Google and Embraer join United's Sustainable Flight Fund, exceeding $200 million

United Airlines added new partners including Google, Embraer, and Air New Zealand to its Sustainable Flight Fund, bringing capital dedicated to the sustainable aviation fuel investment vehicle to over $200 million. With aviation accounting for 2-3% of global greenhouse gas emissions, the SAF scaling effort is relevant to Indian airlines and policymakers planning aviation decarbonisation.

United Airlines announced the addition of several new partners to its sustainable aviation fuel (SAF) investment fund, the Sustainable Flight Fund, run by United Airlines Ventures, bringing capital dedicated to the fund to over $200 million. New partners include Aircastle, Safran Corporate Ventures, Embraer, Google, Air New Zealand, HIS, Natixis, and Technip Energies. SAF is seen as a significant tool to decarbonise aviation, which accounts for 2-3% of global greenhouse gas emissions, and is produced from sustainable resources like waste, oils, and agricultural residues.

The aviation supply chain is affected, with the fund's 22 partners spanning aircraft, airlines, engine manufacturers, fuel manufacturers, engineering and technology specialists, investors, and travel management providers. SAF producers estimate the fuels can deliver lifecycle greenhouse gas emissions reductions of as much as 85% compared with conventional fuels. Introduced in 2023, the fund invests in startups focused on SAF research, technology, and production, prioritising innovative technology, unconventional fuel sources, and proven producers to support scaling of SAF supply.

Aviation industry stakeholders should monitor the Sustainable Flight Fund's investments in SAF startups as it works to build supply from conception to commercialisation. United Airlines committed to fully eliminating greenhouse gas emissions by 2050 without relying on carbon offsets, and leads the industry with investments in future production of more than 5 billion gallons of SAF. Airlines and fuel producers evaluating decarbonisation pathways should track how the fund's partner network supports startups with financial and strategic capital to scale fuel supply.
