Clean Aviation's third call for proposals, as part of its Phase Two programme, is striving to accelerate climate neutrality in regional aircraft. With a budget exceeding EUR900 million in EU funding for 2022 and 2023 calls, the initiative focuses on ultra-efficient regional and short-medium range aircraft. The governing board's approval of EUR380 million for eight projects is a significant step towards climate neutrality, with projects covering hydrogen-powered and hybrid-electric regional aircraft. Clean Aviation's partnerships with regions like Piedmont, through signed memorandums, demonstrate a commitment to aligning funding with net-zero aviation goals. By emphasizing sustainability in aviation development, Clean Aviation is paving the way for a greener future in the aviation industry.
