Hong Kong Carrier Partners With Google On Climate Impact Reduction

Cathay Pacific and Google are expanding trials of an AI-powered technology designed to help cut climate-warming aircraft contrails. The trial, which began in late 2025, uses Google’s AI-based forecasting tools to identify areas where contrails are likely to form and help pilots adjust flight altitude accordingly. An initial test on more than 80 Cathay flights achieved an estimated 40% reduction in contrail warming impact. The partnership aims to research how predictive AI can be deployed in live operations to help address the climate impact of contrails. This development was first reported by Reuters.
