Introduction of GID-Cement Emission Database (GID-GCED) ：

The GID-Cement Emission Database (GCED) provides CO2 and air pollutant emissions as well as underlying information of global cement plants. GCED is based on the integration of global and regional cement plant database such as the Global Cement Directory (Global Cement, 2020) and the IndustryAbout database (IndustryAbout, 2019). We compiled, combined, and harmonized the available data related to cement production kilns from database described above, and filled data gaps with modelled emissions.

The GCED provides up-to-date elementary information and high-resolution emissions from global cement plants, which includes plant-level, national, and regional capacity and age information, as well as anthropogenic emissions of CO2 and various air pollutants (SO2, NOX, primary PM, VOCs, CO, black carbon, and organic carbon). For elementary information which is obtained from collaborators’ database and restricted by user’s license (e.g., Global Cement), we provide cross-links to the original database. Users can purchase the relevant database and merge with GCED to get complete information at plant level.

The GCED v1.0 includes a consistent time series of emissions and underlying information for global cement plants by integrating several global and regional databases. The GCED v1.0 is based on the Global Cement Directory (Global Cement, 2020) and the IndustryAbout database (IndustryAbout, 2019) to compile the basic operational information of cement kilns, and calibrated by local database in China (Liu et al., 2021). The current GCED v1.0 dataset provides company ownership, plant name, plant location, number of production kilns, capacity, and process- and fuel-based emissions in 2019 for each cement plant, where the underlying information at plant level were obtained from the Global Cement Directory and the IndustryAbout database. GCED v1.0 dataset also provides summary of capacity and age distribution by country and by region, in which China’s data were calibrated by the local database developed by Liu et al. (2021). Emissions of air pollutants and emissions for other years will be available once they are finished.

The GID team will timely update air pollutants and carbon dioxide emission inventory and continuously provide high-quality data products by integrating more high-resolution local datasets. If you are looking for more detailed emissions and potential collaboration, please contact us.
