SFS — Sustainable Fuel Scheme

The SFS Network Mass Balance

Renewable fuel, allocated efficiently and evidenced transparently.

The Sustainable Fuel Scheme enables eligible renewable fuel introduced at one location in an approved corporate network to support an equivalent certified fuel supply from another location in the same national regulatory jurisdiction. Every renewable quantity is uniquely allocated, supported by physical fuel movements and stock, and subject to verification.

Certified scopes

  • SFS-certified Renewable EN590 DieselNetwork Mass Balance
  • SFS-certified Renewable EN228 GasolineNetwork Mass Balance

One-to-one allocation, no negative credential balance, public certificate validation and periodic verification by the SFS.

How it works

Four controlled steps from renewable input to verified evidence

  1. Step 1

    Renewable fuel enters the network

    Eligible renewable fuel and accepted sustainability evidence enter a defined network.

  2. Step 2

    Quantity recorded in the ledger

    The sustainability quantity is recorded in the SFS credential ledger.

  3. Step 3

    Uniquely allocated to a supply

    An equivalent quantity is uniquely allocated to a physical EN590 or EN228 customer supply within the same national regulatory jurisdiction and network.

  4. Step 4

    Evidence issued and verified

    The SFS issues and verifies an Evidence of Sustainability.

National-grid analogy

Renewable attributes are allocated, not physically traced

A customer on a renewable electricity tariff does not receive electrons traceable to one wind turbine. The renewable generation enters the national grid and an equivalent quantity is allocated to that customer. The SFS applies the same principle to fuel: the renewable attributes are allocated within a controlled corporate network, so the same renewable molecules are not necessarily delivered to the customer.

The restrictions that apply

  • Same national regulatory jurisdiction
  • Defined corporate network
  • Separate EN590 and EN228 pools
  • Physical fuel in and out
  • Closing physical-stock support
  • No duplicate claims
  • Periodic verification by the SFS

Certified products

Two scopes, two permanently separate balances

Eligible renewable fuel and accepted sustainability evidence are held in separate EN590 and EN228 pools within each defined network. Balances are never merged and characteristics are never averaged.

SFS-certified Renewable EN590 Diesel - Network Mass Balance
Renewable diesel components introduced into a defined network support an equivalent certified EN590 supply to a customer in the same jurisdiction and network.

Fuel quality is outside the SFS scope. The SFS certifies sustainability chain of custody only.

SFS-certified Renewable EN228 Gasoline - Network Mass Balance
Renewable gasoline components introduced into a defined network support an equivalent certified EN228 supply to a customer in the same jurisdiction and network.

Fuel quality is outside the SFS scope. The SFS certifies sustainability chain of custody only.
