UK-listed companies and financial sector participants are likely entering a new phase of securities litigation exposure. Three developments are converging:
Environmental, social and governance (ESG) disclosures are becoming structured, evidence-based datasets rather than narrative positioning.
UK sustainability disclosure architecture is tightening through overlapping regimes: Financial Conduct Authority (FCA) anti-greenwashing and Sustainability Disclosure Requirements (SDR) (within their perimeter), listed-company disclosure reform, and UK Sustainability Reporting Standards (UK SRS S1 and S2), now published for voluntary use.
Litigation under sections 90 and 90A of the Financial Services and Markets Act 2000 (FSMA) (and since 19 January 2026 regulation 30 of the Public Offers and Admissions to Trading Regulations 2024 (POATR)) is evolving, particularly around investor reliance, case management and collective action mechanics.
Together, these trends increase the risk that ESG disclosures, especially forward-looking sustainability and transition statements, become a significant source of UK securities claims. The strategic question for boards and in-house counsel is how disclosure governance must adapt.
