ESG reporting required as a listing rule Yes

Issuers must publish their ESG reports on an annual basis and regarding the same period covered in their annual reports. Reporting requirements can be found in the related Main Board Listing Rules (here) and the ESG Reporting Guide (the “Guide”), Appendix 27 to the Main Board Listing Rules (here).

With effect on 1 July 2020, the ESG Reporting Guide comprises two levels of disclosure obligations: (a) mandatory disclosure requirements; and (b) “comply or explain” provisions. Issuers must disclose the information required under the “Mandatory Disclosure Requirements”; and if the issuer does not report on any of the “comply or explain” provisions, it must provide considered reasons in its ESG report. The amendments had an emphasis in the board’s leadership role and accountability in ESG and the governance structure for ESG matters. HKEX also introduced climate change disclosure requirements and incorporated elements of the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD) into our Rules. In April 2022, the Exchange published a consultation on the enhancement of climate-related disclosures under its ESG framework. It proposes to mandate all issuers to make climate-related disclosures in their ESG reports, and introduce new climate-related disclosures aligned with the IFRS S2 Climate-related Disclosures exposure draft (as supplemented and modified by deliberations of the International Sustainability Standards Board (ISSB) up to April 2023). The consultation paper on the enhancement of climate-related disclosures under the ESG framework can be found (here).

Disclosure requirements on corporate governance issues are contained in the Corporate Governance Code, Appendix 14 to the Listing Rules (here). With effect on 1 January 2022, the Corporate Governance Code was revised to further enhance corporate governance standards among listed issuers in Hong Kong, specifically in the areas of corporate culture, director independence and diversity. The Corporate Governance Code mandates that IPO applicants must have at least one female director on board and existing listed issuers must appoint at least one female director on their boards by the end of 2024. 

Issuers are required to publish ESG reports (covering financial year commencing on or after 1 January 2022) at the same time as publication of annual reports. Consultation paper and conclusions on the amendments can be found here.

Has written guidance on ESG reporting Yes

Offers ESG related training Yes

All resources can be found on the HKEX ESG Academy, a centralised ESG educational platform launched in November 2021 to guide issuers and the broader business community in their sustainability journeys. The ESG Academy comprises several sections which houses all training and guidance materials published by the Exchange. In April 2022, the Exchange launched a new page headed “ESG in Practice” under the ESG Academy, which highlights the Exchange’s latest ESG regulatory developments, and provides examples of exemplary ESG practices amongst its issuers. 

The Exchange launched e-training courses, for directors to help them develop and refresh their knowledge and skills so as to ensure that their contribution to the board remains informed and relevant. In May 2021, the ESG Academy Webinar Series was launched to deepen ESG understanding and knowledge among listed issuers and the wider business community, and facilitate the integration of ESG considerations into their decision making processes. The Director Training Programme 2017/2018 also covers the topic of ESG reporting.

HKEX representatives also gave presentations at events organised by various non-governmental organisations and professional organisations to identify the latest trends and share practical advice in relation to ESG reporting.

In 2022, HKEX provided training on Climate-related Financial Disclosures (TCFD recommendations) in collaboration with the SSE, CDP and IFC. (source)
