I am writing to request what factual information, from which source/s and how and when it was obtained, was used to support the following statement made by TfL:
New Transport for London (TfL) data shows that nine in 10 cars seen driving in outer London on an average day meet the Ultra Low Emission Zone standards. The figures show the effectiveness of the scheme, which will expand London-wide from 29 August this year, in encouraging people to switch from older, more polluting vehicles. It is expected that when the standards cover the larger area, the proportion will be even higher. In November 2021, TfL estimated car compliance at 85 per cent, up from around 75 per cent estimated from earlier analysis of cars seen in June 2020.
