## Technical Meaning and Practical Use

SAF book and claim is a chain-of-custody approach that separates the environmental attribute of sustainable aviation fuel from the physical fuel delivery, allowing a buyer to claim an allocated benefit without receiving the same molecules at its departure airport.

Aviation Glossary

**Term:** SAF Book and Claim

**Category:** Sustainable Aviation

## How the Term Is Used

SAF Book and Claim is used in aviation emissions accounting, fuel procurement, environmental regulation or operational planning. The applicable boundary, accounting method and claim basis must be stated clearly.

## Commercial and Reporting Effect

Credible programs need clear accounting, registry controls and safeguards against double counting.

## Claim and Compliance Controls

Environmental claims should identify the underlying methodology, reporting period, registry or regulatory framework and controls against double counting. Physical fuel use, contractual attributes and regulatory compliance are not always the same thing.
