Cathay Pacific (HKG:0293) and Google are partnering to research and trial AI-powered technology to reduce the climate impact of aircraft contrails, the companies said in a statement Monday.
An initial trial that began in late 2025 covered more than 100 flights, with over 80 using contrail-avoidance routes. Google estimates those flights reduced the warming impact of contrails by about 40%.
The companies will now expand trials across Cathay's Asia and transpacific network to gather more operational data and assess the feasibility of deploying contrail avoidance at scale.
