New report available: Critical loads for eutrophication and acidification for European terrestrial ecosystems

The project aimed to improve the European background database used by the Coordination Centre for Effects (CCE) to calculate Critical Loads (CLs) for eutrophication and acidification for (semi-) natural European terrestrial ecosystems. The database is used when member countries do not provide their own CL data to the CCE. In this case, the missing country data are replaced by the results of the background database when the CCE produces European CL maps. This report describes the (a) underlying datasets; (b) derivation of the input data for the CL model; (c) R packages and scripts developed; and (c) verification of the results. These results feed into international and national policy advice, e.g., they are an important input to the Gothenburg Protocol Review currently underway in the year 2021.

We are pleased to announce that the report on the background database project has been published and can be downloaded here.


Expert Workshop on Empirical Critical Loads for Nitrogen

Dear ICP M&M NFCs, colleagues and friends, 

Dear experts and authors of the draft updated report on empirical critical loads for nutrient nitrogen,

The Coordination Centre for Effects (CCE) and the Swiss Federal Office for the Environment (FOEN) are pleased to invite you to the Expert Workshop on Empirical Critical Loads for Nitrogen, held from 26th to 28th October 2021 in Bern, Switzerland. This meeting is held under the UN/ECE Convention on Long-Range Transboundary Air Pollution under the auspices of the International Cooperative Programme on Modelling and Mapping of Critical Levels and Loads and Air Pollution Effects, Risks and Trends (ICP M&M).

The workshop aims at reporting on the progress of each ecosystem specific expert group in plenary (day 1), at discussing within the expert groups (day 2) and at reporting back for final conclusions (day 3). For more detailed information, please refer to the draft agenda. Here you will find the invitation letter to the workshop and all the needed information to join.

We are looking forward to meeting you in Bern.

Best regards,

Reto Meier, Alice James Casas, Christin Loran


ICP Modelling & Mapping Meeting 2021

The documents and presentations from the 37th TF, 28th CCE & 2nd CDM Meeting of the ICP M&M are available here



The CCE aims at establishing a more dynamic communication within the WGE, and especially with its NFCs. Togehter with the TF Modelling & Mapping and the Centre for Dynamic Modelling (CDM) we plan to publish a newsletter at least twice a year. Please, feel free to submit information relevant for the whole group so we can include it into our next newsletter.
