Request ID: FOI-0551-2223 Date published: 22 June 2022
You asked
After having talked to someone on the phone from tfl I was told to send an email to this address and with the freedom of information ask if i could know the amount of different vehicles that enter the ULEZ zone everyday and also know how many comply with the ULEZ zone requirements and how many do not comply and have to pay a charge. I would also like to get the numbers on the difference between when the zone was implemented and now to compare the changes it has caused to pollution in london.
Finally I would also like to get the difference in numbers of people that ride on public transports before the ULEZ zone was implemented and now that the ULEZ zone has been implemented.
I would like to use this information for a project I have regarding the Extended Essay for the International Baccalaureate. I am researching how the ULEZ zone was successful or not in reducing the negative externalities of pollution in London.
Many thanks for your kind assistance.
