OF AVIATION'S CLIMATE IMPACT

The UK Government has teamed up with Google on a new initiative to shrink aviation's climate footprint by tackling contrails — the vapour trails planes leave behind that are estimated to drive a significant share of the industry's warming effect. A £5m, 30-day trial will use Met Office forecasting and Google's AI to reroute flights over the North Atlantic away from the conditions that cause the most persistent trails.

Why Contrails Matter

Research from Resources for the Future, cited in the announcement, found contrails are responsible for between 1% and 2% of total global warming and as much as 57% of aviation's entire climate impact. That's because the trails can seed the formation of cirrus-like clouds that trap heat in the atmosphere.

The new partnership follows £219m already committed by the UK's Department for Transport in June toward clean fuel production for aviation, a move that came after Court of Appeal rulings cleared the way for expansion at Gatwick and Luton airports.

How the AI Trial Will Work

The government will combine Met Office weather forecasts with Google's AI models to identify where vapour trails are likely to form along certain North Atlantic flight routes, then suggest small tweaks to flight paths to avoid those conditions. Testing is set to run during the winters of 2026-27 and 2027-28, operating within normal air traffic control procedures.

"By testing small tweaks to flight paths over the Atlantic, we can cut the vapour trails left behind by planes."

— Keir Mather, UK Government Minister for Aviation, Maritime and Freight

A Broader Push Toward Zero-Emission Flight

Alongside the contrail trial, the government is putting £43m toward clean aviation technologies, including electric and hydrogen-powered aircraft and flying taxis. Vertical Aerospace, which builds zero-emission electric vertical take-off and landing aircraft, is among the likely recipients, with up to £3.2m earmarked to demonstrate how its next-generation aircraft can fit into commercial airport operations.

Officials framed the combined effort as part of the UK's Modern Industrial Strategy and its funding through the ATI Programme, aimed at keeping the country's aerospace sector competitive on the path to net zero.
