This document discusses the preparedness of Indian public companies for business sustainability disclosure and reporting based on environmental, social and governance factors. It provides context on the Securities and Exchange Board of India's recent mandate requiring the top 100 companies to report on ESG initiatives using the National Voluntary Guidelines on Social, Environmental and Economic Responsibilities of Business. The document analyzes the current state of ESG reporting among Indian public companies based on a study of disclosure levels among Sensex companies. It finds that disclosure levels vary widely across sectors and companies but are generally low compared to international peers. Governance issues receive the highest levels of disclosure while employee and stakeholder information receives less.
