University of Michigan School for Environment and Sustainability Associate Professor Ming Xu and Research Fellow Shen Qu have been working with collaborators in China to develop a high-resolution spatial emission database for China.
The database, China High Resolution Emission Database (CHRED), includes gridded emission data with spatial resolution of 1 km and 10 km. CHRED is derived from bottom-up, facility-level point sources covering the entire Mainland China. The 1km × 1km resolution is the highest resolution among all similar datasets for point source emissions in China.
CHRED data span from 2007 to 2015 will be continuously updated. CHRED currently covers only carbon dioxide (CO2) emissions, and is in the process of including more types of emissions. CHRED is available free of charge for non-commercial uses through the Chinese Environmentally Extended Input-Output (CEEIO) database (www.ceeio.com).
A paper describing the development of CHRED has recently been published in the journal of Resources, Conservation & Recycling (https://doi.org/10.1016/j.resconrec.2017.10.036).
CHRED is developed in partnership with Chinese Academy of Environmental Planning and Beijing Normal University. Prof. Xu and Dr. Qu were partially supported by the Lieberthal-Rogel Center for Chinese Studies at the University of Michigan.
