Sustainable Aviation Fuel (SAF) – where we’re at in 2025

Why SAF matters more than ever

As the aviation industry races toward net-zero emissions by 2050, Sustainable Aviation Fuel (SAF) has emerged as the most promising near-term solution.

SAF can reduce lifecycle carbon emissions by up to 80% compared to conventional jet fuel, making it a cornerstone of sustainable travel.

But where are we at with SAF today?

Let’s explore the current landscape of SAF production and what it means for the future of global travel…

SAF Production: A rapidly expanding frontier

This year, SAF production is gaining some serious momentum, especially in the United States.

U.S. SAF capacity has rocketed from just 2,000 barrels per day early last year to more than 30,000 today.

And there are some big projects in the pipeline.  

Phillips 66 in Rodeo, California is producing 10,000 barrels a day, while Diamond Green Diesel in Port Arthur, Texas is notching 15,000.

Globally, SAF production topped a huge 1.25bn litres last year, doubling the total from 2023, but it still only accounts for 0.3% of total jet fuel use.

But how is SAF made?

Currently, there are 11 American Society for Testing and Materials (ASTM) approved production pathways for SAF and they include HEFA (Hydroprocessed Esters and Fatty Acids) which is the most common method, using waste oils and fats.

There’s also FT-SPK (Fischer-Tropsch Synthetic Paraffinic Kerosene) which is derived from biomass or municipal waste.

And there is Alcohol-to-Jet (ATJ) which converts ethanol or isobutanol into jet fuel.

These fuels are drop-in ready, meaning they can be blended with conventional jet fuel and used in existing aircraft without modification.

Are there incentives and support available for SAF production?

Government incentives are playing a crucial role in scaling SAF.

In the U.S., Renewable Fuel Standard (RFS) and federal tax credits are driving investment, while ReFuelEU Aviation mandates SAF blending targets across the EU.

Corporate demand is well and truly rising, with airlines and travel buyers committing to SAF purchase agreements.

What does this mean for travellers?

For One Global clients, SAF represents a tangible way to reduce the carbon footprint of business and leisure travel.

While SAF is still more expensive than traditional fuel, growing production and policy support are expected to narrow the cost gap over the next decade.

Looking Ahead

While the SAF industry is still in its early stages, 2025 marks a turning point. With production increasing, technology maturing and global demand rising, SAF is no longer a niche solution -it’s the future of sustainable aviation.
