The Sustainable Fuel Register is an industry led register of non-wood based fuels and provides participants (suppliers, traders and end users) with a simple way of meeting sustainability criteria. SFR considers three types of participant (Producers, Traders and End Users) although in many cases participants could be a combination of types, even for the same fuel. Registering on the SFR provides you with an easy and affordable route to ensuring the fuels you use and sell are sustainable and compliant.
