Almost two years after the European Union's Sustainable Finance Disclosure Regulation came into force in March 2021, the landscape of funds classified as "light green" (Article 8) or "dark green" (Article 9) is going through some radical changes. In recent months, asset managers have been preparing to implement the SFDR Level 2's regulatory technical standards, or RTS, which came into effect in January 2023 and require managers to disclose more information on their funds' environmental, social, and governance approaches, sustainability risks, and impact in precontractual documents and periodic reports.
