Methods & Models

The CCE is responsible for the development of modelling methodologies and databases for the integrated assessment of effects of air pollution (under climate change) on biodiversity in European (semi-)natural areas. Results are successfully used in European air pollution agreements

Critical loads

Since 1994 the CCE Environmental Impact Assessment (CCE-EIA) methods include the computation of maximum allowable thresholds of air pollution for the protection of biodiversity. These thresholds are called "critical loads". Adverse effects occur when critical loads are exceeded by atmospheric deposition of compounds such as sulpur, nitrogen and heavy metals. Protection levels can change as function of climate change. The focus is currently on effects of excessive nitrogen deposition.
