFAR emission inventory of BC-OC for 2011 and 2018 in India using GIS and statistical models. The transport sector is found to be the dominant contributor to BC emissions, accounting for 46%, while the residential sector is the main source of OC emissions with a 39% share. The overall growth of BC and OC emissions from 2011 to 2018 is estimated to be 32% and 36% respectively, with the transport sector showing the highest growth.

Summary: This study investigated the anthropogenic VOCs emissions in Huai'an City in 2017 and estimated the contributions of different VOC species to ozone formation. The results showed that industrial processes and solvent use were the main sources of VOCs emissions, accounting for 41% and 32% of the total emissions, respectively. The high emissions were spatially located in the areas with intensive industrial activities, highlighting the importance of considering VOC species and their effects on ozone formation in future 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: Long-term exposure to ambient PM2.5 is associated with an increased incidence of lung cancer, and this study found that it also decreases the survival rate for lung cancer patients. However, the implementation of clean air actions in Beijing has been shown to prolong the survival time of these patients by reducing PM2.5 levels.

Summary: Air pollution control policies in China have undergone significant changes, shifting from overall pollutant emission control to air quality improvement. The targets have changed from acid rain and NOx emissions to PM2.5 pollution and O-3 challenges. China has achieved remarkable success in reducing SO2 emissions and improving PM2.5 concentration, but stricter requirements for air quality and synergistic mitigation with Greenhouse Gas emissions have been proposed. Therefore, an integrated multi-objective and multi-benefit roadmap is needed to support China's long-term air quality improvement strategy.

Summary: This study quantified the contribution of pollutant emissions in 30 provinces to PM2.5 concentration and related premature mortality in China for the first time, and established a cross-province contribution matrix of health impact intensity. Based on levels of health impact intensity and carbon emission intensity, the provinces were divided into four regions. The results showed that the comprehensive assessment index was more influenced by health impact intensity, and the southeast provinces had higher environmental and climate impact per GDP.

Summary: Emission inventory is crucial for designing effective emission control strategies. However, there is an imbalance in the development of CO2 and air pollutant emission inventories in China, hindering collaborative control strategies. This study developed a unified emission inventory including both CO2 and air pollutants, and used spatial mapping methods to identify co-hotspots at a high spatial resolution. The results showed that the stationary combustion and transportation sectors were the major emitters, and the top 10% emission grids contributed the majority of the emissions.

Summary: Through studying the contributions of 155 emission sources to PM2.5-related mortality in China in 2017, we identified 25 priority-control emission sources and quantified the interprovincial ecological compensation volumes to alleviate inequality induced by emission allocation strategies. The results showed that PM2.5 pollution caused 899,443 excess deaths and around 127 billion USD costs in 2017. This study provides scientific evidence for optimizing emission allocation and compensation strategies in China and has wide implications for other countries suffering similar problems.

Summary: Clean vehicle policies will greatly benefit air quality and climate change mitigation. The study finds that due to these policies, national vehicle CO2 emissions in China will likely peak around 2028 and then decrease by 7.8% from 2028 to 2035. Most regions will experience a decrease in air pollutants emissions, leading to significant reductions in PM2.5 and O3 exposure. Approximately 68,000 PM2.5-related deaths and 33,000 O3-related deaths will be avoided nationwide from 2019 to 2035.

Summary: Extreme wildfires in boreal forests are increasing and impacting Earth's climate. These fires, which account for typically 10% of global fire carbon dioxide emissions, contributed 23% (0.48 billion metric tons of carbon) in 2021. The synchronized water deficit in North American and Eurasian boreal forests in 2021 led to the rapid expansion of wildfires, challenging climate mitigation efforts.

Summary: To monitor the effectiveness of Green Deal plan and the implementation of EU countries' pledges, Monitoring Reporting and Verification tools are necessary to track emissions changes in all sectors. The current official inventories provide annual estimates of national CO2 emissions with a lag of more than one year, unable to capture recent variations caused by events such as COVID lockdowns, economic rebounds, and the war in Ukraine. In this study, we present the Carbon Monitor Europe dataset, which provides near-real-time daily fossil fuel and cement emissions data from January 2019 to December 2021 for 27 EU countries and the UK. The dataset is divided into six sectors and aims to improve the timeliness and temporal resolution of emissions data for European countries.

Summary: Near-surface ozone pollution is one of the biggest challenges in China's air quality management. This study uses measurements from the national air quality monitoring network to analyze the spatiotemporal evolution of ozone concentrations from 2010 to 2021. The results show that the national air pollution control programme has effectively reduced ozone levels in China, with emission reductions and changing meteorological conditions playing a role. Furthermore, the effectiveness of emission controls varies by region and season, with rural areas and summer showing greater improvements. Thus, future efforts to control ozone pollution should consider these regional and seasonal variations to target the most important precursors.

Summary: Product trade plays a crucial role in redistributing production and associated air pollution impacts among different sectors and regions. However, there is a lack of a comprehensive understanding of how air pollution is redistributed through trade chains, which hampers targeted clean air cooperation. In this study, we used multiple models to track the premature deaths related to PM2.5 along supply chains in China. Our findings reveal the key sectors and regions that contribute to PM2.5-related mortality from both a production and consumption perspective, and emphasize the importance of cross-boundary effects and capital investment in driving air pollution transfer.

Summary: China is currently facing the challenges of air pollution and climate change, and the government is actively promoting the synergy between the two. The Synergetic Roadmap project was launched in 2021 to track and analyze the progress of synergetic control in China, and the 2022 report focuses on the progress in 2021 and key actions in various sectors. China's efforts in reshaping energy, economic, and transportation structures have led to a slowdown in carbon emission growth, improved air quality, and increased health benefits in recent years.
