What is ISCC EU RFNBO?

For those navigating the complex landscape of green energy compliance, ISCC (International Sustainability and Carbon Certification) is a globally recognized sustainability certification system that verifies the sustainable sourcing, traceability, and greenhouse gas (GHG) performance of raw materials and products across supply chains. Governed by the non-profit ISCC Association (ISCC e.V.), the system enables organizations to demonstrate compliance with environmental, social, and traceability requirements through independent third-party certification.

The ISCC framework comprises several certification schemes, each designed to address specific regulatory or voluntary market needs:

  • ISCC EU – A certification scheme recognized by the European Commission for demonstrating compliance with the sustainability and GHG emissions requirements of the Renewable Energy Directive (RED III) for biofuels, biomass fuels, renewable fuels of non-biological origin (RFNBO), and recycled carbon fuels.
  • ISCC PLUS – A voluntary certification scheme that supports sustainability claims for bio-based, bio-circular, recycled, and renewable materials across industries such as chemicals, plastics, packaging, and consumer goods.
  • ISCC CORSIA – A certification scheme developed to verify sustainable aviation fuels (SAF) under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), enabling airlines to demonstrate compliance with the sustainability requirements established by the International Civil Aviation Organization (ICAO).

Within the ISCC EU scheme, Renewable Fuels of Non-Biological Origin (RFNBOs) represent a dedicated certification scope for fuels produced from renewable electricity rather than biomass. The ISCC EU RFNBO scheme has been developed to demonstrate compliance with the specific sustainability requirements established under the EU Renewable Energy Directive (RED III) and its delegated acts.

RFNBOs are liquid or gaseous synthetic fuels (like e-Gasoline, e-Methanol, and e-SAF) whose energy content comes from renewable sources other than biomass, such as hydro, wind, or solar power.

Governed by the EU’s Renewable Energy Directive (RED III) and its supporting Delegated Regulations, the certification acts as a strict "green ledger". To secure it, an e-Fuels producer must legally prove three core pillars via independent audits:

  • Additionality: the renewable electricity used to power the electrolyzers must come from new, unsubsidized renewable installations. This ensures that making e-Fuels doesn’t cannibalize existing clean energy needed by the local power grid.
  • Temporal and geographical correlation: the facility must prove that it synthesized the e-Fuel at the same time and in the same region where the renewable energy was generated.
  • Minimum 70% GHG reduction: the fuel must achieve at least 70% greenhouse gas emissions saving over its entire lifecycle compared to a strict fossil fuel baseline (using the EU methodology of 94 grams of CO2 equivalent per megajoule).
  • Traceability (mass balance): every molecule of hydrogen, carbon dioxide CO2 and finished fuel must be tracked via an audited chain of custody from inception to export.

As renewable hydrogen and e-fuels become central to the decarbonization of sectors such as aviation, maritime transport, and heavy industry, the ISCC EU RFNBO scheme provides a recognized certification pathway that enables producers, traders, and downstream users to demonstrate compliance with European regulatory requirements while providing assurance to regulators, investors, and customers regarding the sustainability and integrity of RFNBO supply chains.

Why is the ISCC EU RFNBO framework important for the market?

Europe has implemented binding laws requiring industries and transport sectors to adopt synthetic fuels. For example, under RED III, at least 42% of hydrogen used in European industry must be an RFNBO by 2030 (scaling to 60% by 2035). Without the relevant certification, a fuel will not count toward these quotas or be marketed toward regulated renewable-fuel obligations in Europe.

Additionally, financial institutions and green infrastructure investors require rigorous verification before backing e-Fuels projects. The certification provides independently verified compliance evidence, helping reduce regulatory, sustainability, and traceability risks for capital-intensive investments.

Every batch of certified fuel delivered from supplier to a buyer comes with an official Proof of Sustainability (PoS) document. This document is recorded in the official Union Database (UDB). It provides corporate buyers with mathematically bulletproof, third-party audited data that can be handed straight to environmental auditors and regulators. Under the Greenhouse Gas (GHG) Protocol and the Science Based Targets initiative (SBTi), companies are heavily restricted from using cheap, unverified carbon offsets to hit climate goals. Because RFNBO fuels physically replace fossil molecules within the value chain, they count as a direct mitigation measure:

  • For the transporter (e.g., shipping lines/airlines): It directly slashes their Scope 1 direct operational emissions.
  • For the corporate client (e.g., retailers shipping goods): It directly drops their Scope 3 (Category 4/9) value-chain logistics emissions.

RFNBO certified: How HIF Haru Oni proves e-Fuel viability

With two consecutive years of audited RFNBO compliance, HIF Haru Oni remains the living proof that a closed-loop, renewable energy-powered e-Fuels economy is technically viable, commercially scalable, and fully auditable.

It is the first facility outside the European Union to receive the official ISCC EU RFNBO certification, and the first worldwide to achieve it for commercial e-Gasoline production. Validated by the German-based ISCC framework approved by the European Commission, this certificate covers our entire production pathway, from capturing carbon to synthesizing green hydrogen, e-Methanol, e-Gasoline, and e-LG.

Furthermore, this is not a one-time achievement. By successfully maintaining this strict standard for the 2025/2026 fiscal cycle, HIF Global has proven that continuous, audited compliance is an established operational reality.

For fuel buyers, HIF Haru Oni serves as the operational foundation for HIF Global’s expanding portfolio of commercial-scale facilities under development worldwide. As international quotas tighten, off-takers and logistics enterprises can partner with HIF Global with greater confidence, knowing our synthetic molecules meet the highest legal and environmental standards on the planet.
