MEIC published the inventory of anthropogenic air pollutants and CO2 emissions in China from 1990 to 2020

MEIC improved the long-term time series of the integrated emission inventory for anthropogenic sources of atmospheric pollutants and CO2 in China from 1990 to 2020, supporting the coordinated control of air pollution and climate change and the synergy of pollution reduction and carbon reduction.

MEIC published the global multi-scale dynamic CO2 emission database

Tsinghua University cooperates with the team of China Emission Accounts and Datasets (CEADs), Chinese Academy of Environmental Planning of the Ministry of Ecology and Environment, and other research groups, to develop MEIC database to meet the needs of global climate and air pollution research. MEIC builds a global multi-scale atmospheric emission database with long time series, high spatial and temporal resolution, and dynamic updates.

The Multi-scale Emission Inventory Reanalysis and Data Sharing Platform online!

Recently, a multi-scale emission inventory reanalysis and data sharing platform independently developed by the MEIC team of Tsinghua University was launched on the MEIC website. Emission inventories from multiple research groups are shared on the Data Platform, including Tsinghua University, Peking University, Nanjing University, Jinan University, Beijing University of Technology and Shanghai Academy of Environmental Sciences.

MEIC team reveals the key drivers of PM2.5 air pollution deaths in China 2002–2017

Emission controls avoided some 870,000 deaths in China between 2002 and 2017 but further air quality improvements need energy–climate policies and changed economic structure, according to index decomposition analysis and chemical transport models.

MEIC team published China’s emission inventories in 2019 and 2020 to assess the impact of COVID-19 on China’s emissions

The COVID-19 lockdown has reduced China’s anthropogenic emissions substantially between January and March in 2020, with the largest reductions in February. Emissions of SO2, NOx, CO, NMVOCs, and primary PM2.5 were estimated to have decreased by 27%, 36%, 28%, 31%, and 24%, respectively, in February 2020 compared to the same month in 2019.
