Scientists and aviation leaders, including Airbus, are actively researching methods to reduce non-CO2 emissions in aviation. Non-CO2 warming effects from aircraft emissions could be as significant as CO2 emissions but are not yet regulated in the same way. Options being explored include sustainable aviation fuels (SAF), hydrogen propulsion, and operational contrail avoidance. The aviation industry is focusing on mitigating and reducing non-CO2 emissions through different fuel types, propulsion technologies, and operational strategies like modifying flight paths to minimize contrail formation. Airbus is leading around 20 projects related to mitigating non-CO2 emissions, covering areas such as contrail studies, testing fuel alternatives, operational avoidance techniques, and investments in hydrogen-powered flight and innovative propulsion systems. Promising projects like PACIFIC, CRYSTAL, and Blue Condor are part of Airbus' efforts to advance sustainable solutions. Technologies such as humidity sensors are being developed to help aircraft avoid weather conditions conducive to contrail formation. Collaborations with partners aim to accelerate the development and integration of mitigation strategies for non-CO2 emissions into flight operations, contributing to a more sustainable aviation industry.
