Hong Kong to Phase in Sustainability Disclosure Rules by Industry

Hong Kong will phase in sustainability disclosure rules by industry, aligning fully with International Sustainability Standards Board (ISSB) requirements, Financial Services Secretary Christopher Hui announced. Publicly accountable entities must comply by 2028 under the government’s roadmap, while Hong Kong Exchanges and Clearing will consult in 2027 on mandating listed firms to report under local standards. Unlisted financial institutions will also be encouraged to adopt based on market feedback. Hui said the phased adoption will improve transparency, comparability and consistency of ESG data, enabling investors to make informed decisions and reinforcing Hong Kong’s role as one of the first jurisdictions committed to full ISSB adoption.
