Book & Claim (SAFc)

Add SAFc to your fuel procurement and aviation decarbonization strategy, even when physical SAF is unavailable or impractical across parts of your operating network.

Expand access to SAF with Book & Claim (SAFc) Solution

Book & Claim(SAFc) gives operators a practical way to purchase SAF certificates (SAFc) for eligible activity without requiring physical SAF delivery at every operating location.

Physical SAF need not be available at every airport in your network for your organization to participate. Physical SAF is delivered at an eligible location, and the associated environmental attributes are documented and allocated to your organization under the applicable program rules. This extends SAF participation to locations where physical supply is unavailable or impractical, while myWorld Decarbonize, chain-of-custody documentation, and specialist support help connect the purchase to your fuel-burn data, reporting needs, and intended use.

How Book & Claim (SAFc) supports aviation decarbonization

Extend SAF participation across more of your operating network when physical supply is unavailable or impractical.
Use a consistent Book & Claim (SAFc) process to coordinate eligible activity across locations or business units.
Match physical SAF and Book & Claim SAFc to each location based on volume, timing, availability, and reporting requirements.
Support internal records and reporting with the applicable chain-of-custody documentation, retirement statement, and certificate.
Give procurement and operations teams a shared basis for volume, reporting, and documentation decisions.

Book & Claim basics

What is Book & Claim (SAFc)?

Participate in SAF without requiring the physical fuel to reach every aircraft or operating airport.

Book & Claim (SAFc) is a chain-of-custody mechanism that separates physical fuel delivery from the allocation of eligible environmental attributes. Physical SAF enters the aviation fuel supply chain at one location, while its associated attributes are recorded and allocated separately. This allows customers to purchase SAFc without requiring the same physical fuel to be delivered into their aircraft at every operating airport.

Purchase process

Turn verified aviation data into Book & Claim (SAFc) certificates

Move from operating activity and fuel-burn data to a documented SAFc purchase.

Start by identifying the flights or operating activity, fuel volume or fuel-burn data, reporting period, and organization that will hold the claim. A SAFc specialist can help determine the appropriate volume and purchasing route. myWorld Decarbonize calculates emissions from fuel burn and supports SAFc purchases through myWorld. Once the purchase is processed, the retirement statement and certificate provide the supporting transaction record and can include flight details, carbon intensity, delivery airport, and feedstock information associated with the physical SAF.

Book & Claim (SAFc) FAQs

Find answers about eligibility, documentation, calculations, and reporting before purchasing sustainable aviation fuel via Book & Claim (SAFc).

How is my fuel burn calculated?

myWorld Decarbonize allows users to easily calculate their carbon usage based on fuel burn. World Fuel’s proprietary algorithm calculates fuel burn using various attributes, including weather, aircraft specifications, and historical data, to provide one of the most accurate fuel burn calculations available online.

How are my emissions calculated?

To calculate the emissions associated with every gallon of jet fuel burned, we used the lifecycle analysis CORSIA baseline of 89 gCO₂e/MJ or 11.81 kgCO₂e/gal. Of this, 15 gCO₂e/MJ (1.99 kgCO2e/gal) are associated with upstream production and transportation emissions, sometimes referred to as well-to-tank or Scope 3 emissions of the fuel. 74 gCO₂e/MJ (9.82 kgCO₂e/gal) are associated with fuel combustion, sometimes referred to as tank-to-wake or Scope 1 emissions of the fuel. Fuel emissions are sometimes represented by the associated Scope 1 emissions only and not the full Life Cycle Analysis (LCA) value. We use the CORSIA-established LCA because it more accurately reflects the total emissions associated with every gallon of fuel consumed and can be consistently applied for all jet fuel, regardless of the source and location of production.

Carbon offsets vs. insets

Carbon offsets and carbon insets are two strategies used to mitigate carbon emissions, but they operate differently.

Carbon offsets involve compensating for emissions by funding projects that reduce or remove greenhouse gases elsewhere. Examples include reforestation projects or renewable energy initiatives. Carbon insets, on the other hand, focus on reducing emissions within a company’s own value chain. This means implementing sustainable practices directly related to the company’s operations, such as improving supply chain processes or investing in renewable energy for their facilities

Book and Claim is an example of a carbon inset because it allows companies to reduce emissions within their own value chain by purchasing SAF credits, thereby embedding sustainability directly into their operations.

What should I expect after purchasing SAF via Book and Claim?

After your purchase has been processed, World Fuel will produce a retirement statement and certificate. This could take up to 72 hours, not including holidays and weekends. The statement will include flight details as well as details on any associated fuel specs such as carbon intensity, airport of delivery, and raw materials used in production.

How were my emissions savings from the SAF I purchased today calculated?

The emissions savings calculated on your certificate use the CORSIA calculation for emissions reductions found in “An Overview of CORSIA Eligible Fuels (CEF)”, published by the ICAO Secretariat. Pictured is the formula used in the CORSIA calculation for tank-to-wake Scope 1 emissions. Your emissions reductions were calculated using the IATA-recognized Fuel Conversion Factor of 3.84 for well-to-wake Scope 1 and Scope 3 emissions reductions.

Discuss your Aviation decarbonization strategy

Determine how physical SAF, Book & Claim (SAFc), or a combined approach could fit your operating network, reporting needs, and procurement plan.

Provide your operating network, fuel-burn or volume data, reporting period, and intended SAFc use. A SAFc specialist can evaluate physical SAF, Book & Claim (SAFc), and a combined approach against those requirements and identify the documentation needed for the intended purchase and claim.
