Scaling sustainable aviation fuel is not just a production challenge — it is equally a governance and trust challenge. That is the premise behind a new three-way collaboration between the International Sustainability and Carbon Certification (ISCC) body, Austrian energy company OMV, and Airbus.

The partnership focuses on Book and Claim chain-of-custody models for SAF. Unlike physical supply chain approaches, Book and Claim systems allow the sustainability attributes of SAF to be claimed independently of where the fuel is physically delivered — helping overcome infrastructure limitations and enabling broader corporate participation in SAF markets.

A key development is Airbus taking on a new role within the ISCC Credit Transfer System: facilitator. In this capacity, Airbus will help broker SAF attribute transactions between supply chain actors, including airlines and corporate sustainability partners. The partners described this as a first-of-its-kind arrangement pairing an aircraft manufacturer as market aggregator with an energy producer and a sustainability certification body.

“Scaling SAF is not only a question of production and demand, but also of trust.” — Dr Norbert Schmitz, Managing Director, ISCC

“Scaling SAF is not only a question of production and demand, but also of trust,” said Dr Norbert Schmitz, Managing Director of ISCC. “Fuel producers, aircraft manufacturers and certification systems each play different roles, but credible and scalable solutions can only emerge when such perspectives come together.”

Representatives from all three organisations presented their findings at the ISCC Global Sustainability Conference in Brussels on February 25, 2026, where the collaboration’s framework and pilot outcomes were discussed before a global audience of SAF market stakeholders.
