TfL Ref: FOI-3441-1819

Thank you for your email received by Transport for London (TfL) on 17 March 2019, asking for information about the expanded ULEZ zone.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.  I can confirm we hold some of the information you require. You asked for:

1. Your estimate of how many vehicles will be affected which are resident within the zone.

    

2. Same for visiting vehicles.

    

    

   This data was provided as part of the consultation material on the expansion of ULEZ. We estimate that for the ULEZ expansion in 2021 there would be on average 100,000 cars and 35,000 vans that would be affected.

    

3. Details of consultations which have taken place prior to the decision. Reference to the web address please.

    

    

   Please see the consultation details available via the below website;

    

   https://consultations.tfl.gov.uk/environment/ultra-low-emission-zone/

    

   An initial consultation on proposals to change the ULEZ was undertaken by the GLA from 5 to 29 July 2016. Please see  https://data.london.gov.uk/dataset/clean-air-consultation-july-2016 

    

   This was followed up by another policy consultation on changes to the ULEZ from 10 October to 18 December 2016. Please see https://consultations.tfl.gov.uk/environment/air-quality-consultation-phase-2/

    

   The statutory consultation to introduce the ULEZ in central London took place between 4 April and 25 June 2017. Please see https://consultations.tfl.gov.uk/environment/air-quality-consultation-phase-3a/

    

   The statutory consultation to expand the ULEZ took place between 30 November 2017 and 28 February 2018. Please see https://consultations.tfl.gov.uk/environment/air-quality-consultation-phase-3b 

    

4. Estimate of how many (on average) cars which will be subject to the new rules have equal emissions to an existing London bus.

    

    

   Using emissions factors from COPERT 5 (the widely recognised European emissions factors programme) which is used for air quality modelling, the oxides of nitrogen (NOx) emissions estimated for a non-compliant (Euro 3) petrol car and a non-compliant (Euro 5) diesel car travelling at 20km/h are shown below. This is with a comparison to a Euro VI diesel double-deck bus, of the type used in central and inner London. Please note that an increasing number of TfL buses are actually battery electric vehicles with zero tailpipe emissions.

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

    

   Vehicle type

   NOx emissions at 20km/h

   non-compliant (Euro 3) petrol car

   0.11g/km

   non-compliant (Euro 5) diesel car

   0.79g/km

   Euro VI diesel double deck bus.

   0.48g/km

    

    

    

   It is also worth noting that the multi-occupancy usage of a bus means that emissions per passenger-kilometre are much lower than those of a car.

    

5. Was there any consultation with the Government Department which recommended car buyers to buy diesel vehicles.

    

    

   A full list of consultees is available within the consultation reports.

   Appendix B of the November 2017 consultation https://consultations.tfl.gov.uk/environment/air-quality-consultation-phase-3b/user_uploads/ulez-consultation-appendices-a-h.pdf

    

6. An estimate of the annual gross revenue which the scheme will produce, and the annual costs.

The forthcoming introduction of the ULEZ and its expansion to inner London in 2021 is not about making money, but about improving the health and wellbeing of thousands of Londoners. Any revenue generated from the ULEZ will be reinvested into improving the transport network and making London’s air cleaner.

ULEZ income is incorporated into the overall Transport for London Business Plan under ‘other operating income’. The table below shows the projected net operating income from the first phase of ULEZ in central London. The net operating income includes both charge and enforcement income and is net of operating costs and other expenses. These figures have been rounded to the nearest million.

The figures are complete for the ULEZ however, they are not split as requested as the ULEZ and the expansion is considered as one scheme.

ULEZ Net Operating Income (£m)	2019/20	2020/21
Gross Income	174	120
Operating Costs	(46)	(37)
Total Net Income	128	83

7. How will the scheme be enforced for subject vehicles parked at home when taken on to the streets.

The ULEZ will operate using Automatic Number Plate Recognition technology. As a vehicle enters, leaves or drives within the zone its registration is recorded along with a colour image of the vehicle. At the end of the next working day, when the payment period has expired, the list of vehicles observed in the zone is compared against those vehicles for which a charge has been paid, meet the standards, exempt from the charge or registered on an Auto Pay account. Where a match is found the image and record of the vehicle is deleted. If no match is found the details are retained for enforcement purposes.

No charge is payable for parked vehicles. However once they are driven within the zone they become subject to the charge.

If this is not the information you are looking for, or if you are unable to access it for some reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely
