UNECE Convention on Long-range Transboundary Air Pollution

International Cooperative Programme on Modelling and Mapping of Critical Loads and Levels and Air Pollution Effects, Risks and Trends

The International Cooperative Programme (ICP) on Modelling and Mapping of Critical Loads & Levels and Air Pollution Effects, Risks and Trends works under the Convention on Long-range Transboundary Air Pollution of the United Nations Economic Commission for Europe (UNECE).

Chairman: Mr. Till Spranger (Germany),
Head of Coordination Centre for Effects (CCE): Mr. Jean-Paul Hettelingh (The Netherlands)

The objectives of the ICP Modelling and Mapping are to

(a) determine receptor specific critical loads for indirect effects of the (long-term) deposition of various air pollutants, and critical levels for direct effects of gaseous air pollutants;

(b) map pollutant depositions and concentrations which exceed critical thresholds; and

The mandate of the Coordination Centre for Effects (CCE) in the Netherlands Environmental Assessment Agency (MNP) includes the development of modelling and mapping methodologies for the assessment of critical loads and exceedances on a European scale.

At present 25 parties participate in the programme activities and contribute national data to produce European critical load maps. Results are published in bi-annual CCE Status Reports and scientific journals. The maps are used for integrated assessment modelling by the Task Force on Integrated Assessment Modelling (TFIAM). A recently revised Mapping Manual produced in collaboration with other ICPs describes methods to be used by National Focal Centers (NFC).
