Sustainable Aviation Buyers Alliance Launches Advanced, Next-Generation SAF Procurement DEADLINE August 29, 2025

(Sustainable Aviation Buyers Alliance) SABA's third RFP seeks to leverage corporate demand to help move a next-generation SAF facility to final investment decision. -- Today (May 6, 2025), the Sustainable Aviation Buyers Alliance (SABA) released a request for proposal (RFP) to increase the supply of next-generation sustainable aviation fuel (SAF), including power-to-liquids and those using advanced bio-based feedstocks. This first-of-its-kind aggregated SAF procurement is designed to deliver a much-needed boost to scalable long-term SAF production capacity. By focusing the RFP on next-gen fuels, SABA seeks to channel investment toward SAF with fewer feedstock constraints than today's commercially available fuels, enabling more effective long-term decarbonization of the aviation sector.

SABA members include over 35 companies from a broad range of sectors, including finance, technology, media and entertainment, business consulting, and others seeking to reduce their aviation emissions through investment in sustainable aviation fuel. Through this RFP, SABA will facilitate 5 to 10-year forward purchasing commitments on behalf of its members at sufficient volumes to support final investment decision (FID) for a new next-generation SAF production facility.

"The SAF market is growing rapidly but the technologies we need to fully decarbonize the aviation sector are still in their infancy," said Kim Carnahan, CEO of the Center for Green Market Activation and head of SABA Secretariat. "Investment needs to happen now if we want these technologies to scale post-2030 and keep the aviation sector on track to meet its long-term net zero goals."

SAF represents the best near-term opportunity to decarbonize aviation as it is a drop-in fuel that can be used in today's aircraft fleet. Despite significant recent growth, SAF still makes up less than 1% of total aviation fuels used today with the market dominated by SAF made from traditional feedstocks, such as waste oils, that face limitations to scale beyond 2030. SAF with the greatest scalability potential, using feedstocks such as renewable hydrogen, agriculture and forestry residues, and municipal solid waste, is only a small portion of the currently available SAF. Without focused investment today, these fuels may not be available in the quantities needed to meet global decarbonization objectives.

SABA is working with its corporate partners to generate the demand signal needed to give advanced SAF producers confidence to scale production. Through a book and claim model, corporate customers will be purchasing sustainable aviation fuel certificates (SAFc) that allow them to invest in SAF and capture the environmental benefits, even if the fuel does not flow directly into the planes they fly on. The travelers' investment allows them to make a greenhouse gas emissions reduction claim on their climate disclosures, while the physical SAF flows to an aircraft operator.

"Book and claim is the bridge between the aviation industry's sustainable fuel ambitions and scalable real-world production — and SABA is helping build it," said Bryan Fisher, Managing Director at SABA co-founder RMI. "By mobilizing corporate demand and catalyzing investment in cutting-edge fuel production, we can fast-track innovation, expand high-integrity supply, and deliver the climate results the aviation sector urgently needs."

Since SABA's launch in 2021, it has helped channel approximately $200 million total SAF investment: first through a 2021 proof of concept pilot procurement for a short-term offtake period, followed by 2023-2024's groundbreaking multi-year procurement involving 27 participants and supporting approximately 50 million gallons of SAF. Through the RFP announced today, SABA is targeting longer-term offtakes to help plants get to FID by 2026 and be operational by 2030.

"This RFP is an opportunity for corporate leaders, forward-looking airlines and next generation fuel producers to work together toward a truly net-zero aviation sector," said Elizabeth Sturcken, Vice President at Environmental Defense Fund, a SABA co-founder. "We must be strategic in how we grow the SAF market with environmental integrity so that we can decarbonize the aviation sector without placing new demands on limited feedstocks or land resources that may create new environmental problems."

By participating in this next-gen procurement, SABA members will be able to meet their emission reduction targets for air travel and air freight through advanced purchases of SAFc connected to next-gen SAF meeting SABA's rigorous sustainability criteria.

While the RFP announced today is focused on next generation SAF, SABA continues to support its members in purchasing high-integrity commercially available SAF.

The Sustainable Aviation Buyers Alliance (SABA) is a joint initiative of RMI and Environmental Defense Fund, with expert support from the Center for Green Market Activation, focused on accelerating the path to net-zero aviation by driving investment in, and adoption of, high-integrity sustainable aviation fuel (SAF) and supporting companies, airlines, and freight customers in achieving their climate goals.
