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.
MEIC team developed China’s Cement Emission Database (CCED) to help low-carbon transformation and air pollution reductions
From 1990 to 2015, accompanied by a 10.3-fold increase in cement production, CO2, SO2, and NOx emissions from China’s cement industry increased by 627%, 56%, and 659%, whereas CO, PM2.5 and PM10 emissions decreased by 9%, 63%, and 59%, respectively.
