The FCA's Sustainability Disclosure Requirements (SDR) regime is the UK's flagship ESG regime, set to apply from May 2024 onwards. The SDR is primarily a product labelling regime which is accompanied by entity-level disclosure requirements, new anti-greenwashing guidance and ESG marketing requirements. This implementation guide provides a practical overview of the regime and key points for firms to consider when launching an SDR labelled fund and completing entity-level disclosures. Split into six briefing papers, our implementation guide covers: Guide A Introduction, Scope and Application An introduction to the SDR, including the scope of the regime and its application to specific products. Guide B The FCA's Anti-Greenwashing Rule A detailed review of the new anti-greenwashing rule, including practical issues that firms should bear in mind.
