Automakers on Trial for Alleged Emissions Cheating, Thousands of Lives at Stake
15 Nov
Summary
- Carmakers accused of installing "defeat devices" to cheat emissions tests
- Lawsuit claims 500,000 diesel cars in UK emitting higher pollution levels
- Nitrogen dioxide pollution linked to over 124,000 premature deaths in UK and Europe

In a landmark trial that began on October 13, 2025, several major automakers are facing allegations of installing "prohibited defeat devices" to cheat emissions tests. The lawsuit claims that while these vehicles passed emissions tests, they were actually emitting higher levels of nitrogen dioxide pollution when in regular operation.
The trial focuses on Mercedes, Ford, Nissan, and Peugeot/Citroën, but other manufacturers like Jaguar Land Rover, Volkswagen, and Toyota are also involved. Lawyers estimate that around 500,000 diesel cars with this technology are currently on UK roads.
Nitrogen dioxide pollution has been linked to over 124,000 premature deaths in the UK and Europe between 2009 and 2024. Exposure to this gas can cause serious health issues, including inflammation, reduced lung function, and increased risk of heart problems and cancer.
The case was brought to the high courts, and a judgment is expected by the summer of 2026. Holding these corporations accountable for their contributions to pollution is of utmost importance, as this trial will have far-reaching implications for the automotive industry and public health.
