Boulder, CO: The SAFc Registry, an independent, not-for-profit platform created to bring transparency and consistency to the sustainable aviation fuel (SAF) market, has crossed a major milestone, surpassing 500,000 metric tons of carbon dioxide equivalent (CO₂e) abated through SAF certificates issued on the platform. That is equivalent to the emissions generated by a single person traveling round trip from New York’s JFK Airport to London’s Heathrow Airport more than 255,000 times.
Launched in 2023 by RMI and Environmental Defense Fund (EDF), in collaboration with the Sustainable Aviation Buyers Alliance (SABA) and Energy Web, the SAFc Registry was developed to support air transport customers in their decarbonization efforts through an easy-to-use, credible, enterprise-grade digital tool for tracking emissions claims.
As of February 2026, the platform has issued SAF certificates (SAFc) representing more than 164,000 metric tons (54 million gallons) of neat SAF. The milestone sends a clear signal that corporate demand for lower-emissions air transport can drive real-world production of cleaner fuels.
“The SAFc Registry has reached a major growth milestone, underscoring its role in translating early market demand into momentum for sustainable aviation fuel,” said Bryan Fisher, Managing Director at RMI. “The registry was designed to deliver the transparency and credibility buyers need to meet climate targets, and this level of uptake demonstrates how verifiable emissions claims through a trusted system can help support the scale-up of low-carbon fuels.”
The abated emissions reflect verified SAF use replacing conventional jet fuel, with outcomes tracked through a public, auditable registry that safeguards sensitive data. SAF issued and retired on the registry comes from various feedstocks, including tallow, other animal fats, and used cooking oil, and meets stringent standards.
“Surpassing this milestone makes it clear that companies are not waiting on the sidelines — they are demanding high-integrity sustainable aviation fuels,” said Elizabeth Sturcken, Vice President at Environmental Defense Fund. “The SAFc Registry is helping turn that demand into credible climate action by ensuring every emissions claim is traceable, verifiable, and grounded in strong environmental integrity. That kind of trust and transparency is exactly what is needed to accelerate investment and scale the clean fuels aviation needs to achieve net zero.”
Users of the registry include companies addressing Scope 3 aviation emissions, such as corporate members of the Sustainable Aviation Buyers Alliance (SABA), as well as airlines and logistics providers. To date, 17 fuel providers and 21 production facilities across five countries have issued SAFc, accounting for emissions reductions for 62 aviation customers, 13 air transport providers, and three logistics service providers.
“Corporate SAF buyers need the right tools to ensure they are getting what they pay for — real carbon reductions from high-integrity fuel, with no questions or confusion about its chain of custody,” said Kim Carnahan, CEO of the Center for Green Market Activation and head of SABA’s Secretariat. “The SAFc Registry meets this critical need. We are encouraged by this early milestone and look forward to further growth as we continue to channel SABA member demand into this key piece of market infrastructure.”
The strong level of trust companies place in the SAFc Registry has helped drive its growth. The registry is governed by a multi-stakeholder board and is intended to complement other SAF market enablers, including standards, accounting guidance, and structured procurement mechanisms.
Energy Web’s decentralized software underpinning the registry is designed to provide a user-friendly experience while ensuring transparency. Every retirement transaction within the registry is validated, stripped of sensitive information, and digitally recorded, enabling continuous oversight of activity. This approach provides clear visibility for participants, the public, and third-party auditors.
“Half a million tonnes of CO₂ abated proves the SAFc market has traction. Now the priority is liquidity and scale,” said Ewald Hesse, CEO of Energy Web. “Markets move in real time, and environmental claims must follow. Continuous, machine-verifiable data replaces static documents and periodic audits, enabling faster transactions, lower compliance friction, and stronger capital flows.”
The continued growth of the SAFc market reflects increasing alignment among corporate buyers, fuel producers, and other stakeholders on the need for trusted and transparent use of SAF to decarbonize aviation. The milestone highlights the role credible systems can play in supporting the scale-up of low-carbon fuels and accelerating the aviation sector’s transition toward net zero.
