Second-phase scaling adds collaboration with Contrails.org to support broader research on operational feasibility across Asia and transpacific routes.
Hong Kong–Singapore interventions generated over 50% of the trial’s total estimated emissions reductions.
Google launched an Asia-Pacific contrail-avoidance trial with Cathay Pacific to cut aviation’s climate impact from persistent contrails.
More than 80 flights used revised routes, delivering an estimated 40% reduction in contrail warming impact based on satellite analysis.
The program targets over 100 flights across Cathay’s network, focusing on small altitude changes guided by AI forecasts.
