Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 30 April 2019 to Question 249314 on Railways, what assessment he has made of the effect of (a) a Western Rail Link to Heathrow Airport and (b) a Southern Rail Link to Heathrow Airport on the level of emissions of (i) greenhouse gases and (ii) other atmospheric pollutants in relation to (A) the existing configuration and (B) the addition of the North West Runway at London Heathrow Airport.

When developing the Airports National Policy Statement (ANPS), the Government considered the environmental impacts of airport expansion, including surface access, in its assessment. The ANPS is clear that a new Northwest Runway will not receive Development Consent unless it can demonstrate compliance with air quality and climate change obligations.

Specific assessment of air quality and climate change impacts associated with the proposed Western and Southern Rail Links will form part of the required environmental assessments accompanying any development consent application. Both schemes are intended to support travel mode shift from road to rail, therefore supporting air quality and climate change targets.
