On your website, https://tfl.gov.uk/modes/driving/ultra-low-emission-zone/ulez-expansion you state Four out of five cars already meet the ULEZ emissions standards, but we need owners of older polluting cars, motorcycles, lighter vans and minibuses to take action. As this is referring to the extension zone ... please provide the information to prove that 4 out 5 cars registered in the ULEZ extension zone already meet the new requirements I suspect that you are including cars already registered within the existing ULEZ zone. Thus the number of car in the extension zone that meet requirements are much lower and you claim is false and misleading.

TfL Ref: FOI-2024-2021

Thank you for your request received by Transport for London (TfL) on 7^th January 2021 asking for information about the ULEZ extension.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. 

Specifically you asked:

“On your website, https://tfl.gov.uk/modes/driving/ultra-low-emission-zone/ulez-expansion you state

Four out of five cars already meet the ULEZ emissions standards, but we need owners of older polluting cars, motorcycles, lighter vans and minibuses to take action.

As this is referring to the extension zone ... please provide the information to prove that 4 out 5 cars registered in the ULEZ extension zone already meet the new requirements

I suspect that you are including cars already registered within the existing ULEZ zone. Thus the number of car in the extension zone that meet requirements are much lower and you claim is false and misleading.”

The ‘four out of five’ figure represents the proportion of vehicles that meet the ULEZ required emissions standards that are detected by our Automatic Number Plate Recognition Cameras (ANPR) driving in the expanded ULEZ on an average day - based on an estimated 540,000 cars seen in the expanded ULEZ on an average day. The four out of five figure does not relate to the number of ULEZ compliant vehicles registered to addresses in the expanded ULEZ.

If this is not the information you are looking for please do not hesitate to contact me.

If you are considering submitting a further FOI request please think carefully about whether the request is essential at this current time, as answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. Where requests are made, please note that our response time may be impacted by the current situation.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely,

David Wells
