Answer from Hansard

The Parliamentary Under-Secretary of State for Energy Security and Net Zero (Katie White)

I share my hon. Friend’s concern regarding those reports. This Government are focused on making transport greener, including by cutting air pollution to improve health and the environment. We also need to ensure that people are abiding by the rules. The responsible body, the Driver and Vehicle Standards Agency, is pursuing the potential diesel emissions non-compliance using its procedures and the tools available. Officials at the DFT have assured me that the findings from these investigations will be published in a timely and appropriate manner; as an impatient politician, I can assure her that I will continue to press for a prompt and thorough interpretation of “timely”.
