CCED dataset

Overview >

CCED(China Cement Emission database)is an emission inventory database for China’s cement industry. The database is developed based on intensive unit-based information on activity rates, production capacity, operation status, PM and NOx control technologies for over  3100 clinker production lines and over 4500 cement grinding stations.CCED currently provides emissions of SO2、NOx、PM2.5、PM10、CO  and CO2 emissions for years in 1990-2015. The spatial distribution of shipping emissions data (NOx for example) is as follows:
