Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps his Department will take to measure the effect of pollution on Bullsmoor Lane as a result of the M25 junction development scheme.

Highways England’s assessment of the impact of the scheme concluded that changes in air quality as a result of the scheme would be negligible. Air quality monitoring on Bullsmoor Lane is already being carried out by the London Borough of Enfield, as the relevant local authority. Since construction on the scheme has started, they have not notified Highways England of any exceedances recorded for any monitoring stations within the locality of Bullsmoor Lane. As this monitoring is already in place, Highways England has no plans to implement further monitoring in the locality.
