The General Rules (Corporate Sustainability Reporting) and Minor and Technical Amendments Rules 2025 (the CSR Rules) introduce new sustainability reporting requirements for all Category A firms and any other authorised firm designated by the Regulatory Authority.

The guidance is divided into 7 Chapters covering the following stages in the implementation journey:
