Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to the Answer of 24 May 2023 to Question 185865 on Diesel Vehicles, how many diesel cars were registered for the first time in each borough in Greater London in (a) 2021, (b) 2022 and (c) each month in 2023.

The number of diesel cars registered for the first time to keepers in each borough in Greater London in (a) 2021, (b) 2022 and (c) each month in 2023, for which data are available, is provided in the Excel file attached.

Note that the keeper of the vehicle is responsible for registering and taxing the vehicle only. The keeper of the vehicle is not necessarily the owner or the driver, e.g. fleet vehicles owned by companies. Most (61% in 2022) new registrations of diesel cars are to company keepers.
