The Governing Board of the Clean Aviation Joint Undertaking has launched €945 million to support 12 visionary projects aimed at decarbonizing aviation. The selected initiatives in the field of new aircraft concepts and innovative propulsion technologies and systems will complement those funded under Clean Aviation’s first and second calls for proposals. Projects will start beginning of 2026 and first flight tests are planned for 2028-2029. The projects will help reduce net emissions of greenhouse gases for commercial air travel by no less than 30% compared to 2020 state-of-the-art technologies, and will pave the way for cleaner aircraft by 2035.

The results of this third call also mark the start of a new cooperation in regional aviation between the EU and Canada: Powerplant Hybrid Application for REegional Segment (PHARES), has been selected to receive €69 million in EU funding. The project, which will advance hybrid-electric propulsion for regional aircraft, is coordinated by a Canadian aircraft engine manufacturer.

“Achieving our climate goals and advancing sustainable aviation can only be done if public and private actors work hand in hand,” says Sabine Klauke, co-chair of the Governing Board, and Airbus’ head of digital design manufacturing and services “Next Gen.” “By supporting the brightest minds, fostering technical excellence and encouraging novel solutions, we can accelerate the breakthroughs our industry needs. The projects selected under Clean Aviation Call 3 represent an important milestone on this journey.”

Overall, 12 projects will receive funding in the following areas:

• €199 million EU funding for ultra-efficient short-medium range aircraft technologies
• €144 million EU funding for ultra-efficient regional aircraft technologies
• €20 million EU funding for fast-track areas (FTAs)
• Transversal projects dedicated to aircraft concept integration and impact assessment have been awarded €15 million EU funding.

Call 3 introduced a new initiative to advance disruptive technologies, the FTAs. FTAs are designed to de-risk alternative or complementary technical solutions offered by research centers and SMEs. They put the focus on proposals that can rapidly advance impactful technologies to the development phase and are closely connected to the short-medium range and regional aircraft coordinators. Four promising projects were selected within this realm.
