Environmental, Social, and Governance (ESG) ratings are assessments of ESG matters, which increasingly drive investment decisions in financial markets. As part of the Edinburgh reforms in December 2022, the Chancellor announced that the government wants to ensure improved transparency and good conduct in the ESG ratings market, and that HM Treasury will consult on a potential regulatory regime for their providers. This consultation paper sets out proposals for the scope of such a regulatory regime. The consultation opens on 30 March 2023 and will close on 30 June 2023. Responses will inform the government’s next steps. Please submit your responses to ESGRatingsConsultation@hmtreasury.gov.uk.
