The LRTAP Convention entered into force 1983. The Convention which has 51 Parties was the first international legally binding instrument to deal with air pollution on regional bases. The aim of the Convention is that Parties shall endeavor to limit and, as far as possible, gradually reduce and prevent air pollution including long-range transboundary air pollution by developing policies and strategies to combat the discharge of air pollutants through exchanges of information, consultation, research and monitoring (see status of ratification).


The WGSR (Working group on Strategies and Review) is the principal negotiating body for the Convention.


The EMEP (European Monitoring and Evaluation Programme) is carried out in collaboration with a broad network of scientist and national experts. The EMEP provides scientific support to the LRTAP Convention on:

  • Atmospheric monitoring and modeling
  • Emission inventories and emission projections
  • Integrated assessment modeling

The TFEIP (Task Force on Emission Inventories and Projections) supports Parties in reporting of air emissions and projections to the Convention by providing technical forum and expert network to identify problems and establish methodologies for the emission estimation.


The Arctic Council is the leading intergovernmental forum promoting cooperation, coordination and interaction among the Arctic States, Arctic indigenous communities and other Arctic inhabitants on common Arctic issues, in particular on issues of sustainable development and environmental protection in the Arctic. 



The convention has been extended by eight protocols (1985 - 1999) that identify specific measures to be taken by Parties to cut their emissions of air pollutants.
