FOI - Retrofit technology for London's buses [Jul 2023]

Key information

Request reference number: MGLA310723-3133

Date of response:

Summary of request

Your request

From a previous Freedom of Information request I see all London buses are ULEZ compliant. You stated that a special device has been retrofitted that removes whatever gases needed to make them compliant.

Please confirm:

  • The name of the device.
  • The name of the company supplying the device.
  • The name of the company fitting the device.
  • The name of the company checking emissions to guarantee compliance.

Our response

The GLA does not hold this information.

Transport for London (TfL) publishes fleet vehicle operational data online.

This data shows which vehicles were converted to meet the Euro VI emission standards.

The London bus operators selected retrofit technology from approved suppliers depending on their vehicle type.

TfL is the Mayor's transport authority and is responsible for implementing the Mayor's Transport Strategy, including delivery of policies to reduce emissions from its bus fleet. You may wish to send a further request to TfL at [email protected]

If you have any further questions relating to this matter, please contact us, quoting reference MGLA310723-3133.
