non ULEZ compliant buses

Request ID: FOI-0295-2324
Date published: 17 May 2023

You asked

Please can you tell me how many buses operating in the outer GLA area (so the area in which the expanded ULEZ is proposed) are compliant with the ULEZ standards? I know there are some electric buses, but I have seen several diesel buses with 59 number plates and want to be reassured that they are compliant.
