Europe's climate goals must not be compromised by supersonic aircraft

In this letter, NGOs Aviation Environment Federation, Carbon Market Watch and Transport & Environment tell European ministers for climate and transport that the excessive environmental and climate implications of supersonic flight are beyond doubt. They call on the ministers to make clear that Europe’s commitment to meeting the goals of the Paris Agreement will require the environmental performance of all new supersonic aircraft to at least meet existing and future environmental standards applicable to subsonic aircraft and so avoid any deterioration in aircraft environmental impacts. Given aviation’s already considerable environmental impact, it is imperative that Europe’s regulators act firmly and without delay to protect European citizens.
