Why there is no list price
A SAF certificate records the verified environmental attributes of one specific batch of fuel, so its cost follows that batch. What the fuel was made from, how it was made, who certified it and where it was delivered all move the number. Two certificates can be equally valid and priced differently, for the same reason two valid insurance policies are.
That is why this page explains the drivers rather than quoting a figure. A number without its batch behind it would tell you very little, and it would be out of date by the time you read it.
The four drivers
Feedstock
Most SAF today is made from used cooking oil and tallow, and waste feedstocks have their own supply constraints: there is only so much of them. Scarcer inputs cost more, and the report we published with PA Consulting maps how those constraints shape the market.
Pathway
HEFA fuel from waste oils is the established route. Newer pathways, e-SAF above all, come with the costs of first-of-a-kind plants and depend on cheap renewable electricity. Their fuel is dearer while the technology scales.
Certification and evidence
A certificate that survives an audit rests on a certified chain of custody, an independent registry entry and a retirement statement. That evidence chain is part of what you are paying for, and a cheaper claim without it is not the same product.
Commitment
Volume and duration move price in this market as in any other. Producers value firm, multi-year demand, and price it accordingly.
The premium, plainly
SAF costs more than fossil jet fuel, and we won’t pretend otherwise. On EASA’s reference prices, bio-based SAF stood at 2.84 times the price of conventional jet fuel in 2024 and 3.01 times in 2025. Absolute prices have fallen; the ratio has not closed.
The honest frame is what the premium buys. A retired certificate gives you a verified, registry-backed reduction inside your own value chain, with documentation an auditor can trace from the batch to your claim. The premium is also the demand signal this market runs on. Firm corporate demand can give producers the confidence to invest in future capacity, and that is how supply grows over time.
Getting to an actual number
A real quote needs three inputs: the footprint you are addressing, the scope you would claim against, and the volume and duration you can commit to. With those, the conversation is short, and the number comes with the batch evidence attached. That is the conversation to start with us, and the corporate buyer’s guide covers what to establish internally first.
