Guidance

Voluntary schemes that can be used to support claims made under the RTFO and SAF Mandate

Updated 27 November 2025

Suppliers can use any of the listed voluntary schemes to support claims of compliance with the Renewable Transport Fuel Obligation (RTFO) or Sustainable Aviation Fuel (SAF) Mandate.

If using a voluntary scheme to support their applications, suppliers must be aware that additional information or evidence from all stages of the supply chain must be provided to verify that fuel meets the requirements of the RTFO or SAF Mandate, if requested from the administrator. This can include requesting information or evidence for the entire supply chain and each link in the chain of custody to demonstrate that the feedstock and production processes comply with the RTFO or SAF Mandate’s sustainability requirements.

Voluntary schemes

All the voluntary schemes listed in this table have demonstrated they have good quality audit processes, and all can be used to support claims relating to biofuels.

The table shows which schemes could also be used to support claims relating to biomethane, as well as specifying the scope of the different schemes as relates to feedstocks, geographical coverage, chain of custody and whether there are important scope limitations in terms of the land criteria or greenhouse gas criteria.

Some voluntary schemes may not cover all the RTFO or SAF Mandate required criteria, especially for certain fuel types.  In these cases, a scheme will only be accepted as providing supporting evidence for the criteria mentioned in the table. Further evidence is required to demonstrate compliance with the criteria not covered, as described in the footnotes to the table.

1. For biomethane, the RTFO requires carbon intensity calculations to be undertaken on an individual feedstock basis and does not allow the emissions from soil carbon accumulation factor for manure to be applied. For biomethane traded across a gas grid, suppliers will need to provide evidence of the physical flow of gas in the form of grid capacity bookings at cross border interconnection points, in line with the RTFO Biomethane Guidance. ↩

2. ‘Soil carbon criteria’ refers to the criteria referenced in Sections 9.14 - 9.16 of the  RTFO guidance. ↩ ↩² ↩³ ↩⁴

3. The scheme provides information on the location of the farm which enables the fuel supplier to calculate GHG emissions based on NUTS2 values. ↩ ↩² ↩³
