From 2013 to 2017, with the implementation of toughest-ever clean air policy in China, significant declines fine particle (PM2.5) concentrations occurred nationwide. Here we estimate drivers improved PM2.5 quality and associated health benefits China from 2017 based on a measure-specific integrated evaluation approach, which combines bottom-up emission inventory, chemical transport model, epidemiological exposure-response functions. The estimated national population-weighted annual mean...
Abstract. The COVID-19 pandemic lockdowns led to a sharp drop in socio-economic activities China 2020, including reductions fossil fuel use, industry productions, and traffic volumes. short-term impacts of on China's air quality have been measured reported, however, the changes anthropogenic emissions not yet assessed quantitatively, which hinders our understanding causes during COVID-19. Here, for first time, we report pollutant from mainland by using bottom-up approach based near-real-time...
Abstract Climate change mitigation measures can yield substantial air quality improvements while emerging clean in developing countries also lead to CO 2 emission co-benefits by affecting the local energy system. Here, we evaluate effect of China’s stringent actions on its use and emissions from 2013-2020. We find that widespread phase-out upgrades outdated, polluting, inefficient combustion facilities during have promoted transformation country’s The far outweigh additional end-of-pipe...
In response to the severe air pollution issue, Chinese government implemented two phases (Phase I, 2013–2017; Phase II, 2018–2020) of clean actions since 2013, resulting in a significant decline fine particles (PM2.5) during 2013–2020, while warm-season (April–September) mean maximum daily 8 h average ozone (MDA8 O3) increased by 2.6 μg m–3 yr–1 China same period. Here, we derived drivers behind rising O3 concentrations using bottom-up emission inventory, regional chemical transport model,...
Abstract. China is the largest cement producer and consumer in world. Cement manufacturing highly energy-intensive one of major contributors to carbon dioxide (CO2) air pollutant emissions, which threatens climate mitigation quality improvement. In this study, we investigated decadal changes emissions for period 1990–2015 based on intensive unit-based information activity rates, production capacity, operation status, control technologies improved accuracy China. We found that, from 1990...
Abstract A transition away from coal power always maintains a high level of complexity as there are several overlapping considerations such technical feasibility, economic costs, and environmental health impacts. Here, we explore the cost-effectiveness uncertainty brought by policy implementation disturbances different phaseout new-built strategies (i.e., disruption priority) in China based on developed unit-level assessment framework. We reveal opportunity risk decisions employing...
Abstract. Constructing a highly resolved comprehensive emission dataset for China is challenging due to limited availability of refined information parameters in unified bottom-up framework. Here, by developing an integrated modeling framework, we harmonized multi-source heterogeneous data, including several up-to-date inventories at national and regional scales key species sources generate 0.1° resolution inventory 2017. By source mapping, temporal disaggregation, spatial allocation,...
Gridded maps of CO2 emissions are increasingly being applied in emission change analyses and atmospheric studies. In this study, we compared two high-resolution gridded estimates anthropogenic Europe for 2019-2021: the near-real-time Global daily data set (GRACED, latest updated version May 2024) Copernicus Atmosphere Monitoring Service regional inventory (CAMS-REG, v6 2019-2020, v7 2021). Total sets comparable, with a 2.4% difference, total emissions' spatial determination coefficient (R)...
On-road transportation is one of the major contributors to energy consumption and CO2 emissions in global megacities, high-resolution traffic emission maps are needed analyze patterns. In this study, commercial GPS-based data provides hourly, road-specific information on vehicle speed volume, machine learning models employed address gaps transform sample counts into real flux. Combined with COPERT, we developed on-road for 10 selected cities France, Germany, Netherlands. Our analysis offered...
India, a rapidly developing economy with the world’s largest population, has set an ambitious target of achieving net-zero carbon emissions by 2070. Road transport, contributing to 12% India’s energy-related CO2 emissions, plays significant role in exacerbating urban air pollution. Given country’s swift urbanization and expansion road transport meet mobility demands, from this sector could potentially double 2050, risking achievement long-term climate...

China has pledged to peak CO2 emissions before 2030 and achieve carbon neutrality 2060, climate actions are urgently needed. Cites basic administrative units leaders in implementing emission reduction policies China, a comprehensive analysis of characteristics historical trends Chinese cities is great importance. This study developed city-level inventory during 2012-2018 by merging multiple databases. The results reveal spatial heterogeneity inequality cities’ emissions. In...
