Data shows only 127 of 323 cities had acceptable PM 2.5 levels despite drop in emissions during lockdowns
More than half of European cities are still plagued by dirty air, new data shows, despite a reduction in traffic emissions and other pollutants during last year’s lockdowns.
Cities in eastern Europe, where coal is still a major source of energy, fared worst of all, with Nowy Sącz in Poland having the most polluted air, followed by Cremona in Italy where industry and geography tend to concentrate air pollution, and Slavonski Brod in Croatia.
