Planes Rerouted to Fight Climate Change in Airspace Trial
18 Aug
Summary
- Flights will be rerouted to avoid forming climate-warming contrails.
- AI forecasts predict atmospheric conditions for contrail avoidance.
- A two-year trial in the North Atlantic airspace aims to reduce warming.
Planes traversing the North Atlantic will soon be rerouted to mitigate the climate impact of condensation trails. This novel trial, commencing later this year, will see air traffic controllers in the Shanwick airspace utilize Google's AI-generated forecasts to predict and avoid contrail formation.
The Operation Blue Skies project will conduct four-month winter trials over two seasons: 2026-2027 and 2027-2028. Approximately 10,000 flights are expected annually, with hundreds requiring altitude adjustments of up to 2000 feet to circumvent conditions conducive to persistent contrails.
This airspace-scale initiative, affecting all aircraft, aims to cut contrail warming by 50 to 60 percent. While rerouted flights may incur additional fuel burn, the climate benefits are projected to outweigh this minor increase, addressing a significant portion of aviation's overall climate contribution.
