How Sustainable Aviation Fuel is Changing the Skies
The aviation industry is one of the largest and fastest-growing sources of carbon emissions, and with international travel and tourism on the rise, there’s increasing pressure to find cleaner ways to fly. One of the most promising solutions? Sustainable Aviation Fuel (SAF).
In this article, we’ll explore how SAF is made, its benefits for climate action, its impact on tourism, the safety factors involved, and what the future holds for aviation fuel.
How is Sustainable Aviation Fuel Made?
Sustainable Aviation Fuel is produced from renewable biomass and waste resources, such as:
- Used cooking oil
- Agricultural and forestry waste
- Algae
- Municipal solid waste
- Non-food crops like camelina or switchgrass
These raw materials go through advanced refining processes, including:
- HEFA (Hydroprocessed Esters and Fatty Acids) – the most common method, using waste fats and oils.
- Fischer-Tropsch synthesis – converts solid waste into fuel using heat and chemical reactions.
- Alcohol-to-Jet (ATJ) – transforms ethanol or isobutanol into jet fuel.
Once processed, SAF is chemically nearly identical to traditional jet fuel. It’s blended (up to 50%) with conventional fuel and can be used in existing aircraft and fueling infrastructure.
How SAF Supports Climate Action
The aviation sector is responsible for about 2.5% of global CO₂ emissions, and that number is expected to grow. SAF helps mitigate this in several ways:
Up to 80% fewer lifecycle emissions compared to fossil jet fuel.
Reduces particulate matter and sulfur emissions, improving air quality around airports.
Promotes circular economy practices by turning waste into energy.
SAF isn’t just a carbon-reducer—it’s a stepping stone toward net-zero aviation by 2050.
ANA – All Nippon Airways is one of many airlines testing biofuel use in aviation in conjunction with airline builders and designers including Boeing. ANA successfully completed the first Trans-Pacific flight utilising biofuel which significantly reduced fuel use and carbon compared to regular aviation fuel.
Many airlines now publish sustainable initiatives on their corporate websites.
Impact on the Tourism Industry
Tourism and aviation are deeply interconnected. As travelers grow more climate-conscious, airlines and destinations embracing SAF can gain a competitive edge. Here’s how SAF benefits tourism:
- Protects climate-dependent destinations (like coral reefs, glaciers, and tropical islands) by reducing environmental stress.
- Aligns with eco-tourism values and enhances brand reputation.
- Encourages sustainable travel policies from governments and tour operators.
- By lowering the carbon footprint of flights, SAF can help make long-haul travel more compatible with climate goals.
Is SAF Safe?
Absolutely. SAF is rigorously tested and certified under the same safety standards as conventional jet fuel.
It’s a “drop-in” fuel, meaning it can be used in current aircraft without modifications.
Airlines like Lufthansa, United, Qantas, and KLM have already operated hundreds of SAF-powered flights.
Blends of up to 50% are already approved, with 100% SAF flights being tested and targeted for certification.
In short, SAF performs just as safely—and sometimes even better—than fossil-based fuels.
The Future of Aviation Fuel
The future of aviation is leaning strongly toward sustainability. Here’s what’s on the horizon:
Increased SAF production: Governments and private sectors are investing heavily in SAF infrastructure.
Policy support: International frameworks like the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) are pushing airlines to adopt low-emission fuels.
Technological innovation: Next-gen SAF production methods (like synthetic e-fuels) and fully electric aircraft are in development.
While SAF alone won’t solve aviation’s climate problem, it’s a critical piece of the puzzle alongside efficiency improvements and smarter flight operations.
Looking to the future
Sustainable Aviation Fuel is a breakthrough in the quest for greener skies. It’s not just a cleaner fuel—it’s a signal that the aviation industry is ready to take real climate action. From protecting fragile ecosystems to supporting the eco-conscious traveler, SAF is transforming how we fly, without grounding our sense of adventure.
If you’re in the tourism or aviation space, now’s the time to explore how SAF can fuel a better future—for your business and the planet.
