Our Ref: FOI-0072-2324
Thank you for your request received on 8 April 2023 asking for information about the Ultra Low Emission Zone (ULEZ) charge.
Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm that we do hold the information you require.
The amount for the ULEZ charge was decided upon following evidence-based analysis for the Central London ULEZ in 2015 and following consultation for the inner-London expansion in 2017. For the London-wide ULEZ the charge level has been retained at previous levels already implemented following its success for the existing ULEZ.
The Report to the Mayor for the Central London ULEZ published in March 2015 sets out the rationale for the charge level. This stated that the charge level is, “based on the contribution to emissions of the vehicle, the propensity to travel in the zone and the likely response of the vehicle owner.” The supplementary information published for the inner London ULEZ consultation included analysis of the impact of the charge level to determine the extent to which different groups respond to different charge levels.
“The behavioural response to a range of charges for car drivers was modelled using stated preference survey data. At the lower range of charges there was a significantly lower range of expected compliance with the standards as a larger proportion of drivers would opt to stay and pay the charge.”
The Report to the Mayor for the London-wide ULEZ states, “The charge level of £12.50 has proved successful for both the central and the inner London ULEZ. It provides an effective incentive for frequent drivers of noncompliant vehicles to change their vehicles or mode of transport while still allowing infrequent journeys to be affordable.”
If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.
Please see the attached information sheet for details of your right to appeal.
Yours sincerely
Gemma Jacob Senior FOI Case Officer FOI Case Management Team General Counsel Transport for London
