American Airlines and Google Sign Record 35M Gallon SAF Deal

A Landmark Sustainable Aviation Fuel Agreement

American Airlines and Google have announced a significant Sustainable Aviation Fuel Agreement, marking the largest-ever corporate purchase of sustainable aviation fuel (SAF) certificates. The three-year deal covers 35 million gallons of fuel, which will be physically delivered to Chicago O'Hare International Airport (ORD). By utilizing the SAFc Registry for a book-and-claim model, Google can secure the environmental attributes of the fuel, effectively reducing its Scope 3 aviation emissions by nearly 300,000 metric tons of Carbon Dioxide Equivalent (CO2e).

The Role of Policy and Logistics

The agreement is heavily supported by the Illinois SAF tax credit, provided under the Invest in Illinois Act (SB 2951). This policy offers a $1.50 per gallon incentive for fuel achieving at least a 50% lifecycle greenhouse gas reduction, making the high-cost biofuel economically viable for large-scale adoption. Valero, the fuel supplier, has secured a guaranteed three-year offtake, which provides the revenue certainty required to maintain production levels. According to American Airlines' official newsroom, the partnership serves to catalyze demand and build a more resilient market for alternative fuels.

Strategic Importance of Book-and-Claim

For corporations like Google, the SAFc Registry Book and Claim system is critical to addressing emissions from business travel. Because SAF supply is currently constrained—representing only 0.8% of global aviation fuel use in 2026 according to IATA data—physical uplift on every flight remains logistically impossible. The book-and-claim framework allows the environmental benefits of the fuel to be decoupled from the physical supply chain, enabling companies to invest in the transition toward net-zero targets even when the fuel is not physically present in their specific flight paths. This process is governed by the SAFc Registry to ensure transparency and prevent double-counting of carbon credits.

Industry Context and Market Trends

The aviation sector continues to face significant pressure to decarbonize, yet the production of SAF remains at a fraction of total fuel requirements. In 2026, global SAF production is projected to reach approximately 2.4 million tonnes. By aggregating corporate demand, companies like American Airlines and Google are creating the necessary volume to lower the price premium of SAF, which currently remains two to three times higher than conventional jet fuel. Historically, this model follows the precedent set by earlier partnerships, such as the 2020 Alaska Airlines and Microsoft agreement, which successfully pioneered the use of SAF credits for corporate travel offsetting.

Why This Matters for Aviation Decarbonization

This agreement signals a shift toward institutionalized corporate funding for aviation sustainability. While environmental advocates have previously raised concerns that book-and-claim systems could be perceived as corporate greenwashing, the scale of this 35-million-gallon commitment provides a tangible demand signal to biofuel producers. For the state of Illinois, the deal reinforces its position as a sustainable aviation hub, potentially attracting further investment in fuel infrastructure. The success of this three-year window will likely determine the viability of scaling similar certificate-based models across other major U.S. airports.
