Air pollution cause health problems and damage to historic buildings, monuments and ecosystems. In 1979, the Convention on Long-range Transboundary Air Pollution was signed to address this threat. Degradation to materials in Europe is today much lower, mainly due to reduction of sulphur pollution. Air pollution is still a problem but more complicated, where effects are the result of a multitude of harmful air pollutants and effective strategies for reduction need to go side by side with strategies for dealing with climate change.
The successful International agreements (Protocols) within the Convention on Long-range Transboundary Air Pollution have been based on a good scientific understanding of the release, transport and harmful effects of air pollution. The International Co-operative Programme on Effects on Materials including Historic and Cultural Monuments (ICP Materials) is one of several effect oriented International Co-operative Programmes reporting to the Working Group on Effects, which together with the European Monitoring and Evaluation Programme provides the science for the policy process.
