Flying Greener: SAF
Understanding the Growing Need for Sustainable Aviation Fuel
As airlines aim to reduce their carbon footprint, sustainable aviation fuel (SAF) is becoming increasingly important. By 2050, SAF demand could rise dramatically, from today's small amounts to possibly over 500 million tonnes per year. This substantial increase highlights the aviation industry's urgent effort to lower greenhouse gas emissions and combat climate change.
Where We Stand Today
In 2024, airlines globally used about 1 million tonnes of SAF, making up only around 0.3% of total jet fuel consumption. By 2025, usage is expected to double to 2 million tonnes, but this amount still represents less than 1% of overall jet fuel demand.
Even though these amounts are relatively small, the economic impact is significant. SAF currently costs between two to five times more than traditional jet fuel, translating into billions of dollars in additional annual costs for airlines. This pricing premium presents a significant barrier but underscores the industry's commitment to environmental responsibility.
Why Demand is Growing: Policies Lead the Way
Several government policies and international frameworks are driving future SAF growth:
EU (ReFuelEU Aviation): This regulation requires airlines to blend 2% SAF into their fuel by 2025. This requirement increases to 6% by 2030 and escalates sharply to 70% by 2050. By 2030 alone, this translates to approximately 2.8 million tonnes of SAF per year. These stringent requirements indicate the EU's strong commitment to sustainable aviation.
U.S. SAF Grand Challenge: In the United States, the SAF Grand Challenge sets ambitious targets of 11 million tonnes annually by 2030, rising dramatically to as much as 133 million tonnes per year by 2050. These goals are designed to rapidly accelerate the scale-up of SAF production and use across the aviation industry in the U.S.
ICAO Global Framework: The International Civil Aviation Organization (ICAO) aims for a 5% reduction in aviation fuel carbon emissions by 2030. This global target implies the need for around 20 million tonnes of SAF worldwide, reinforcing international cooperation and commitment.
These policy measures include penalties for non-compliance, such as fines or restrictions, ensuring airlines have a strong incentive to meet these SAF targets.
Corporate Promises: Ensuring Future Demand
In addition to governmental mandates, airlines and corporations have proactively committed to buying substantial quantities of SAF through long-term agreements. To date, over 50 billion liters (approximately 40 million tonnes) of SAF have been contracted, with terms extending up to 15 years.
Major airlines, notably United Airlines, have led the charge by investing billions of liters in future SAF production. Such significant investments guarantee producers a stable demand, thus encouraging further development of production capacity and infrastructure.
Facing the Supply Challenge
Despite rapidly increasing demand, SAF production capacity isn't scaling quickly enough. By 2030, global SAF production might reach approximately 15 million tonnes, still falling short of the 23 million tonnes mandated by various policies.
Several critical challenges hinder the rapid growth of SAF production:
Feedstock Availability: Current SAF production relies heavily on feedstocks such as waste oils and fats, which are also highly sought after by other biofuel markets. This competition limits supply availability and raises costs.
Technology Development: Newer technologies like Alcohol-to-Jet (ATJ) and synthetic e-fuels show great promise but remain relatively undeveloped commercially. Significant research and investment are still required to make these methods widely viable.
Investment Risks: The considerable upfront investment needed for SAF production facilities requires stable, predictable policies and secured long-term contracts to attract investors. Uncertainty in policies or market stability can significantly deter investment.
What This Means for the Industry
Producers and Investors: Clear, long-term demand driven by policy mandates and corporate contracts provides strong incentives for investments in new SAF production facilities and innovative technologies. Investors are likely to focus on scalable, efficient solutions and sustainable feedstocks.
Airlines: As airlines increasingly rely on SAF, effectively managing higher fuel costs becomes essential. They may need to share these increased expenses with passengers through ticket pricing or collaborate with corporate partners committed to reducing their carbon footprint.
Policy Makers: Clear, consistent, and stable regulations, alongside financial incentives such as tax credits or subsidies, are essential for supporting continued investment and growth in SAF production. Policymakers must balance ambitious environmental goals with realistic market conditions to sustain momentum.
The Future of Flying Green
Sustainable aviation fuel has rapidly transitioned from an optional niche product to a vital element in aviation sustainability strategies. With firm policy commitments and significant corporate backing, the critical challenge now isn't whether SAF will expand but rather how quickly and efficiently production can scale up to meet rising demand.
The next decade will be decisive for the aviation industry. Airlines, fuel producers, investors, and policymakers who successfully navigate this s
hift will gain a vital competitive edge in an increasingly carbon-conscious global economy, leading the way in aviation sustainability.
