EU renews RSB recognition to 2031: biomethane certification from production to grid injection

RSB is a Geneva-based nonprofit association that develops sustainability standards for fuels, biomass and materials. Its membership includes businesses, civil-society organisations and academic institutions, with governance structured to balance different stakeholder interests.^[1]

Three distinct roles underpin its EU certification system:^[2]

RSB’s wider framework contains 12 sustainability principles, encompassing emissions, biodiversity, soil and water protection, labour and human rights, food security and land rights. Its EU RED scheme applies the relevant framework alongside the regulatory requirements needed for EU renewable-fuel compliance. The requirements applicable to an operator depend on its activities and certification scope.^[3]

From biofuels initiative to broader biomaterials certification

RSB’s development predates the latest recognition by almost two decades. Biomethane was already covered under the preceding recognition framework; the October 2026 decision updates RSB’s existing recognition under EU renewable-energy legislation and extends its certification scope.

Commission Implementing Decision (EU) 2026/2316 replaces Decision (EU) 2022/607.^[4] It operates under Article 30(4) and (5) of the Renewable Energy Directive—RED—and recognises RSB as a means of demonstrating compliance with specified requirements. Fig. 02 sets the six recognised functions against the 2022 decision it replaces.

RSB must notify material changes to its scheme; the Commission then assesses whether recognition remains justified.

The 2022 decision already covered biomass-fuel sustainability, GHG information, low-ILUC certification and database accuracy. Database reporting and transmission of emissions information therefore remain continuing functions.^[5] Two updates are particularly relevant to biomethane:

The 2022 decision recognised RSB’s role in verifying database reporting for RFNBOs and recycled-carbon fuels. The 2026 decision extends that recognition to checking compliance with renewable-electricity requirements for RFNBO production and verifying greenhouse-gas savings calculations for both fuel categories.^[5]

The comparison is commercially relevant because recognised schemes do not necessarily cover the same fuels, feedstocks or supply-chain stages.

For a biomethane project, the useful question is: does the chosen scheme cover the activities and end use required by the transaction?

RSB joins ISCC EU and REDcert in offering recognised RFNBO certification, enabling RSB users to certify biomethane and synthetic-fuel activities within the same framework. For biomethane, the key distinction remains RSB’s injection-point boundary, compared with coverage through consumption under ISCC EU and REDcert. Downstream certification can be provided through another recognised scheme (section 05). Additional social and environmental criteria become relevant where buyers specify them in procurement requirements.

For grid-connected biomethane, the decision’s stated scope ends at injection. A buyer should therefore distinguish evidence supporting the injected consignment from evidence supporting its subsequent withdrawal, conversion and final use. This matters particularly where an offtake contract promises delivery to an industrial consumer or a bio-LNG supply chain.

The practical implication is to identify which certified operator and recognised scope cover each stage after injection. Using different schemes across a supply chain is possible: Article 8 of Implementing Regulation 2022/996 requires acceptance of evidence from other Commission-recognised voluntary schemes, within the scope of their recognition. The decisive issue is continuity of valid evidence across the transaction.^[6]

For contracts, that means specifying responsibility for:

The Commission’s Union Database guidance describes a specific treatment for grid-injected gases:^[7]

Sustainability and emissions records depend on valid operator certificates and identifiable Proofs of Sustainability. For a biomethane producer, the resulting control requirement is concrete:

A discrepancy can leave the producer able to demonstrate physical gas delivery while unable to substantiate the accompanying sustainability claim. Where the contract pays separately for compliant renewable attributes, that creates a direct acceptance or payment risk.

The decision recognises RSB’s role in verifying that operators report accurate transaction, sustainability and emissions data to the Union or national database.

RED Article 30(9) gives recognised certification an important legal effect: Member States cannot require additional evidence for the compliance elements already covered by the Commission’s recognition. This reduces the risk of duplicative sustainability verification across national markets. The protection is limited to those recognised elements.^[8]

The implication for biomethane sales is to separate two questions:

This distinction is particularly relevant to feedstocks. Low-Indirect Land-Use Change (ILUC) certification does not establish advanced-biofuel status, which depends on the applicable RED feedstock classification.

There is also a limit within the decision itself: Article 1(a) does not include the forest-biomass criteria in Article 29(6)–(7). Its broad recital language about feedstocks should therefore not be treated as recognition of those omitted criteria.^{[8] [4]}

The additional RFNBO coverage is relevant to developers considering renewable hydrogen combined with captured biogenic CO₂, including CO₂ from biomethane upgrading, to produce synthetic fuels.

The analytical implication is that RSB may offer a common certification framework across the biological and synthetic-fuel activities. Each pathway must still meet its own requirements. RFNBO production remains subject to the applicable renewable-electricity rules, including additionality and temporal and geographical correlation where required.^[9]

The more material constraint is carbon-credit allocation. Regulation 2023/1185, Annex A, point 10(c), permits relevant treatment of captured CO₂ from compliant biofuel or biomass-fuel production, provided that capture has not already received the specified carbon-capture-and-replacement credit under RED’s bioenergy methodology.^[10]

For a biomethane producer supplying CO₂ to an e-fuel project, this requires coordination between the two emissions accounts. The parties should establish which fuel pathway claims the benefit and ensure their calculations and commercial agreements are consistent. The same capture benefit cannot simply be assumed in both product accounts.
