Global airline alliance oneworld and its member airlines, along with Bill Gates-backed Breakthrough Energy Ventures (BEV), have introduced a new $150 million fund aimed to address the limited availability and high cost of sustainable aviation fuel (SAF). In a statement, released on September 17, 2025, the airline alliance said Bill Gates’ Breakthrough Energy Ventures (BEV) would serve as the fund’s capital investment manager. The fund is also supported by oneworld alliance member airlines such as International Airlines Group (IAG), Cathay Pacific, and Japan Airlines. Both oneworld and Breakthrough Energy Ventures have also decided to include non-alliance investors, like Singapore Airlines. The global aviation sector generates approximately $4.1 trillion in economic activity and supports 86.5 million jobs.
