# Aviation industry contrail and fuel mitigation > Live situation record from CLSTR: https://clstr.news/situations/aviation-industry-contrail-and-fuel-mitigation > Updated: 2026-09-22T16:00:00.000Z. Sources: 8. Developments: 2. Efforts to decarbonize the aviation industry are increasingly focusing on the mitigation of condensation trails, or contrails, which can trap heat in the atmosphere. Research indicates that while a small percentage of flights are responsible for the majority of contrail-related warming, the impact is comparable to CO2 emissions. Technological and operational strategies are being developed to address this. Google has created an artificial intelligence system that uses satellite and meteorological data to predict contrail formation, allowing pilots to make altitude adjustments. Trials with Cathay Pacific showed that avoidance trajectories could reduce the warming effect of contrails by approximately 40%. Broader decarbonization strategies also include the use of Sustainable Aviation Fuels (SAF), such as bio-SAF and e-SAF, which can be used in existing engines. Regulatory frameworks like the European Union’s ReFuelEU Aviation aim to mandate these fuels. Experts suggest that reducing contrail-related warming by half starting in 2030 could delay temperature rises attributable to aviation by roughly ten years. ## Timeline ### 2026-09-22: Aviation decarbonization focuses on sustainable fuels and contrail mitigation Aviation decarbonization strategies are advancing through the use of sustainable aviation fuels (SAF) and the potential mitigation of contrails to delay climate warming impacts. 5 sources. https://clstr.news/cluster/aviation-decarbonization-focuses-on-sustainable-fuels-and-contrail-mitigation ### 2026-09-22: Aviation industry turns to AI to mitigate contrail climate impact Aviation experts and tech companies are using AI to reduce the climate impact of condensation trails by predicting atmospheric conditions and adjusting flight altitudes to prevent heat-trapping contrails. 3 sources. https://clstr.news/cluster/aviation-industry-turns-to-ai-to-mitigate-contrail-climate-impact --- Cite as: Aviation industry contrail and fuel mitigation.
