Deep Dive

HKMA Deputy Chief Executive Darryl Chan said Hong Kong is expanding sustainable finance access for SMEs through a Phase 2B Hong Kong Taxonomy consultation, a broader green debt grant scheme, and a free greenhouse gas emissions calculator. The speech is not binding, but it signals supervisory priorities. Compliance teams should watch the taxonomy consultation, which will shape how transition and adaptation activities are classified and disclosed.

The most actionable item is the public consultation on Phase 2B of the Hong Kong Taxonomy, which the speech says opened "this Monday" (the week of the 11 September 2026 speech). Phase 2B expands coverage to more transition activities and adaptation measures, including hard-to-abate sectors such as iron and steel and enabling technologies such as battery storage and sustainable fuels. It is intended as a reference point for corporates benchmarking their efforts and engaging lenders and investors. Once finalized, it is likely to influence product labeling, internal green or transition classification frameworks, and client conversations. The speech gives no consultation deadline, so teams should confirm it on the HKMA website.

Two other measures matter. First, the grant scheme subsidizing green and sustainable debt issuance was refined earlier this year to cover advisory costs for developing sustainable finance frameworks and transition plans. The HKMA stressed that it is still "holding our line against greenwashing," so heightened scrutiny of labeling and claims should be expected. Second, a steering group of Hong Kong financial regulators has developed a free online emissions calculator that uses energy and water bills, and it is adding Southeast Asian emission factors. Banks may see SME clients and supply chain counterparties using it, which could affect Scope 3 and financed-emissions data quality, though the speech does not say the tool is mandated or validated for regulatory reporting.

Recommended actions: (1) Assess Phase 2B and prepare a consultation response where relevant, especially for exposure to hard-to-abate sectors. (2) Review how internal green and transition classifications would map to the taxonomy. (3) Evaluate whether the calculator could support SME data collection, with appropriate data-quality caveats. (4) Reinforce anti-greenwashing controls in sustainable debt issuance, advisory, and marketing. (5) Consider whether SME clients' transition and physical risk exposure is adequately captured in climate risk and credit frameworks. The speech notes that SMEs are especially vulnerable, lacking balance-sheet reserves, and that existing frameworks were designed for large listed corporates.

Overall impact is low for immediate compliance burden but moderate for strategic planning. Key risks are misalignment with an evolving taxonomy, greenwashing exposure, and weak SME climate data. The speech cites ADB data that SMEs account for roughly two-thirds of employment and nearly 40% of economic output in Asia, which underscores why SME climate risk is a growing portfolio concern.
