Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what discussions he has held with the Secretary of State for Environment, Food and Rural Affairs and the Secretary of State for Transport regarding cross-government action to address illegal levels of nitrogen oxide emissions from vehicles fitted with defeat devices.

The Secretary of State for Energy Security and Net Zero (DESNZ) engages regularly with the Secretary of State for Environment, Food and Rural Affairs (Defra) and the Secretary of State for Transport (DfT) on climate change mitigation. Transport policy, including transport emissions, is led by DfT. The Driver and Vehicle Standards Agency 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.
