Sustainability Framework for Sustainable Aviation Fuel (SAF)
Version 1, adopted by Customer Advisory Board in November 2022


SAFc Registry Guide
We are building a digital sustainable aviation fuel certificate (SAFc) registry with EnergyWeb to bring more transparency and consistency to the emerging SAF certificate market. This quick guide introduces SAFc and the registry.

SAFc Registry Rulebook
The rulebook specifies how SAFc can be issued, transferred, and retired in an independently governed registry. It was developed by RMI and the Environmental Defense Fund, in consultation with the Roundtable on Sustainable Biomaterials (RSB), Sustainable Aviation Buyers Alliance (SABA) members, a consultative group of fuel providers, and other stakeholders.
