The aviation industry is on the brink of a transformative shift as it strives to achieve net-zero carbon emissions by 2050. At the heart of this transition is Sustainable Aviation Fuel (SAF), which has emerged as a crucial tool in reducing the sector’s carbon footprint. European initiatives are reshaping the aviation industry but financing is critical in realizing these ambitions quickly. But, how to finance aviation’s sustainable future today?
SAF, derived from renewable feedstocks such as agricultural waste, algae, and power-to-liquid technologies, offers up to an 80% reduction in lifecycle CO2 emissions compared to traditional jet fuel. Despite its promise, scaling SAF production remains a challenge. Europe has positioned itself as a global leader in addressing these challenges, leveraging innovative financial tools, regulatory frameworks, and international collaboration to drive SAF adoption.
Policy at the core: ReFuelEU
Europe’s SAF progress is grounded in strong regulatory measures. The ReFuelEU Aviation Initiative, effective January 2025, mandates airlines to blend 2% SAF into their fuel supply, a target set to rise to 6% by 2030 and an ambitious 70% by 2050. These mandates create predictable demand for SAF, encouraging private investment and ensuring the sector aligns with Europe’s broader Fit for 55 decarbonization goals.
Supporting these regulations is the European Union Innovation Fund, one of the largest global clean energy funding programs. Backed by the EU’s Emissions Trading System (ETS), this fund channels billions of euros into SAF infrastructure, including advanced technologies like power-to-liquid plants and waste-to-fuel refineries. Notable examples include French and German SAF facilities converting agricultural residues into jet fuel, showcasing how public investment catalyzes innovation.
Complementing this regulatory push are monitoring systems for non-CO2 aircraft emissions, ensuring a holistic approach to aviation decarbonization. While beneficial, the regulatory complexity and cost implications highlight the need for accessible financing solutions for airlines and SAF producers alike.
Financing the aviation transition
Europe has pioneered the use of green bonds and carbon markets to support SAF development. Green bonds, structured to finance environmentally sustainable projects, provide a crucial funding stream for SAF infrastructure. Under the EU Green Bond Framework, billions of euros are being allocated to renewable energy projects, ensuring that SAF remains a priority for institutional investors.
The role of carbon markets, particularly under ICAO’s CORSIA program (International Civil Aviation Organization), has also been significant. SAF producers earn carbon credits for emissions reductions, which airlines can purchase to meet offset requirements. These credits not only create a revenue stream for SAF developers but also enhance compliance with international emissions standards.
Major European airlines, including Lufthansa and Air France-KLM, have embraced these tools, securing long-term SAF supply agreements. However, as ICAO Secretary General Juan Carlos Salazar emphasized, achieving net-zero goals will require a dramatic increase in investment, particularly from private capital and development banks.
Challenges and opportunities for SAF financing
Despite Europe’s progress, challenges persist. The high cost of SAF production and limited feedstock availability remain significant barriers. Marie Owens Thomsen, IATA’s Senior Vice President for Sustainability, highlighted these concerns at the recent Aviation Carbon conference. She pointed out that low oil prices and fossil fuel subsidies discourage investments in SAF, while fluctuating market dynamics complicate long-term planning.
Moreover, the “patchwork” of regional SAF regulations across Europe adds complexity for airlines operating internationally. ICAO’s global frameworks, such as CORSIA, aim to address these discrepancies by standardizing sustainability criteria and emissions reporting, ensuring a level playing field for all stakeholders. So, how to further finance aviation’s sustainable future today?
ICAO’s Role
The ICAO is a critical partner in Europe’s SAF journey. Through its Finvest Hub, ICAO connects SAF projects with investors, offering matchmaking services and financial tools to streamline project funding.
In collaboration with institutions like the International Renewable Energy Agency (IRENA), ICAO has advanced SAF feasibility studies, business cases, and certification processes. Its ACT-SAF program has supported over 20 SAF feasibility studies, enabling European states to align national policies with global sustainability standards. These initiatives highlight ICAO’s commitment to building a harmonized framework for SAF adoption worldwide.
Collaboration as the catalyst
Europe’s SAF advancements underscore the importance of collaboration. Public-private partnerships (PPPs) have emerged as a cornerstone of Europe’s strategy, combining government funding with private sector expertise to de-risk investments and accelerate projects. Companies like Neste and TotalEnergies are partnering with EU governments to build refineries that align with both environmental and economic objectives.
The region’s emphasis on technological innovation is another key driver of progress. Investments in cutting-edge SAF production methods, such as power-to-liquid technology, position Europe as a global leader in sustainable aviation. By setting ambitious targets and fostering collaboration, Europe is creating a model for other regions to emulate.
How to finance aviation’s sustainable future today?
Europe’s proactive approach to SAF development highlights the critical role of financing, policy, and collaboration in decarbonizing aviation. Through regulatory mandates, innovative financial tools like green bonds, and support from ICAO’s global frameworks, Europe is charting a path toward a more sustainable future for air travel.
However, significant challenges remain, including high production costs, limited feedstock supply, and the need for greater global alignment in SAF standards. Addressing these issues will require sustained investment, enhanced international cooperation, and a focus on technological innovation.
As ICAO Secretary General Salazar aptly stated, “Financing will be paramount for achieving our collective goals for a net-zero future.” Europe’s leadership in SAF initiatives demonstrates that with determination, creativity, and collaboration, the aviation sector can rise to the challenge of climate change and soar into a cleaner, greener future.
