    Cleaner air in European cities as nitrogen dioxide levels drop with lockdowns

    Lockdowns in many European countries have curbed road transport - the largest source of nitrogen oxides - and slowed output at gas-emitting factories.

    Air pollution has decreased in urban areas across Europe during lockdowns to combat the corona-virus, new satellite images showed on Monday, but campaigners warned city-dwellers were still more vulnerable to the epidemic. Cities including Brussels, Paris, Madrid, Milan and Frankfurt showed a reduction in average levels of noxious nitrogen dioxide over Mar 5-25, compared with the same period last year, according to the Sentinel-5 satellite images.
