ESG Regulations for Hong Kong SMEs 2025

Sustainability is no longer just a buzzword — it’s a business expectation. In Hong Kong, formal ESG reporting is legally mandatory only for companies listed on the Stock Exchange of Hong Kong (SEHK) under the Listing Rules and ESG Reporting Guide. From 1 January 2025, listed companies will begin phasing in enhanced climate‑related disclosures aligned with the IFRS S2 Climate‑related Disclosures standard, with guidance referencing IFRS S1.

While non‑listed SMEs are not legally required to publish ESG reports, many face strong commercial pressure to follow similar practices — especially when working with listed companies, regulated financial institutions, or multinational supply chains.

What is ESG and why does it matter?

ESG refers to:

• Environmental — energy use, emissions, waste, resource efficiency.
• Social — employee welfare, diversity, community engagement.
• Governance — board structure, transparency, anti‑corruption.

Globally, ESG performance is linked to investor confidence, brand trust, and risk management. In Hong Kong, it is increasingly a market access and financing consideration.

Are SMEs legally required to report on ESG?

Non‑listed SMEs currently have no statutory ESG reporting obligation. However:

• SMEs in regulated sectors — such as SFC‑licensed asset management, banking, or insurance — may be subject to ESG‑related compliance requirements under sector‑specific rules (e.g., HKMA’s Green and Sustainable Banking guidelines, SFC’s climate‑related risk management requirements).
• Many SMEs must demonstrate ESG readiness to meet procurement standards, qualify for sustainability‑linked financing, or attract private investment.

Key ESG Frameworks in Hong Kong

• HKEX ESG Reporting Guide — updated 2020; April 2024 amendments introduce IFRS S2‑aligned climate disclosure requirements for listed companies from 1 January 2025.
• Task Force on Climate‑related Financial Disclosures (TCFD) — forms part of the basis for Hong Kong’s climate disclosure regime.
• HKMA Green and Sustainable Banking Guidelines — applicable to authorised institutions.
• SFC Fund Manager Code of Conduct amendments — climate‑related risk management and disclosure for fund managers.
• ISSB Standards (IFRS S1 & S2) — global baseline for sustainability disclosures.

Risks of Ignoring ESG

• Supply chain exclusion by ESG‑conscious partners.
• Difficulty accessing sustainability‑linked financing.
• Reputational harm in markets where ESG is valued.
• Higher compliance costs if ESG reporting becomes mandatory in future.
