Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 29 June 2026 to Question 11818 on Airspace, whether she has made an estimate of the cumulative additional CO₂e emissions resulting from delays to the implementation of Free Route Airspace against the original planned implementation timetable.

The transition to Free Route Airspace has been delivered broadly in line with anticipated timescales, with deployments completed in Northern Scotland and Northern Ireland (2021), Southwest England (2023) and Southern Scotland and Northeast England (2026).

Future deployments are dependent on other airspace modernisation and technology programmes. As the benefits of future phases remain subject to the completion of this interdependent work, no estimate has been made of any cumulative additional CO₂e emissions resulting from changes to the implementation timetable.
