While air pollution legislation has undoubtedly resulted in an overall improvement of the air quality over the years, there are still problems, which are increasingly localised in specific regions and cities. A key issue is thus to determine at which scale to act in order to abate these remaining air pollution problems most effectively. In this Atlas, both the spatial (e.g. urban, country) and sectoral (transport, residential, agriculture…) contributions are quantified for 150 urban areas in Europe. The following conclusions are formulated: (1) for many cities, local actions at the city scale are an effective means of improving PM2.5 air quality in that city; (2) target sectors and scales to abate air pollution are city specific; (3) for many cities, sectoral measures addressing agriculture at country - or EU - scale have a clear benefit on urban air quality and (4) because of methodological choices and assumptions, the responsibility of a city in generating its air pollution is often underestimated. }, title = {Urban PM2.5 Atlas}, type = {Scientific analysis or review, Policy assessment}, url = {}, doi = {10.2760/356670 (online),10.2760/07645 (print)}
