Gridded Emissions Inventory for China's Express Delivery Transportation in 2021

This dataset contains gridded annual emissions inventory from China's express delivery transportation sector for the year 2021. The inventory was developed using large-scale waybill data (>800,000 records), geospatial modeling, and detailed calculations as described in Li et al. (2025) "Environmental burden and health inequity in China's road-based express delivery" published in Nature Cities. This dataset contains 7 GeoTIFF files representing annual emissions totals for different pollutants/GHG. Spatial Coverage and Resolution Geographic Coverage: Mainland China Spatial Resolution: 5 arcminutes × 5 arcminutes Coordinate System: WGS84 Geographic Coordinate System Units: kg/grid cell/year Temporal Coverage: Annual totals for 2021 When using this dataset, please cite: Li, B., Liao, H., Li, K., Lin, J., Gong, C., Liu, H., Li, Y., Chen, L., Yang, Y., Jin, X., Zhao, Y., Wang, T., Jin, J., Dang, R., & Jacob, D.J.
