The aviation industry, in collaboration with Airbus and other leaders, is actively investigating ways to reduce non-CO₂ emissions in aircraft operations. Contrails and other non-CO₂ emissions contribute significantly to aviation's overall climate impact, sparking a policy debate on regulating these emissions. Various projects, including PACIFIC and CRYSTAL, explore fuel alternatives like sustainable aviation fuels and hydrogen propulsion. Airbus is engaged in around 20 projects focusing on contrail avoidance, operational mitigation, and new technologies. Initiatives like CICONIA aim to forecast contrail-prone weather and optimize flight paths, while projects like Blue Condor are testing hydrogen-powered flight systems. Promising technologies such as humidity sensors are being developed to help aircraft avoid conditions conducive to contrail formation. These efforts aim to accelerate the integration of mitigation strategies for non-CO₂ emissions into flight operations, ultimately contributing to the aviation industry's sustainability goals.
