White cloud streaks high up in the sky are one of the ways you can tell a plane has been overhead. And although they can form striking patterns in the sky, these contrails and the cirrus clouds they induce, impact climate change, possibly greater than the effect from CO2 emissions.

In April I attended the annual IATA Ops Conference in Ottowa, where we were able to share a vision for transatlantic flights in 2025, jointly developed by us at NATS and the Canadian air traffic service, NAV CANADA. The video we produced is aimed at an aviation audience but hopefully it gives any viewer an idea of the huge amount of work that we’re doing with NAV CANADA to transform transatlantic operations to make it safer, cleaner and far more efficient.
