Unlocking the full value chain for sustainable aviation 

Co-claims for Shared Action (CSA) opens up the carbon claim on SAF to the full aviation value chain, so more stakeholders can pay for it, and more can claim it. 

WHY THIS MATTERS NOW

From market practice to shared rules

Co-claiming isn't a theoretical idea, it is already happening in parts of the market, and it is increasingly referenced in leading guidance as a mechanism the aviation sector will need to formalize.

With research from MIT, in partnership with Smart Freight Centre (SFC) and the Roundtable on Sustainable Biomaterials (RSB), Co-claims for Shared Action builds on the existing SAF certificate system and extends it across more actors in the aviation value chain.

THE CHALLENGE

A premium too large for one actor alone

Sustainable Aviation Fuel (SAF) is widely recognized as the single most impactful lever available to decarbonize air travel, but adoption beyond regulatory compliance depends on someone being willing and able to pay a persistent price premium over conventional jet fuel.

Airlines can't absorb that cost alone, and their corporate customers and cargo shippers have limited budgets too. Scaling SAF means widening who can share the bill, and who can share the credit. 

THE CO-CLAIMS APPROACH

One claim, shared across the value chain

Every actor group in the aviation value chain shares responsibility for the emissions produced across shared operations. Co-Claims gives each of them a credible way to contribute to SAF, and to be recognized for that contribution as adoption grows.

THE RESULT

Coordinated claims, with safeguards against double counting

The result is a market-based approach, complementary to book & claim, that allows a wider set of stakeholders to claim a share of the emissions reduction from the same unit of SAF, coordinated across the value chain and with safeguards against double counting. 

Co-claims for Shared Action (CSA) is building the accounting rules, tracking infrastructure, and financial case to make it work at scale; and, over time, to make it applicable across transport modes. 

THE GOAL

What co-claiming sets out to do


01. DEMAND

Increase demand for SAF by widening the pool of buyers who can help cover the cost.


02. SUPPLY

Increase supply by giving producers a broader, more resilient buyer base.


03. COST

Bring the cost premium down as demand and participation scale.


04. ACCESS

Improve access to SAF for stakeholders who can't buy or claim it under existing mechanisms today.
