Motor Vehicles: Exhaust Emissions
The question
To ask the Secretary of State for Transport, what assessment her Department has made of the contribution of illegally high vehicle emissions arising from the use of defeat devices to overall UK nitrogen oxide and greenhouse gas emissions levels.
Answered by Simon Lightwood
Defeat devices are illegal, misleading for drivers and can have negative health impacts on the public.
The Department for Transport has not conducted a specific assessment of the contribution of illegally high vehicle emissions arising from the use of defeat devices to overall UK Nitrogen Oxide and greenhouse gas emissions levels.
The Department for Transport, through the Driver and Vehicle Standards Agency, is leading investigations into suspected non-compliant diesel vehicles under assimilated Regulation (EU) 2018/858. Where non-compliance is identified, manufacturers are required to take corrective action.
