Diesel cars emit more air pollution on hot days, study says
Emissions rose 20-30% in Paris when temperatures topped 30C, raising urgent questions as the climate gets hotter
Emissions from diesel cars – even newer and supposedly cleaner models – increase on hot days, a new study has found, raising questions over how cities suffering from air pollution can deal with urban heat islands and the climate crisis.
Research in Paris by The Real Urban Emissions (True) initiative found that diesel car emissions of nitrogen oxides (NOx) rose by 20% to 30% when temperatures topped 30C – a common event this summer.
Emissions from a range of vehicles were found to be many times higher than those declared by manufacturers in laboratory tests, confirming earlier findings following the 2015 Dieselgate scandal, in which Volkswagen cars were found to emit 40 times more NOx on the road than during laboratory tests. read more »
