Despite the importance of airspace modernisation, and the relative speed with which it could be introduced compared with other decarbonisation measures, the Airspace Change Organising Group is not a member of the Jet Zero Council. The Committee recommends that the Airspace Change Organising Group should be elevated to full membership of the Jet Zero Council. That would signal the serious intent of the Government to implement the required changes to airspace modernisation as quickly as possible.
