The regulatory requirement operators cannot afford to misread 

The European Union’s Renewable Energy Directive, now in its third iteration (RED III), sets the compliance framework that determines whether a renewable fuel can be counted toward the EU target and used for regulated renewable claims. For operators producing or trading sustainable aviation fuel, biodiesel, biomethane, renewable hydrogen or recycled carbon fuels, RED III is not a voluntary aspiration. It is the regulatory gate through which market access is granted or denied. Operators who clear it build supply chain resilience, reduce risk and shape long-term value creation. 

EU RED III strengthens the requirements introduced by its predecessor (RED II) across three dimensions: environmental integrity criteria, greenhouse gas (GHG) emission thresholds and supply chain traceability. Operators who fall short on any one of these dimensions risk losing eligibility under RED, invalidating renewable claims and access to mandate-driven markets. 

EU RED III biofuels compliance certification through an approved voluntary scheme is the mechanism by which operators demonstrate conformity. RSB is one of a limited number of biofuel certification scheme providers recognised by the European Commission for this purpose.

What EU RED III requires: the three compliance pillars  

.

EU RED III structures its requirements around three interlocking obligations that every certified operator must meet. 

Environmental and social criteria. Feedstocks must meet land use restrictions, biodiversity protections, and carbon stock preservation rules. Operators must demonstrate that raw materials are not sourced from land with high biodiversity value or high carbon stock, including rules on high-ILUC-risk feedstocks and land-use protections. Social safeguards, including labour rights and land rights protections, apply across the supply chain. 

GHG emission reduction thresholds. Each fuel pathway must achieve a minimum GHG emission reduction compared to the fossil fuel comparator. The exact threshold depends on the fuel type and the production installation’s start date. Calculating lifecycle emissions requires robust methodology covering feedstock cultivation, processing, transport, and end use. Errors in GHG calculation are one of the most common compliance failures. 

Chain of custody and traceability. Operators must demonstrate an unbroken chain of custody from feedstock origin to final product. RED III accepts mass balance as the primary chain of custody model for physical supply chains. Each transfer point in the supply chain must be documented, audited, and verifiable.

Where RSB’s EU RED certification fits  

.

RSB operates one of the voluntary schemes recognised by the European Commission to certify operators against EU RED biofuels requirements. The RSB EU RED certification scheme covers biofuels, bioliquids, and biomass fuels, and provides a pathway for operators producing renewable fuels of non-biological origin (RFNBOs) and recycled carbon fuels (RCFs), and can support operators working with RFNBOs and recycled carbon fuels, subject to the applicable EU rules and pathway-specific requirements. 

The RSB normative framework translates RED III’s regulatory requirements into auditable, operational standards. It provides operators with a structured RSB certification process: from initial self-assessment and documentation preparation, through third-party audit by an accredited certification body, to certificate issuance and ongoing compliance monitoring. 

What distinguishes RSB’s approach is the breadth of its environmental and social framework. While RED III sets the compliance floor, RSB’s Principles and Criteria address twelve dimensions of responsible production, covering water, soil, air quality, food security, land rights, and rural and social development alongside the GHG and feedstock criteria that the directive mandates. Operators certified under RSB’s EU RED scheme meet the regulatory minimum and, through RSB’s broader framework, demonstrate credibility beyond compliance, strengthening risk management across environmental and social exposure points and supporting the operational performance that sustained market access requires.

Who needs to understand EU RED certification   

.

The compliance obligation falls directly on operators: producers, processors, traders, and blenders of renewable fuels entering the EU market. But understanding what EU RED requires extends beyond the operator’s own compliance team. 

Certification bodies and auditors need operational fluency in the RSB EU RED normative framework to conduct accurate, consistent assessments. Policy professionals and regulators engage with the scheme to understand how voluntary certification translates regulatory intent into verifiable outcomes. Procurement and trading teams at fuel buyers, airlines, and shipping operators need to interpret certification documentation to make credible sourcing claims.

In practice: aviation and beyond 

.

The aviation sector provides the clearest illustration of EU RED certification impact. Under ReFuelEU Aviation, EU airports must progressively increase the share of sustainable aviation fuel in their fuel supply from 2025. SAF producers and suppliers need EU RED certification to demonstrate that their product meets the directive’s environmental and GHG criteria. RSB currently holds 75 active certificates across seven schemes, with 37 new applications received in 2025 alone, including operators such as Repsol, Glencore, Montana Renewables, and Norden. 

The same certification logic applies across renewable fuel pathways: road transport biofuels, biomethane, renewable hydrogen, and recycled carbon fuels all fall within RED III’s scope. Operators in each of these pathways face identical compliance obligations around feedstock provenance, GHG performance, and traceability.

Build operational understanding before the audit  

.

RSB Academy has developed a dedicated self-paced e-learning course on RSB EU RED certification. The course covers the full scope of the RSB certification framework in approximately 1.5 hours: from the directive’s requirements and the RSB normative system, through GHG calculation and co-processing rules, to RFNBO criteria, chain of custody obligations, and audit and oversight procedures. 

The course is designed for operators preparing for certification, auditors assessing against the EU RED scheme, and compliance professionals responsible for maintaining the ongoing conformity that underpins operational resilience and long-term value creation.  

Enrolment opens on 7 May. Find out more about other RSB Academy courses.
