The Promise of SAF
Air freight is one of the fastest growing logistics segments, and its energy transition now leans heavily on sustainable aviation fuel, often called SAF. When used without blending, SAF can shrink lifecycle greenhouse gas output by roughly eighty percent compared with conventional jet fuel. Crucially, it already fits within existing engines, pipelines and refuelling trucks, so no fresh infrastructure is required. The International Air Transport Association projects that SAF could deliver almost two thirds of the reduction the sector must achieve on the pathway to net zero.
How Book and Claim Unlocks Scale
Today fewer than one in two hundred airports regularly store SAF. Rather than waiting for every location to catch up, the book and claim model separates physical fuel delivery from environmental benefit allocation. An authenticated record is created when SAF is pumped into any aircraft. Airlines or shippers elsewhere can then buy the associated emissions reduction certificate and retire it against their own flights, receiving auditable proof through a digital registry. The mechanism therefore mobilises global demand immediately, which encourages producers to build larger plants and ultimately drives prices lower.
Blockchain Adds Confidence
Platforms like Avelia record each certificate on blockchain ledgers that cannot be altered. That transparency helps accountants, regulators and customers verify that a single litre of SAF produces just one tradable credit. As a result even companies that rarely move cargo by air can now participate confidently in the transition by purchasing fractional credits.
Non-obvious insight
Because book and claim transactions reveal real time willingness to pay, the aggregated data set is becoming an unexpected demand forecasting tool for fuel refiners. Early analytics already show weekend spikes in certificate purchases, hinting at a future where production schedules mirror e commerce activity rather than airport traffic.
Conclusion
Sustainable aviation fuel already works technically. Book and claim, reinforced by blockchain, makes it work commercially too. Collaboration across shippers, airlines and digital platforms can accelerate volume, reduce cost and place cleaner air freight within reach for every customer.
