In September 2015, the German Volkswagen Group, the world’s largest car producer, admitted to having installed “defeat devices” in 11 million diesel cars sold worldwide between 2008 and 2015. The devices were designed to detect and adapt to laboratory tests, making the cars appear to comply with environmental standards when, in fact, they emitted pollutants called nitric oxides, or NOx, at levels that were on average four times the applicable European test-stand limit.

While Volkswagen has issued recalls of affected vehicles in both the U.S. and Europe, scientists at MIT and elsewhere have found the excess emissions has already had an impact on public health. The team previously estimated that the excess emissions generated by 482,000 affected vehicles sold in the U.S. will cause approximately 60 premature deaths across the U.S.
Now the researchers have looked closer to Volkswagen’s home base, examining the health impact from the 2.6 million affected cars sold in Germany under Volkswagen Group’s brands VW, Audi, Skoda, and Seat. In a paper published today in Environmental Research Letters, the team reports that the manufacturer’s emissions in excess of the test-stand limit value have had a significant effect on public health not just in Germany but across Europe.
