China high resolution emission database (CHRED) with point emission sources, gridded emission data, and supplementary socioeconomic data

This study constructs a China High Resolution Emission Database (CHRED), including point emission sources, gridded emission data (with the spatial resolution of 1 km and 10 km), and supplementary socioeconomic data. This database responses to the growing and urgent demands of high-quality, fine-grained environmental emission data to support China's sustainable development at various spatial scales. The CHRED is derived from bottom-up, enterprise-level point sources. It covers emission sources of the whole Mainland China. It can be used for spatial analysis of emissions in China, validation and inversion of remote sensing data from carbon observation satellites, and spatially explicit environmental footprint analysis. It lays a solid foundation for studies on environmental emissions and emission mitigation policies in China.
