Although data from the Copenhagen-based European Environment Agency (EEA) reveals some encouraging signs, in large part the result of new technologies, air pollution remains the leading environmental cause of premature death in the region.
In its latest report, the EAA said 520,400 premature deaths in 41 European countries were caused by air pollutants generated by the burning of fossil fuels in 2014, compared with 550,000 in 2013.
Of these, four out of five deaths (428,000) were directly linked to fine particulate matter, which measure less than 2.5 microns and can enter a person's lungs and even the bloodstream.
Data collected at monitoring stations showed that 82 percent of the EU's urban population was exposed to these microscopic particulates, known as PM2.5, in 2015, down from 85 percent in 2013.
Other sources of air pollution linked to the premature deaths include nitrogen dioxide, emitted in the air, and ground-level ozone caused by motor vehicle emissions.
Within the 28 European Union members, fine particulates were responsible for more than three out of four premature deaths (399,000 out of 487,600) in 2014.
“The European Commission is committed to tackling this and help member states make sure that the quality of their citizens' air is of the highest standard,” said Karmenu Vella, the EU commissioner for the environment, maritime affairs and fisheries.
