Air pollution affects our health, environment and economy. To improve air quality, UNECE Member States have been successfully working to reduce air pollution since 1979 under the Geneva Convention on Air Pollution. To help countries do this, the UNECE has developed two e-learning courses with the possibility of receiving a certificate of completion. The courses on the Geneva Convention on Long-range Transboundary Air Pollution and its Protocols (four modules) and on developing emission inventories (three modules) are available in English and Russian.
