Air pollution is already one of the biggest public health concerns in Europe: in 2016, roughly 412,000 people died prematurely due to long-term exposure to ambient PM2.5, 71,000 due to NO2 and more than 15,000 premature mortalities occurred due to near- surface ozone . The impacts of air pollution are determined by air-quality policies, changes to temperature, humidity and precipitation . Climate change could increase air pollution health effects, with the size of the effect differing across European regions and pollutants  . Increases in temperature and changes in precipitation will impact future air quality due to increased risk of wildfires and related air pollution episodes. Data on the health impacts of wildfires in Europe is currently limited , but examples, such as the 2017 fires, suggest that more than 100 people died prematurely in Portugal alone as a result of poor air quality .
