Zemo Partnership Renewable Fuels Assurance Scheme (RFAS)
Independently verifies claims made by companies supplying renewable fuels to HGVs and equipment operators.
Type of scheme
Certification and accreditation
Greenhouse gas emissions
The Renewable Fuels Assurance Scheme (RFAS) has been developed to enable vehicle fleet operators to have independent assurance of the greenhouse gas emission and feedstock sustainability performance of high blend renewable fuels sold in the UK.
The scheme aims to verify claims made by companies supplying renewable fuels regarding their product’s GHG emission savings and provenance of raw material feedstocks. The RFAS works alongside the Government’s Renewable Transport Fuel Obligation (RTFO), providing a mechanism for guaranteeing that fleet operators are purchasing bulk supplies of sustainable low carbon fuels.
The scheme will facilitate fleet operators receiving renewable fuel supply chain specific GHG emission data, thereby ensuring accurate and representative information for company carbon reporting1 (Scope 3 Emissions). Furthermore, credible GHG emission data will help inform decision making processes regarding vehicle fleet decarbonisation options by demonstrating the merits of sustainable low carbon fuels.
The objectives of the scheme are:
- To encourage greater use of renewable fuels by heavy-duty vehicle operators and establish a unique approach to raising the profile and credibility of sustainable low carbon fuels
- To ensure the provision of reliable, accurate, robust and transparent GHG emissions data reported to vehicle fleet operators by renewable fuel suppliers
- To give independent assurance of the GHG emissions and sustainability performance of high blend renewable fuels available supplied to the heavy-duty vehicle sector
