We could have called this article “Make Aviation Sustainable Again” and talked about tariffs on kerosene, but we prefer to leave this topic to someone else.

Let’s focus on Sustainable Aviation Fuel (SAF) instead and how it can help sustain aviation.

Aviation’s Climate Dilemma

Aviation connects the world—economically, socially, and emotionally. It powers industries, reunites families, delivers critical aid, and fosters cultural exchange. From tourism and trade to humanitarian relief and emergency transport, aviation plays a vital role in our global society.

Yet, with the freedom to fly comes responsibility. Aviation currently accounts for about 2–3% of global CO₂ emissions, and with demand expected to soar, these emissions could grow unless bold measures are taken. Rather than grounding flights, the industry must decarbonize—and Sustainable Aviation Fuel (SAF) stands out as a breakthrough solution.

Why Aviation Must Sustain—and Transform

Aviation is the backbone of modern society:

Economic Engine: It supports over 87 million jobs globally and contributes trillions in GDP.

Essential Services: It delivers aid, emergency medical transport, and critical logistics.

Global Connectivity: It enables international trade, education, and cultural exchange.

Bridging Gaps: It connects remote regions with vital services and opportunities.

The future of global mobility depends on reducing aviation’s environmental footprint. SAF offers a realistic way to achieve a greener sky without sacrificing the benefits of flight.

What Is Sustainable Aviation Fuel?

SAF is a next-generation jet fuel crafted from renewable or waste-derived sources. It can reduce life-cycle carbon emissions by up to 80% compared to conventional fossil jet fuel and is fully compatible with current aircraft and fueling infrastructure—a true drop-in solution that supports immediate progress.

Types of SAF: Different Routes, Same Destination

Multiple production pathways aim to reduce carbon intensity:

HEFA (Hydroprocessed Esters and Fatty Acids): Derived from waste oils and animal fats; this is one of the most established SAF types.

Fischer-Tropsch (FT): Converts biomass or municipal waste into synthetic fuel via gasification and chemical synthesis.

Alcohol-to-Jet (ATJ): Uses alcohols like ethanol to produce jet fuel, developed by companies such as Gevo and LanzaJet.

Power-to-Liquid (PtL)/E-fuels: Uses renewable electricity, green hydrogen, and captured CO₂—representing a highly scalable long-term solution.

Lignocellulosic Biomass SAF: Produced from agricultural residues and wood waste, ensuring sustainability without competing with food production.

Key Players Driving SAF Forward

Producers

Neste (Finland) – A global leader producing SAF at scale.

TotalEnergies (France) – Adapting refineries, such as La Mède, to produce SAF for European carriers like Air France.

World Energy (USA) – Pioneer with one of the first commercial SAF facilities in the United States.

SkyNRG (Netherlands) – A longstanding SAF innovator across Europe.

LanzaJet, Gevo, Fulcrum BioEnergy, ENI, Aemetis – Companies advancing new technologies across North America and Europe.

Elyse Energy (France) – A dynamic French startup developing the BioTJet project, which transforms forestry residues and end-of-life wood waste—coupled with green hydrogen—into SAF. The project is set to power regional aviation from 2029 onward.

Aircraft & Engine Makers

Airbus & Safran (including Safran Helicopter Engines) (France) – Airbus is pioneering test flights powered by 100% SAF while French group Safran is actively developing solutions for both fixed-wing and rotary-wing aircraft. Notably, Safran Helicopter Engines is at the forefront of certifying and integrating SAF with next-generation rotorcraft engines, ensuring that helicopters too can benefit from cleaner fuel without compromising performance.

Boeing (USA) – Working towards making its fleet fully compatible with 100% SAF by 2030.

Airlines

Air France-KLM, Lufthansa, British Airways, United, Delta – All actively investing in SAF supply contracts and sustainable initiatives.

Governments & NGOs

European Union (ReFuelEU Aviation): Mandating a 2% SAF blend in aviation fuel as a starting point, rising to 6% by 2030.

France’s SAF Mandate: One of the first national regulations requiring SAF use, now aligned with EU targets.

France’s SAF Strategy: Leading by Example

France is positioning itself as a European leader in sustainable aviation. By integrating SAF into its national energy and environmental strategies, the French government has established clear targets:

Blending Mandate: Under the ReFuelEU framework, France is enforcing a SAF blend of 2% in 2025, increasing to 6% by 2030. This regulation ensures consistent progress toward decarbonization and fosters domestic SAF production.

Industrial Transformation: Projects such as TotalEnergies’ La Mède and Elyse Energy’s BioTJet are setting new standards in domestic fuel production.

Innovation and Partnerships: With strong cooperation between government bodies, research institutions, and industry leaders like Airbus and Safran, France is pioneering advancements in SAF technology and policy.

This forward-thinking strategy not only mitigates climate impact but also stimulates economic growth and technological leadership.

---

When Will Aircraft Fly on 100% SAF?

Presently, commercial aircraft are certified for up to a 50% blend of SAF with conventional jet fuel. However, the industry is rapidly progressing toward full utilization:

Airbus has successfully tested flights powered entirely by SAF.

Boeing is targeting full SAF capability for its fleet by 2030.

International certification bodies are streamlining approval processes for 100% SAF operations.

Key challenges remain—ramping up production, reducing costs, and building a secure global supply chain—but momentum is undeniable. The transition is well underway.

Heeding Climate Solutions: Our Commitment to SAF—and Aviation

At Heeding Climate Solutions, we view SAF as one of the most powerful tools in combating aviation’s carbon footprint. We deeply care for aviation in all its forms—whether it’s commercial airliners, military aircraft, fixed-wing airplanes, or rotary-wing helicopters. Our efforts include:

Trade: through our digital platform for corporate acocunts.

Promotion: Pushing for robust mandates and incentives that drive SAF uptake.

Public Engagement: Informing and inspiring consumers, policymakers, and industry leaders about the benefits of SAF.

Collaborative Partnerships: Working closely with fuel producers, airlines, and research experts to innovate and implement sustainable practices.

We are not merely observing this transformation—we are actively shaping it because we believe every flight matters.

Conclusion: Clear Skies Ahead

Sustainable Aviation Fuel is a cornerstone of a cleaner, more resilient future for aviation. By replacing fossil fuels with renewable alternatives, SAF offers a realistic way to balance the enormous social and economic benefits of flight with the urgency of climate action.

The technology is here, the players are committed, and the regulatory framework—embodied by initiatives like ReFuelEU and France’s ambitious SAF strategy—is solidifying. This is the moment to accelerate the transition to sustainable skies.

Let’s take off—together—for a future marked by innovation, responsibility, and clear skies.
