Thank you for your request received on 20 December 2018 asking for information about taxi emissions
Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy. I can confirm we do hold the information you require.
The proportion of emissions of oxides of nitrogen (NOx) from taxis in London is derived from the London Atmospheric Emission Inventory (LAEI). The LAEI is a regularly updated database of pollutant emissions and sources including geographically referenced data and maps. It is publicly available on the London Datastore at https://data.london.gov.uk/.
The relative contribution to total road transport emissions of each vehicle type is estimated using information on the composition of the vehicle fleet, the annual distances covered, emissions factors for that class of vehicle and information on the road links on the London network. The contribution to total NOx emissions from taxis in Central London by 2020 is estimated at around 30 per cent, making them the largest single contributor to NOx concentrations in that area.
If this is not the information you are looking for, or if you are unable to access it for some reason, please feel free to contact me.
Please see the attached information sheet for details of your right to appeal.
