Zemo Partnership has launched RFAS Aviation, a new voluntary assurance scheme designed to provide independent verification of Sustainable Aviation Fuel (SAF) across the UK supply chain. The scheme responds to a critical industry need for a harmonised approach to verifying SAF traceability in the downstream fuel supply chain.

The absence of a consistent mechanism has limited the ability of airline operators to demonstrate greenhouse gas (GHG) emissions reductions under the UK Emissions Trading Scheme (ETS), and for fuel suppliers to robustly evidence SAF sustainability credentials to customers.

RFAS Aviation builds on the established Renewable Fuels Assurance Scheme (RFAS), widely used in the road transport sector, extending its proven audit and assurance framework into the aviation market and aligning with UK ETS sustainability and chain-of-custody requirements.
