The emissions you generate, addressed where the fuel is.

The emissions from the fuel you burn are yours, and the fuel is not always where you need it. Book and Claim lets you fund certified supply where it exists, and retire the reduction against your own Scope 1 emissions. Audited from fuel to certificate, and counted once.

  • Deal with the emissions you actually generate

    A Scope 1 reduction against the emissions you generate directly, externally audited and settled on a registry. The reduction is retired once, to you, on a publicly auditable register.

  • Act even where no SAF is available

    Sustainable fuel is scarce, and not always available at the airports you fly from. Book and Claim separates the certified reduction from the physical fuel, so you're not waiting on supply at your own hubs.

  • Voluntary volume, above the mandate

    We support airlines with voluntary sustainable fuel purchases, beyond what any blending mandate already puts in the fuel supply, so the reduction is genuinely additional.

  • Secure supply before it tightens

    We sign the long offtake a producer needs to build, then bring the attributes to market. That's a route to credible volume in a market where announced capacity keeps moving.

The other side of the trade

One batch of fuel, two positions.

The sustainable aviation fuel (SAF) you buy voluntarily has two attributes. The Scope 1 reduction is yours, against the fuel you burn. The Scope 3 attribute has value to the corporates who fly with you, and we bring those buyers to the table.

Selling the Scope 3 attribute onward reduces your net cost of SAF. That's the point of the model: corporate demand helps cover the premium, so acting early costs less than it first appears, and the scale-up gets funded from both sides.

The fuel goes where it makes sense. The reduction comes to you.
