Convention on long-range trans boundary air pollution . .


The Convention on Long-Range Transboundary Air Pollution (CLRTAP) is an international treaty designed to address the issue of air pollution that travels across national boundaries. It was adopted in 1979 and entered into force in 1983 under the auspices of the United Nations Economic Commission for Europe (UNECE).The main objective of the CLRTAP is to reduce and prevent air pollution, particularly those pollutants that have adverse effects on human health and the environment. The convention provides a framework for countries to cooperate and develop strategies and measures to tackle transboundary air pollution collectively.The CLRTAP is a legally binding agreement that has been ratified by over 50 countries in Europe and North America. It establishes a system for monitoring and assessing air pollution levels, as well as setting emission reduction targets and developing control measures.The convention has been successful in addressing several major air pollutants, such as sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), and persistent organic pollutants (POPs). It has led to the development of protocols and amendments targeting specific pollutants and emission sources, including the 1994 Sulphur Protocol, the 1998 Nitrogen Oxides Protocol, and the 1999 Gothenburg Protocol, among others.Through the CLRTAP, member countries have implemented various measures, including the use of cleaner technologies, emission standards for vehicles and industrial sources, and the promotion of renewable energy sources. The convention also encourages scientific research, data exchange, and public awareness about the impacts of air pollution.Overall, the CLRTAP has played a significant role in improving air quality and reducing the adverse effects of transboundary air pollution in Europe and North America. It continues to provide a platform for international cooperation and concerted efforts to address air pollution and its cross-border impacts.
