Minimum Social Safeguards
The Minimum Social Safeguards (MSS) are the third test every taxonomy-aligned activity must pass — alongside Substantial Contribution TSC and DNSH. They require companies to comply with international human rights, labour, and anti-corruption standards. Many companies underestimate the documentation burden.
The Minimum Social Safeguards (MSS) are the third test every taxonomy-aligned activity must pass — alongside Substantial Contribution TSC and DNSH. Article 18 of the EU Taxonomy Regulation requires that companies conducting taxonomy-aligned activities comply with the OECD Guidelines for Multinational Enterprises and the UN Guiding Principles on Business and Human Rights (UNGPs) — including the ILO Core Labour Standards.
What the Minimum Social Safeguards require
Article 18 of the EU Taxonomy Regulation requires that companies conducting taxonomy-aligned activities comply with the OECD Guidelines for Multinational Enterprises and the UN Guiding Principles on Business and Human Rights (UNGPs) — including the ILO Core Labour Standards.
The MSS cover four areas:
Human rights due diligence: Processes to identify and address adverse human rights impacts across operations and value chain — aligned with UNGPs Pillar II (Corporate Responsibility to Respect).
Fair competition: Compliance with competition law — no cartel behaviour, no abuse of dominant position.
Tax compliance: No engagement in aggressive tax planning — paying taxes where economic activity occurs, consistent with OECD BEPS principles.
Worker rights: Respect for ILO Core Conventions — freedom of association, collective bargaining, no child labour, no forced labour, non-discrimination.
MSS assessment in practice
The Platform on Sustainable Finance (the EU Taxonomy advisory body) has published guidance on MSS assessment. The assessment is company-level — not activity-level. A company either passes MSS across its operations or it does not.
In practice, most large companies pass MSS through: their existing UNGP-aligned human rights due diligence programme; OECD Guidelines compliance (required for companies operating in OECD countries); existing anti-corruption and competition compliance programmes; and ESRS S1/S2/G1 disclosure which covers the same ground.
The documentation requirement is the main challenge: you need to be able to demonstrate to assurers that these frameworks are actively implemented — not just that policies exist. Evidence required: human rights due diligence process documentation; supply chain audit records; anti-corruption training completion data; tax transparency reporting (GRI 207).
MSS and ESRS — the overlap
ESRS disclosure provides significant evidence for MSS compliance — the two frameworks cover substantially the same ground:
ESRS S1 (Own Workforce) → ILO Core Labour Standards compliance for own employees.
ESRS S2 (Value Chain Workers) → Supply chain human rights due diligence under UNGPs.
ESRS G1 (Business Conduct) → Anti-corruption (OECD Guidelines Principle 7) and tax compliance.
For CSRD companies: your ESRS S1, S2, and G1 disclosures are the primary evidence base for MSS. Build your ESRS disclosures first, then use them to populate your MSS assessment documentation. Avoid creating parallel evidence trails — one well-documented programme supports both.
The key MSS element without a direct ESRS equivalent is fair competition / antitrust compliance. Maintain your legal compliance records and competition law training documentation separately as MSS evidence.
Frequently asked questions
Do SMEs need to comply with Minimum Social Safeguards?
MSS apply to all companies conducting taxonomy-aligned activities — regardless of size. However, the Platform on Sustainable Finance guidance acknowledges proportionality — smaller companies can demonstrate MSS through lighter-touch evidence (policy documents, supplier questionnaires) rather than the full due diligence programmes expected of large multinationals.
What happens if we fail MSS?
If a company fails MSS, none of its activities qualify as taxonomy-aligned — even if all activities meet TSC and DNSH. MSS is a gateway test. Failure to meet MSS means zero aligned revenue, CapEx, and OpEx. This is a significant incentive for large companies to maintain robust human rights and governance programmes.
How do assurers verify MSS compliance?
Assurers review: the existence and content of human rights policy and due diligence process; evidence of active implementation (audit records, grievance mechanism logs, training records); GRI 207 tax disclosure or equivalent; and competition compliance programme documentation. They are not expected to conduct independent human rights audits — they assess whether a functioning due diligence process exists.
