Department of Environmental Science is responsible for the annual official Danish inventories of emissions to the atmosphere. The work is carried out through DCE – Danish Centre for Environment and Energy under contract for the Ministry of Environment and Food and the Ministry of Energy, Utilities and Climate. The inventories are reported to the European Union and international conventions, e.g. the UNECE Convention on Long-range Transboundary Air Pollution (CLRTAP) and the UN Framework Convention on Climate Change (UNFCCC).
Department of Environmental Science work continuously on improving the quality of the emission inventories and has developed models for projecting emissions. These projections include the greenhouse gases CO2, CH4 and N2O and the air pollutants SO2, NOX, NMVOC, NH3 and particulate matter. The Department has also developed a model for a detailed spatial distribution of emissions on a grid with a resolution of 1 km x 1 km. The spatial mapping is an important input for the atmospheric dispersion modelling carried out by the Department.
The Department also contributes to advisory projects for national authorities and the European Commission, where advise has been provided, e.g. in relation to the review of Member States base years under the Effort Sharing Decision and in connection with improving and updating the European EMEP/EEA Guidebook.
