• RSB ICAO CORSIA certification places EcoCeres’ SAF among the most rigorously verified fuels globally, meeting strict climate, social, and biodiversity criteria
• Certification supports airlines facing CORSIA compliance and emerging SAF mandates, reinforcing confidence in emissions claims and lifecycle reductions
• EcoCeres has raised approximately $800 million since 2021, underlining investor backing for scaled waste-based aviation fuel production

Hong Kong based renewable fuels producer EcoCeres has secured certification under the RSB ICAO CORSIA scheme for Sustainable Aviation Fuel, a benchmark widely regarded as the most stringent global standard for verifying SAF sustainability claims. The certification aligns with the International Civil Aviation Organization’s Carbon Offsetting and Reduction Scheme for International Aviation and adds a layer of scrutiny that goes beyond basic emissions accounting, extending into biodiversity protection, labour safeguards, and feedstock traceability.

For airlines facing tightening scrutiny over decarbonization strategies, the distinction matters. CORSIA compliance is becoming a baseline expectation for international aviation, while regional SAF blending mandates are accelerating across Europe, Asia, and parts of the Americas. In that context, certification credibility has become as important as fuel availability.

A High-Bar Certification in a Crowded SAF Market

The RSB ICAO CORSIA framework, developed by the Roundtable on Sustainable Biomaterials, is widely recognised as a best-in-class verification system. It requires significant lifecycle greenhouse gas reductions compared with conventional jet fuel, strict protection of high-carbon and high-biodiversity areas, and robust social safeguards for workers and local communities. Independent traceability requirements cover feedstock sourcing through to final fuel production.

Civil society organisations including the World Wide Fund for Nature and the International Union for Conservation of Nature have publicly endorsed the RSB approach, lending it unusual legitimacy in a sector often criticised for weak sustainability claims.

EcoCeres’ certification confirms that its SAF meets these criteria, positioning the company among a smaller group of producers able to offer independently verified fuels under the most demanding global standards.

Executive Perspective and Market Signal

“Receiving RSB ICAO CORSIA certification is a major milestone for EcoCeres and a strong endorsement of our commitment to producing SAF that delivers measurable climate benefits and advances the circular economy,” said Matti Lievonen, CEO of EcoCeres. “This recognition not only validates the robustness of our feedstock sourcing and production processes but also gives our airline partners confidence that our fuels meet the highest international standards for sustainability and emissions performance.”

For airline customers, that confidence increasingly has regulatory and reputational value. CORSIA obligations require credible verification of emissions reductions, while investors and regulators are paying closer attention to lifecycle accounting and social impacts across supply chains.

Finance, Scale, and Strategic Positioning

The certification also strengthens EcoCeres’ commercial positioning as SAF demand accelerates. The company focuses on waste-based feedstocks combined with advanced production technologies, a model designed to avoid competition with food systems and reduce land-use risks.

Since 2021, EcoCeres has raised approximately $800 million, reflecting growing investor appetite for scalable, compliance-ready low-carbon fuel platforms. That capital has supported capacity expansion and international market development, at a time when airlines are seeking long-term SAF supply agreements to manage both price risk and regulatory exposure.

With independent verification under RSB ICAO CORSIA, EcoCeres is better positioned to partner with airlines and fuel suppliers operating across multiple jurisdictions, where standards and enforcement regimes vary but scrutiny is converging upward.

Implications for Aviation Decarbonization

The certification arrives as aviation faces mounting pressure to reconcile growth with climate commitments. SAF remains the most viable near- to medium term decarbonization lever for long-haul flight, yet concerns over feedstock sustainability and exaggerated emissions claims have slowed adoption.

By meeting one of the highest global benchmarks, EcoCeres contributes to narrowing that credibility gap. The company says the certification complements its existing sustainability credentials and reflects its broader mission to convert waste into low-carbon energy solutions at scale.

As governments, financiers, and airlines push toward net-zero pathways, independently verified SAF is becoming a prerequisite rather than a differentiator. EcoCeres’ RSB ICAO CORSIA certification signals how producers will be judged in the next phase of aviation decarbonization: not only on volume and cost, but on governance, transparency, and verifiable climate impact.
