Compliance controls, audit, and evidence briefings

From 31 May 2024 the UK Financial Conduct Authority’s anti-greenwashing rule (ESG Sourcebook 4.3.1R) applies to all FCA-authorized firms. Sustainability references in marketing, product documentation, or financial promotions must be accurate, substantiated, and presented proportionately.

Compliance checklist

  • Evidence-based claims. Substantiate environmental and social statements with data, methodologies, and limitations before publication.
  • Governance. Embed review and approval processes for sustainability claims across marketing, product, and investor communications.
  • Ongoing monitoring. Reassess claims when products, benchmarks, or ESG strategies change to maintain accuracy.

Where to start

  • Training. Educate marketing, product, and client-facing teams on the FCA’s four fairness outcomes: correct, clear, complete, and contextual.
  • Inventory. Audit existing communications, website content, factsheets, and ESG reports to remediate unsubstantiated claims.
  • Documentation. Maintain records linking sustainability claims to underlying evidence and approvals.

This brief helps firms operationalize the anti-greenwashing rule with claim inventories, evidencing frameworks, and governance workflows.

Anti-Greenwashing Compliance

FCA anti-greenwashing rule requires sustainability claims to be fair, clear, and not misleading.

  • Claims review: Audit marketing materials and product documentation for sustainability claims compliance.
  • Evidence standards: Document substantiation for environmental and social claims in financial promotions.
  • Approval processes: Update compliance sign-off procedures for sustainability-related communications.

Rule Overview

The UK Financial Conduct Authority's anti-greenwashing rule took effect on May 31, 2024, requiring that sustainability-related claims made by FCA-authorized firms be fair, clear, and not misleading. The rule applies across all FCA-authorized firms, not limited to those offering specifically sustainability-focused products or services.

The rule addresses growing concerns about misleading sustainability claims that may influence consumer decision-making without adequate substantiation. Greenwashing undermines consumer trust and impedes the transition to a sustainable economy by misdirecting capital flows.

Scope and Application

The anti-greenwashing rule applies to all sustainability-related claims made by FCA-authorized firms, regardless of the product or service type. Claims may relate to environmental, social, or governance characteristics, including statements about sustainability strategies, commitments, or achievements.

The rule covers claims made across all communication channels including marketing materials, product documentation, websites, social media, and verbal communications. Both explicit claims and implied representations fall within scope, requiring firms to consider the overall impression created by their communications.

Key Requirements

Sustainability-related claims must be factually accurate and capable of substantiation. Firms must hold evidence supporting claims at the time they are made, with documentation sufficient to show compliance if challenged. Vague or aspirational claims without clear basis may violate the rule even if not explicitly false.

Claims must be presented in a fair and balanced manner, avoiding selective disclosure that creates misleading impressions. Firms should not overstate positive attributes while omitting relevant limitations or risks. Context and qualifications should accompany claims where necessary to ensure accurate understanding.

Compliance Framework

Firms should establish governance arrangements for reviewing and approving sustainability-related claims before publication. Review processes should involve personnel with appropriate expertise to assess claim accuracy and substantiation. Documentation of review and approval supports compliance demonstration.

Training programs should ensure personnel making sustainability-related claims understand rule requirements and firm policies. Marketing, communications, and product teams require particular attention given their role in developing and disseminating sustainability-related content.

Evidence and Substantiation

Firms must maintain evidence supporting sustainability-related claims, including data, methodologies, and third-party assessments where relevant. Evidence should be proportionate to the nature and prominence of claims. More prominent or useful claims require correspondingly strong substantiation.

Evidence retention policies should ensure documentation remains available for the expected life of claims and potential regulatory inquiry periods. Regular review of continuing claims validates that underlying evidence remains current and accurate.

FCA Guidance

The FCA published guidance alongside the rule, providing examples of good and poor practice in sustainability-related communications. Firms should review guidance to understand FCA expectations and calibrate their compliance approaches as needed. Guidance examples help illustrate application of fair, clear, and not misleading standards to sustainability claims.

Integration with SDR

The anti-greenwashing rule operates alongside the FCA's Sustainability Disclosure Requirements (SDR), which establish specific labelling requirements for sustainable investment products. Firms marketing products under SDR labels must comply with both the labelling regime and the broader anti-greenwashing rule.

Non-labeled products making sustainability-related claims remain subject to the anti-greenwashing rule. Firms should ensure consistency between SDR compliance activities and broader sustainability communication practices.

Enforcement Approach

The FCA has showed supervisory focus on sustainability-related communications as part of its consumer protection priorities. Enforcement may include requiring firms to withdraw or amend misleading claims, public censure, and financial penalties for serious violations. Early compliance investment reduces enforcement exposure.

Final assessment

The FCA's anti-greenwashing rule establishes clear expectations for sustainability-related communications by authorized firms. Investment in strong governance, substantiation practices, and staff training supports compliance while building consumer trust in sustainability claims across UK financial services.

Substantiation Requirements

The FCA anti-greenwashing rule requires firms to ensure sustainability-related claims are consistent with products' actual sustainability profile. Marketing materials must be fair, clear, and not misleading, with claims supported by robust evidence. Organizations must maintain documentation demonstrating how sustainability claims align with investment processes and portfolio characteristics.

Ongoing monitoring ensures continued accuracy of sustainability representations as portfolios evolve. Material changes affecting sustainability positioning require updated disclosures and potentially revised marketing materials.

Cross-Border Coordination

UK anti-greenwashing requirements interact with EU sustainable finance regulations including SFDR and EU Taxonomy. Organizations distributing products across jurisdictions must coordinate disclosure approaches while addressing regime-specific requirements. Divergence between UK and EU frameworks creates complexity for firms maintaining cross-border distribution relationships.
