TfL Ref 0003-2122 Thank you for your request received by Transport for London (TfL) on 1 April 2021 asking for information about our licensed taxi vehicle fleet. Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. You asked: Of the current licensed taxi fleet, please provide me a breakdown of the Euro/Zec class. To clarify, I wish to know how many vehicles are ZEC, Euro6, Euro5 etc. I can confirm that we hold this information which can be found in the table below. The data is correct as of 1 March 2021 when we last compiled this information. Taxi fleet emission standards as of 1 March 2021 Euro 2 5 Euro 3 608 Euro 4 2,982 Euro 5 3,518 Euro 6/ZEC 6,547 Total 13,660 Please note, the table doesn’t account for vehicles that have been converted to LPG as we have determined the Euro standard based on the DVLA registration date. 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. 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 as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.
