Make polluters pay for poisoning our children

Ensure Dieselgate car manufacturers clean up illegally polluting cars to protect our children’s health

Why is this important?

10 years ago it was revealed that many diesel cars were being fitted with illegal technology that means they emit levels of toxic gases (NOx) exceeding testing and legal limits. These emissions poison everyone, especially our children, and millions of these cars remain on our roads today.

NOx inflames lungs, exacerbates asthma and globally causes 20% of all childhood asthma cases.

Governments in Germany and the USA have taken action and made the car manufacturers pay billions to clean up the air they polluted, and have sent people responsible to prison. But in the UK, car manufacturers have never been held to account. 

The excess NOx emissions from diesel vehicles have been responsible for a staggering 30,000 cases of asthma in children and a £96 billion cost to the economy between 2009 and 2024 in the UK. Most of these cars are still being driven on our roads, polluting neighbourhoods and lungs, and it is time to take action.
