This report describes activities by the Coordination Centre for Effects (CCE) since the CCE was transferred from the Dutch National Institute for Public Health (RIVM) to the German Environment Agency (UBA) in 2018. The CCE is the programme centre for the International Cooperative Programme on Modelling and Mapping (ICP M&M) under the Working Group on Effects of the Convention of Long-range Transboundary Air Pollution (CLRTAP). The mandate of the CCE is to develop and update methodologies for assessing critical loads (CL), to compile data on CL and to generate maps of CL and their exceedances.
