SAFc Registry surpasses 500,000 metric tons of CO2e abated

RMI announced Feb. 19 that the SAFc Registry—an independent, not-for-profit registry designed to bring transparency and consistency to the sustainable aviation fuel (SAF) market—has hit a major landmark, surpassing 500,000 metric tons of carbon-dioxide equivalent (CO2e) abated through SAF certificates issued on the platform.

That’s the equivalent of the emissions from a single person traveling round trip from New York’s JFK to London’s Heathrow airport more than 255,000 times.

Launched in 2023 by RMI and Environmental Defense Fund, in collaboration with the Sustainable Aviation Buyers Alliance and Energy Web, the SAFc Registry was created to support air-transport customers in their decarbonization efforts with 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, a milestone sending a clear market signal that corporate demand for lower-emissions air transport and travel can drive real-world production of clean 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, the 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 displacing conventional jet fuel, with outcomes tracked through a public, auditable registry that safeguards sensitive data.

SAF issued and retired on the registry comes from a variety of feedstocks, including tallow, other animal fats and used cooking oil, and meets stringent standards.

“Surpassing this milestone makes clear that companies aren’t waiting on the sidelines—they are demanding high-integrity sustainable aviation fuels,” said EDF Vice President Elizabeth Sturcken. “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’s needed to accelerate investment and scale the clean-fuels aviation needs to achieve net zero.”

Users of the registry range from companies addressing scope 3 aviation emissions, like corporate members of SABA, to airlines and logistics providers.

To date, 17 fuel providers and 21 different production facilities spanning five countries have issued SAFc that has accounted for the emissions reductions of 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’re thrilled by this early milestone and look forward to even more growth as we continue to channel SABA member demand to this best-in-class piece of market infrastructure.”

The high level of trust companies have in the SAFc Registry has helped spur its growth, according to RMI.

The SAFc Registry is governed by a multistakeholder 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 built to provide a user-friendly experience alongside superior transparency.

Every retirement transaction within the registry is validated, stripped of sensitive information and digitally recorded, enabling continuous oversight of registry activity.

This approach supports clear visibility for registry participants, the public and third-party auditors alike.

“Half-a-million tons of CO2 abated proves the SAFc market has traction,” said Ewald Hesse, CEO of Energy Web. “Now the priority is liquidity and scale. Markets move in real time and environmental claims must follow. Continuous, machine-verifiable data replaces static documents and periodic audits, unlocking faster transactions, lower compliance friction and stronger capital flows.”

The continued growth of the SAFc market reflects increasing alignment across corporate buyers, fuel producers and other market stakeholders around the need for trusted, transparent use of SAF to decarbonize aviation, RMI stated.

This milestone highlights the role that credible systems can play in supporting the scale-up of low-carbon fuels and accelerating the aviation sector’s transition toward net zero.
