Changes in China’s anthropogenic emissions during the COVID-19 pandemic

Posted on 21.11.2020 - 14:22 authored by Bo Zheng
We report the anthropogenic air pollutant emissions from mainland China during the first eight months of 2020 by using a bottom-up approach based on the near real-time data. We use the Multi-resolution Emission Inventory for China (MEIC) model to estimate China’s emissions in 2018 and 2019 and then use 39 types of near real-time activity data to update the emission estimates to 2020. Provincial and sectoral emissions are estimated by month and the relative changes in monthly emissions from 2019 to 2020 are compared with the satellite and ground-based observations for a preliminary evaluation.

This dataset includes the reduction ratios of China's anthropogenic emissions from 2019 to 2020 by species, sector, month, and province.
- The pollutant species include SO2, NOx, CO, NMVOCs, PM2.5, and BC.
- Four source sectors are reported: power, industry, residential, and transportation.
- January to August in 2020
- All of the 31 provinces in mainland China.
