Methods and 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 natural areas, including Natura 2000 sites. The CCE collaborates with National Focal Centres and many scientific institutions. Results are successfully used in European air pollution agreements since 1994.

CCE Environmental Impact Assessment (CCE-EIA) methods include the computation of maximum allowable levels of air pollution for the protection of biodiversity. These protection levels 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. Please check FAQs and methodological elements under: |
