Air quality: Pollution sources and impacts, EU legislation and international agreements

10-07-2018

Outdoor air pollution is caused by the emission of harmful substances from natural sources and human activities. It has a number of adverse effects on human health and the environment, and subsequently on society and the economy. Air pollution can be transported or formed over long distances and can affect large areas. Effective air quality policies require action and cooperation beyond the local and national levels, on a European and global scale. This publication presents key air pollutants, lists natural sources of air pollution, and details emissions from human activities by sector. It describes adverse effects on human health, the environment and the climate, as well as socio-economic impacts. In addition, it provides an overview of international agreements and European Union legislation setting air quality standards, lowering national emissions of pollutants, and reducing emissions of pollutants at specific sources. Furthermore, this publication briefly describes the state of implementation of key EU legislation related to air quality. Finally, it reflects the position of the European Parliament and stakeholders on the policy area.
