The European Environment Agency has recently published the 2017 edition of “Air Quality in Europe”. This report presents an updated overview and analysis of air quality in Europe from 2000 to 2015. Among other, it reviews the progress made towards meeting the air quality standards established in the two European Ambient Air Quality Directives, and towards the long‑term objectives of achieving levels of air pollution that do not lead to unacceptable harm to human health and the environment. According to this report, air pollution continues to have significant impacts on the health of the European population, particularly in urban areas with Europe’s most serious pollutants in terms of harm to human health being Particulate Matter (PM), nitrogen dioxide (NO₂) and ground-level ozone (O₃).
