FOI - ULEZ and climate change [May 2023]

Key information

Request reference number: MGLA020523-6098

Date of response:

Summary of request

Your request

Given the extent to which the Ultra Low Emission Zone (ULEZ) resulted in replacing older vehicles (increased car manufacturing carbon that is responsible for around 9 per cent of global greenhouse gases), I would like to know what technical advice he received to justify his assertion that the ULEZ will help fight climate change.

I assume his not knowing that climate change and air pollution are caused by different 
emission gases was his own error rather than coming from technical advice he received. If that is not the case, provide details of any briefing you gave him.

If you have such an analysis of the ULEZ climate impact, please share it.

Our response

I understand that you have sent the same request to Transport for London (TfL) and that TfL has responded.

As the Mayor's transport authority, TfL is responsible for the policy development, implementation and ongoing operation of road user charging schemes such as the ULEZ.

TfL prepared the consultation documents for the scheme, including working with Imperial College London to model the expected impacts.

If you have any further questions relating to this matter, please contact us, quoting 
reference MGLA020523-6098.
