Motor Vehicles: Exhaust Emissions

Question: To ask Her Majesty’s Government what assessment they have made of emission tests undertaken by car manufacturers in the UK.

Answer: As part of the exhaust emissions approval process vehicle manufacturers are obliged to undertake in-use emissions testing. They are required to submit a report of their results at regular intervals or when requested to do so by the approval authority. In accordance with EU regulation 715/2007, the authority will review the information and accept or reject the report. The UK type approval authority is the Vehicle Certification Agency (VCA) and they ensure manufacturers follow this process where they are the issuing approval authority.
