Your January 2022 report, London Net Zero 2030: An Updated Pathway, contains a scenario that would reduce car vehicle kilometres by 27 per cent by 2030 to reduce transport emissions. The pathways tool that accompanies the report does not provide any breakdown of the necessary reduction in car vehicle kilometres by borough, and instead represents these changes by broad groups of traffic and type of fuel. Could you provide a table that gives the reduction in vehicle kilometres, by type of vehicle, by year from 2020 to 2030 that each borough in London needs to deliver?

This data should have been available in the tool but due to a technical error, the borough transport km data was not being displayed in the dashboard. This has now been corrected in the updated version of the tool on the datastore. By selecting the chosen borough on the dashboard, along with “transport” and “road transport vehicle kilometres” from the relevant drop down menus, vehicle km data is displayed on the dashboard for five-year increments, with yearly data made available at the bottom of the “Main graph Results” worksheet. This data is also provided in a single table here.

It should be noted that in the tool the borough vehicle kms are scaled from the overall vkm for London, according to the distribution of traffic and emissions in the London Air Emissions Inventory (LAEI). As such, the same relative reduction in vkm levels is assumed for all boroughs. In practice this will not be the case since each borough has different potential for shifting away from vehicles.
