We present a high-resolution global emission catalogue of COinline-formula2 and co-emitted species (NOinline-formulax, SOinline-formula2, CO, CHinline-formula4) from thermal power plants for the year 2018. The construction of the database follows a bottom-up approach, which combines plant-specific information with national energy consumption statistics and fuel-dependent emission factors for COinline-formula2 and emission ratios for co-emitted species (e.g. the amount of NOinline-formulax emitted relative to COinline-formula2: inline-formula M10inlinescrollmathml chem normal NO x / normal CO normal 2 51pt14ptsvg-formulamathimg4d5d87fb46af9354a2cfbaf5ec4bb6ce essd-16-337-2024-ie00001.svg51pt14ptessd-16-337-2024-ie00001.png ). The resulting catalogue contains annual emission information for more than 16 000 individual facilities at their exact geographical locations. Each facility is linked to a country- and fuel-dependent temporal profile (i.e. monthly, day of the week and hourly) and a plant-level vertical profile, which were derived from national electricity generation statistics and plume rise calculations that combine stack parameters with meteorological information. The combination of the aforementioned information allows us to derive high-resolution spatial and temporal emissions for modelling purposes. Estimated annual emissions were compared against independent plant- and country-level inventories, including Carbon Monitoring for Action (CARMA), the Global Infrastructure emission Database (GID) and the Emissions Database for Global Atmospheric Research (EDGAR), as well as officially reported emission data. Overall good agreement is observed between datasets when comparing the COinline-formula2 emissions. The main discrepancies are related to the non-inclusion of auto-producer or heat-only facilities in certain countries due to a lack of data. Larger inconsistencies are obtained when comparing emissions from co-emitted species due to uncertainties in the fuel-, country- and region-dependent emission ratios and gap-filling procedures. The temporal distribution of emissions obtained in this work was compared against traditional sector-dependent profiles that are widely used in modelling efforts. This highlighted important differences and the need to consider country dependencies when temporally distributing emissions. The resulting catalogue (https://doi.org/10.24380/0a9o-v7xehttps://doi.org/10.24380/0a9o-v7xe, Guevara et al., 2023) is developed in the framework of the Prototype System for a Copernicus COinline-formula2 service (CoCO2) European Union (EU)-funded project to support the development of the Copernicus COinline-formula2 Monitoring and Verification Support capacity (CO2MVS).
