The Financial Conduct Authority (FCA) has launched Consultation Paper CP25/34: ESG ratings: proposed approach to regulation, marking a pivotal moment in the UK’s regulatory oversight of Environmental, Social and Governance (ESG) data and ratings. Following recent legislation from HM Treasury, ESG ratings now fall within the UK’s regulatory perimeter. This reflects the government’s commitment to improving transparency, credibility and trust in sustainable finance.
The Consultation outlines proposed rules and guidance to establish a proportionate and robust regulatory framework for ESG rating providers, aiming to support well-informed investment decisions while upholding market integrity.
Insights from the UK ESG Ratings Market
To support its proposed framework, the FCA carried out a comprehensive survey involving 111 ESG rating users and 26 ESG rating providers from across the financial services sector. Insights from the research note, Understanding the UK ESG ratings market: Findings from our surveys, highlighted key trends, challenges and opportunities shaping the UK ESG ratings landscape:
- Methodology inconsistencies: ESG ratings for the same companies often vary significantly between providers, reflecting differences in weighting, metrics and data sources. This can create challenges for investors relying on consistent ESG data.
- Transparency gaps: Users reported difficulty in understanding the methodology behind ESG scores, limiting their ability to make fully informed decisions.
- Reliance on ESG ratings: Many firms integrate ESG scores into investment strategies, risk assessments and regulatory reporting, underscoring the importance of accurate and reliable ratings.
- Immature market practices: While the ESG ratings market is growing rapidly, the FCA’s findings highlighted the need for standardised practices, clearer disclosure and robust governance.
These insights shaped the FCA’s Consultation, designed to create a proportionate regulatory framework that supports both innovation and investor protection.
Alignment with Broader ESG Regulatory Frameworks
The FCA’s proposals are part of a wider international ESG regulatory landscape, including:
- Corporate Sustainability Reporting Directive (CSRD): Strengthens sustainability reporting obligations for large companies across the EU, ensuring standardised and comparable ESG disclosures.
- Corporate Sustainability Due Diligence Directive (CSDDD): Focuses on responsible corporate behaviour across supply chains, requiring companies to identify, prevent and mitigate adverse impacts on human rights and the environment.
The FCA’s approach aligns ESG ratings regulation with these frameworks, ensuring that UK firms can integrate ESG considerations consistently across reporting, investment and risk management activities.
Why ESG Ratings Regulation Matters
Reliable ESG ratings are increasingly vital to investors, firms and regulators. Transparent and methodologically sound ratings enable stakeholders to make decisions that align with sustainability objectives, manage long-term risks, including climate and social impact, and meet expanding regulatory expectations.
The FCA’s CP25/34 consultation proposes that ESG rating providers:
- Publish detailed methodologies to enhance user understanding.
- Introduce governance frameworks to mitigate conflicts of interest.
- Disclose data sources and assumptions to support comparability and credibility.
Collectively, these proposals aim to increase market confidence, reduce reputational risk and advance the UK’s sustainable finance agenda.
