EDGAR (Emissions Database for Global Atmospheric Research) is a global inventory that compiles greenhouse gas and air pollutant emissions to support climate science, environmental policy, and international assessment. It provides gridded, sectoral and species-resolved data used by researchers, policymakers and agencies involved in atmospheric chemistry, energy transitions and international negotiations. EDGAR interfaces with major institutions in climate research and environmental assessment and contributes to databases used by intergovernmental bodies and academic consortia.
EDGAR aggregates anthropogenic emissions for gases and aerosols across sectors and regions, linking to datasets used by Intergovernmental Panel on Climate Change, European Commission, United Nations Framework Convention on Climate Change, World Meteorological Organization, and academic centers such as Max Planck Institute for Meteorology, University of Cambridge, Massachusetts Institute of Technology, Stanford University, and Imperial College London. The inventory spans long-lived species like carbon dioxide and methane and short-lived climate forcers referenced in reports by Tyndall Centre, National Aeronautics and Space Administration, European Space Agency, Potsdam Institute for Climate Impact Research, and International Energy Agency. EDGAR outputs underpin assessments by Global Carbon Project, International Panel on Climate Change Working Group I, World Bank, Organisation for Economic Co-operation and Development, and regional bodies such as European Environment Agency.
EDGAR methodology evolved through collaboration with institutes including Joint Research Centre, Netherlands Environmental Assessment Agency, Centre for Ecology & Hydrology, CNRS, and Karlsruhe Institute of Technology. Emission factors and activity data derive from national inventories, sectoral studies and international datasets maintained by United Nations Environment Programme, Food and Agriculture Organization, International Maritime Organization, International Civil Aviation Organization, and International Energy Agency. Spatial allocation uses proxies from gridded datasets such as GRUMP, Landscan, Global Human Settlement Layer, and remote sensing products from MODIS and Sentinel-2, often integrated with economic data from World Bank and United Nations Statistical Division.
EDGAR provides time series, gridded maps, sectoral breakdowns and speciation for gases and aerosols compatible with modelling frameworks employed by Community Earth System Model, ECMWF, WRF-Chem, GEOS-Chem, and HadGEM. Species include carbon dioxide, methane, nitrous oxide, sulfur dioxide, nitrogen oxides, black carbon and organic carbon, with sector tags such as energy production, transport, industry, agriculture, waste and shipping tied to classifications used in North American Industry Classification System and International Standard Industrial Classification. Products are formatted for use with tools from EPA, NASA Goddard, NOAA, Mercator Ocean, and datasets for scenario comparison with Shared Socioeconomic Pathways and Representative Concentration Pathways.
EDGAR is used in climate modelling studies by groups at Met Office Hadley Centre, Lawrence Berkeley National Laboratory, Scripps Institution of Oceanography, and Columbia University for attribution, projection and policy analysis. Policymakers at European Commission Directorate-General for Climate Action, negotiators at United Nations Framework Convention on Climate Change Secretariat, financiers at World Bank Group and analysts at International Monetary Fund employ EDGAR-derived metrics for national inventories, carbon budgeting and compliance mechanisms. Urban planners in municipalities like London, New York City, Beijing, Delhi, and São Paulo use gridded emissions for air quality management alongside researchers at Harvard University, Yale University, and ETH Zurich studying health impacts and exposure.
EDGAR undergoes intercomparison with inventories from US Environmental Protection Agency, Environment and Climate Change Canada, Japanese Ministry of the Environment, and regional inventories compiled by European Environment Agency and Asian Development Bank. Atmospheric inversions using observations from networks such as ICOS, NOAA ESRL, Global Atmosphere Watch, AERONET, and satellite retrievals from OCO-2, TROPOMI, and IASI help constrain emissions and quantify uncertainty. Uncertainty estimates consider factors reported by Intergovernmental Panel on Climate Change, national statistical offices, and peer-reviewed evaluations from journals like Nature, Science, Atmospheric Chemistry and Physics, and Environmental Research Letters.
EDGAR distributes datasets through portals linked to European Commission Joint Research Centre, research data infrastructures coordinated with Copernicus Programme and cataloged in repositories such as PANGAEA and institutional archives at CERN Open Data Portal and university data centers. Licensing is aimed at open science compatible with policies from European Commission Directorate-General for Research and Innovation, Horizon 2020, Horizon Europe, and data-sharing frameworks endorsed by United Nations agencies and research funders including Wellcome Trust and National Science Foundation.
EDGAR is maintained through collaborations among agencies and research institutes including European Commission, Netherlands Environmental Assessment Agency, Joint Research Centre, Potsdam Institute for Climate Impact Research, Royal Netherlands Meteorological Institute, and academic partners like University of Oxford and University of Copenhagen. It interacts with intergovernmental processes involving United Nations Framework Convention on Climate Change, Intergovernmental Panel on Climate Change, Convention on Long-range Transboundary Air Pollution, and technical working groups from International Energy Agency and World Meteorological Organization to ensure relevance for reporting, modelling and policy support.
