Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment she has made of the potential impact of Ultra Low Emission Zone penalty charge notices on levels of emissions.

Transport in London is devolved to the Mayor of London and Transport for London. This includes decisions on air quality measures and the operation and enforcement of the Ultra Low Emission Zone. The Department has therefore made no assessment of the potential impact of Ultra Low Emission Zone penalty charge notices on levels of emissions.
