How to Prepare an ESG Report: A Step-by-Step Guide to ESG Reporting

How to Prepare an ESG Report: A Step-by-Step Guide to ESG Reporting is a foundational regulatory guidance document published by Hong Kong Exchanges and Clearing Limited (HKEX) to assist listed issuers and corporate governance practitioners in fulfilling environmental, social, and governance (ESG) disclosure requirements. Designed as a practical implementation manual for HKEX's ESG Reporting Guide (Appendix C2 / formerly Appendix 27 of the Main Board Listing Rules), the document walks practitioners through a structured step-by-step framework for corporate sustainability disclosure. It covers key stages including board-level oversight, defining reporting boundaries, conducting materiality assessments, engaging internal and external stakeholders, and applying core reporting principles (Materiality, Quantitative, Balance, and Consistency). Additionally, the guide provides clear methodologies for setting key performance indicator (KPI) targets, collecting reliable environmental and social data, and integrating climate-related risks and opportunities (aligned with TCFD recommendations). Serving as an essential open-access practical guide, this document is an indispensable reference for undergraduate and postgraduate students, academics, corporate sustainability managers, social auditors, and finance professionals studying ESG reporting, sustainable finance, corporate governance, and regulatory compliance in Hong Kong.
