Question to the Department for Transport:

To ask the Secretary of State for Transport, what discussions (a) he and (b) HS2 Ltd has had with HS2 Ltd's contractors on their awareness of HS2 Ltd’s environmental obligations on site air quality and pollution.

HS2 environmental requirements, including with respect to air quality, are embedded into HS2 contractors through their contractual requirements and the project’s Environmental Minimum Requirements. Integrated project teams for delivering Phase One of the railway ensure close working between client and contractor. HS2 contractors are required to be highly aware of, and compliant with, their air quality requirements and have in many cases bettered the project’s rigorous standards through their own environmental leadership.
