Excess emissions from diesel cars cause about 5,000 premature deaths annually across Europe, a new study shows.
Since the late 1990s the share of diesel cars in the EU has risen to around 50% in the fleet, with important variations between countries. There are now more than 100 million diesel cars running in Europe, twice as many as in the rest of the world together. Their NOxemissions are however 4 to 7 times higher on the road than in official certification tests. Modern engine controls have been optimized by manufacturers for the specific laboratory testing but underperform in real-driving. In this new study, researchers at IIASA and the Norwegian Meteorological Institute have calculated the premature deaths from these excess NOx emissions for the population in all European countries.
