FAQ
How co-claiming works, what makes this pilot different, and why it matters for scaling SAF.
-
Book & claim lets the environmental attributes of SAF be sold and claimed separately from its physical delivery, but the claim itself still sits with a single buyer. Co-claiming goes a step further: it allows that single carbon claim to be shared and validly recognized across multiple stakeholders in the value chain, finance, leasing, manufacturing, airports, fuel suppliers, and more, who all share responsibility for the emissions, without double counting the reduction.
-
It's the first pilot to test co-claiming with real, physical SAF deliveries, two flights between Boston and Amsterdam, rather than in theory. It's co-led by SFC, RSB, and MIT, with operational support from World Energy. It tests the accounting methodology with at least one company representing every activity pool in the value chain.
-
By widening who can pay for and claim the carbon benefit of SAF, co-claiming increases the total capital available to close the price gap with conventional jet fuel. More participants sharing the premium means each carries a smaller share of the cost, producers get a broader and steadier demand signal, and SAF adoption scales faster. Over time, the approach is designed to be applicable across other transport modes and hard-to-abate sectors.
