Diesel Vehicles: Exhaust Emissions

The question

To ask the Secretary of State for Transport, if she will take steps to ensure that diesel vehicle manufacturers responsible for illegal emissions practices contribute to environmental remediation or compensation schemes.

Answered by Simon Lightwood

The Government takes illegal emissions practices extremely seriously. The Driver and Vehicle Standards Agency’s Market Surveillance Unit (MSU) is investigating cases of possible non-compliant diesel emissions in cars and vans. The investigations aim to ensure any non-compliance found is fixed as soon as reasonably possible, working together with manufacturers to achieve real-world impacts on air quality.
