Summary

RSB Certification is a voluntary global certification system for biomass, biofuels, biomaterials and circular economy supply chains. It is based on 12 Principles and Criteria covering social, legal, environmental and management practices for sustainable production in the bio-circular economy. RSB certification can support market access for sustainable aviation fuel, biofuels, renewable chemicals, plastics and biomaterials, including in some regulated markets. It uses chain-of-custody and claims controls and maintains public certificate information. It does not replace fuel law, environmental permits, labor law, land rights rules, food and feed rules or consumer protection law.

Details

Jurisdictions
  • Global
Mandatory for

RSB is not universally legally mandatory.

It can become practically required where:

A buyer requires RSB-certified feedstock or product.
A SAF program references RSB.
A regulated market accepts or requires RSB evidence.
A procurement process requires sustainable biomaterials certification.
A brand requires certified circular or bio-based materials.
A product claim depends on RSB certification.

Voluntary for

In most cases, RSB is voluntary and used to substantiate sustainability, traceability and responsible sourcing claims.

What’s Required

1. Certification against RSB standards

RSB certification uses standards and procedures designed for operators in biomass, biofuels, biomaterials, and circular value chains. RSB describes its process as an 8-step certification pathway for participating operators.

Organizations may need to document:

  • Feedstock type.

  • Production process.

  • Sustainability risks.

  • Chain of custody.

  • Land-use impacts.

  • GHG emissions.

  • Social safeguards.

  • Environmental management.

  • Traceability.

  • Claims and labeling.

2. Twelve Principles and Criteria

RSB’s sustainability framework is based on 12 Principles and Criteria covering social, legal, environmental, and management practices for sustainable production in the bio-circular economy.

Areas may include:

  • Legality.

  • Planning and monitoring.

  • Greenhouse gas emissions.

  • Human and labor rights.

  • Rural and social development.

  • Food security.

  • Conservation.

  • Soil, water and air.

  • Technology and waste.

  • Land rights.

  • Chain of custody.

  • Continuous improvement.

3. Chain of custody and claims

RSB includes chain-of-custody requirements and claims procedures. RSB’s certification resources include courses and guidance on Chain of Custody, book and claim, EU RED and ICAO CORSIA.

Companies may need:

  • Supplier verification.

  • Material accounting.

  • Sustainability claims controls.

  • Traceability records.

  • Batch or volume documentation.

  • Book and claim controls where applicable.

  • Certification body audit evidence.

4. Regulatory and market recognition

RSB states that its Principles and Criteria are recognized by regulators and global brands and can unlock access to regulated markets, including the EU.

This is relevant for:

  • Sustainable aviation fuel.

  • Biofuels.

  • Biomaterials.

  • Renewable chemicals.

  • Circular economy materials.

  • Regulated fuel markets.

  • Corporate sourcing claims.

5. Valid certificates and public verification

RSB maintains a public certificate database showing certified operators. It states that operators around the world have achieved RSB certification, demonstrating commitment to sustainability practices.

Important Deadlines

RSB is voluntary, so there is no universal legal deadline.

Important timing points:

  • Certification timing depends on application, public consultation where applicable, audit, corrective actions, and certification decision.

  • RSB certification can be used in specific regulated or market-based contexts, including EU RED and ICAO CORSIA-related pathways.

  • Operators should check current RSB standard versions, modules and claims rules before certification.

  • RSB publishes current certificates and certification information through its website.

Current Status

RSB Certification is active and global. RSB describes itself as a global nonprofit organization supported by more than 150 industry, civil society, academic, UN and government members.

Current status:

  • Active global certification system.

  • Covers biomass, biofuels, biomaterials and circular economy supply chains.

  • Based on 12 Principles and Criteria.

  • Relevant to SAF, biofuels, renewable chemicals, plastics and circular materials.

  • Supports chain of custody, book-and-claim, and market claims.

  • Recognized by regulators and brands in relevant markets.

Penalties for Non-Compliance

RSB does not impose statutory penalties.

Possible consequences include:

1. Certification refusal

Operators may fail certification if requirements are not met.

2. Suspension or withdrawal

Certificates may be suspended or withdrawn if non-conformities are not corrected.

3. Loss of claim rights

Companies may be unable to make RSB claims if certification scope or chain-of-custody evidence is invalid.

4. Market access consequences

Failure may affect access to buyer programs or regulated markets that accept RSB certification.

5. Greenwashing risk

Unsupported bio-based, circular, SAF or sustainable biomass claims can create reputational and legal risk.

Examples of Known Violations / Failure Modes

Typical failure modes include:

  • Claiming RSB certification without a valid certificate.

  • Applying RSB claims outside certified scope.

  • Weak chain-of-custody records.

  • Misclassifying feedstock.

  • Missing GHG data.

  • Ignoring land-use or food security impacts.

  • Treating RSB as a substitute for all fuel regulations.

  • Making SAF claims without proper pathway evidence.

  • Using book and claim incorrectly.

  • Continuing claims after certificate suspension.

  • Confusing RSB Global certification with ISCC EU or ISCC PLUS.

  • Making product claims beyond the approved claims procedure.
