The SAFc Registry, an independent not-for-profit platform aimed at improving transparency in the sustainable aviation fuel (SAF) market, has surpassed 500,000 metric tonnes of carbon dioxide equivalent (CO₂e) abated through SAF certificates issued on the system.
Launched in 2023 by RMI and Environmental Defense Fund (EDF), in collaboration with the Sustainable Aviation Buyers Alliance (SABA) and Energy Web, the registry enables companies to track and verify emissions reductions linked to SAF use. As of February 2026, it has issued certificates representing more than 164,000 metric tonnes (54 million gallons) of neat SAF.
Bryan Fisher, Managing Director at RMI, said the milestone underscores the platform’s role in converting early demand into momentum for SAF. “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,” he said.
The recorded emissions reductions reflect verified SAF displacing conventional jet fuel. Fuels listed on the registry are derived from feedstocks including tallow, animal fats and used cooking oil, and must meet established sustainability standards. Transactions are recorded through Energy Web’s decentralised software, allowing public auditing while protecting commercially sensitive data.
Elizabeth Sturcken, Vice President at EDF, said the milestone showed that “companies aren’t waiting on the sidelines — they are demanding high-integrity sustainable aviation fuels”. She added that the registry ensures emissions claims are “traceable, verifiable, and grounded in strong environmental integrity”.
To date, 17 fuel providers and 21 production facilities across five countries have issued SAF certificates through the platform. These have supported emissions reductions claims for 62 aviation customers, 13 air transport providers and three logistics service providers.
Kim Carnahan, CEO of the Center for Green Market Activation and head of SABA’s Secretariat, said corporate buyers require assurance that they are securing genuine carbon reductions. “The SAFc Registry meets this critical need,” she said.
Ewald Hesse, CEO of Energy Web, said the next priority for the market 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,” he said.
