You asked

Therefore under the FOI Act, I would like to know how many petrol cars are on you database that have higher than 0.08gms/Km NOx level and are still compliant.

We answered

TfL Ref: 1783-2324

Thank you for your request received by Transport for London (TfL) on 28 August 2023 asking for information about the number of petrol cars on our database that have higher than 0.08gms/Km NOx level and are still compliant.

Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy.  You asked: how many petrol cars are on you database that have higher than 0.08gms/Km NOx level and are still compliant.

We do not hold the information you have requested - our compliance database does not contain vehicle emissions data as we do not need to retain this specific information in order to operate our schemes once compliance has been determined, supported by DVLA data.

As mentioned previously, you will receive a separate response to your other general queries.

Please see the attached information sheet for details of your right to appeal.

Yours sincerely


Sara Thomas

General Counsel
