Partners Launch Operation Blue Skies to Reduce Aviation Climate Impact

Google and the UK government have launched a 30-month trial, Operation Blue Skies, to test whether aircraft can avoid creating contrails by shifting altitude slightly. The project will run over Shanwick oceanic airspace and aims to reduce aviation’s climate impact. The trial uses AI forecasting models and satellite imagery to identify atmospheric regions where contrail formation is likely. According to Technology Org, the £5 million programme is co-funded by industry partners and the Department for Transport.
