Germany Scores Another Own Goal With Diesel

German carmakers have promised to swiftly investigate experiments that exposed people and monkeys to diesel fumes, disclosures that threaten to open a new phase in an emissions controversy that’s dogged the industry since 2015.

One of the experiments studied the health effects of emissions in the workplace. It was carried out at the University of Aachen in Germany and backed by a little-known group funded by Volkswagen AG, Daimler AG and BMW AG. Reports of the tests followed a New York Times account of similar experiments on monkeys in the U.S., triggering political recriminations and prompting automakers to distance themselves from the work.
