Google Launches Operation Blue Skies to Cut Contrails With AI
The trial moves contrail avoidance from individual airline actions to coordinated airspace-wide routing, targeting the region where 5% of warming-affecting contrails occur.

Google, the UK government, and the aviation industry launched Operation Blue Skies, a 30-month trial to reduce warming contrails in the Shanwick Oceanic Control Area over the North Atlantic. AI models will reroute some of about 10,000 flights to avoid contrail formation, with partners handling trials, evaluation, and verification.
Contrails form when water vapor condenses on soot in jet exhaust, and they account for about one-third of aviation's climate impact. Google's Project Contrails showed that AI predictions can help flight crews and controllers avoid contrail-prone airspace. Operation Blue Skies extends that work across the entire Shanwick Oceanic Control Area, the eastern half of North Atlantic airspace.
Over 30 months, roughly 10,000 flights will pass through the area, and some will be rerouted to prevent contrail formation. Google develops the AI models and uses satellite imagery to verify effectiveness. NATS runs airspace trials and controller training, Contrails.org designs test parameters, and Imperial College London, Cambridge, and the UK Met Office handle evaluation and prediction systems.
