A Sponsor's Assessment and Disclosure of Climate Change Risk for the Listing Applicant

The regulatory spotlight on climate-related risk in Hong Kong’s listing regime has shifted from voluntary disclosure to a sponsor’s mandatory duty of care. On 1 January 2025, the Hong Kong Stock Exchange (HKEX) implemented its enhanced climate disclosure requirements under Appendix 27 of the Main Board Listing Rules, mandating that all listed issuers publish climate-related information in their Environmental, Social and Governance (ESG) reports on a “comply or explain” basis. For sponsors, this is not merely an issuer-side obligation. The SFC’s Code of Conduct for Persons Licensed by or Registered with the Securities and Futures Commission (the Code), specifically Paragraph 17.6, requires a sponsor to conduct “reasonable due diligence” to ensure that all material information in a listing application is accurate and complete. Climate change risk now sits squarely within that definition of materiality. A sponsor that fails to assess and disclose an applicant’s exposure to physical climate risk, transition risk, or stranded asset risk is exposing itself to enforcement action under the SFC’s Sponsor Regime, which carries penalties including licence suspension and fines of up to HKD 10 million per breach (SFC, Sponsor Enforcement Cases, 2024). This article sets out the specific regulatory mechanics, due diligence steps, and disclosure standards a sponsor must apply when assessing a listing applicant’s climate change risk.

The Regulatory Framework: From Voluntary to Mandatory

HKEX’s Enhanced Climate Disclosure Rules (Appendix 27)

The HKEX’s revised ESG reporting framework, effective for financial years commencing on or after 1 January 2025, requires issuers to disclose climate-related risks and opportunities in line with the International Sustainability Standards Board (ISSB) IFRS S2 Climate-related Disclosures. Appendix 27 of the Main Board Listing Rules now mandates disclosure of four core pillars: governance, strategy, risk management, and metrics and targets. For a listing applicant, this means the sponsor must ensure that the prospectus (招股書) contains a forward-looking climate risk assessment that covers at least the next 12 months from the listing date, and where practicable, a 3-5 year scenario analysis.

The HKEX’s Guidance on Climate Disclosures (HKEX, 2024) explicitly states that “an issuer should consider the impact of climate-related risks and opportunities on its business model, strategy, and financial planning.” For sponsors, this translates into a due diligence obligation to verify that the applicant has identified its material climate risks, quantified their potential financial impact, and integrated these findings into its business plan. The SFC’s Report on the Sponsor Thematic Inspection (SFC, 2023) found that 40% of sponsor due diligence files reviewed contained no assessment of environmental or climate-related risks, a deficiency the SFC described as “a significant gap in the sponsor’s duty to identify material risks.”

The Sponsor’s Duty Under Paragraph 17.6 of the SFC Code

Paragraph 17.6 of the Code requires a sponsor to “take reasonable steps to ensure that the listing document contains all material information required by the Listing Rules and the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32).” The SFC’s Guidelines on the Duties of Sponsors (SFC, 2022) further clarifies that materiality is not static: a risk that is immaterial for one sector—say, a low-emissions service provider—may be critical for another, such as a shipping company with significant Scope 1 emissions. The sponsor must therefore conduct a sector-specific materiality assessment, cross-referencing the applicant’s operations against the Task Force on Climate-related Financial Disclosures (TCFD) sectoral guidance, which the HKEX has adopted as a reference framework.

A 2024 enforcement case illustrates the consequences of failure. In SFC v. Sponsor X (SFC, 2024), the SFC fined a sponsor HKD 8 million for failing to disclose that a listing applicant’s primary manufacturing facility was located in a flood-prone area in Guangdong Province, a physical climate risk that later caused a 30% production downtime. The SFC’s decision noted that the sponsor had not reviewed the applicant’s flood risk insurance coverage, nor had it obtained a climate risk assessment from a qualified third-party consultant. The case establishes a clear precedent: a sponsor cannot rely solely on the applicant’s own representations about climate risk; independent verification is required.

Due Diligence Methodology: Identifying and Quantifying Climate Risk

Physical Risk Assessment: Location, Supply Chain, and Insurance

The first step in a sponsor’s climate due diligence is a physical risk assessment. This requires the sponsor to map the applicant’s key physical assets—factories, warehouses, data centres, and logistics hubs—against climate hazard data. The HKEX’s Climate Disclosure Guidance (2024) recommends using scenario analysis based on the Intergovernmental Panel on Climate Change (IPCC) Representative Concentration Pathways (RCPs) 4.5 and 8.5. For a Hong Kong-listed applicant with operations in the Pearl River Delta, the sponsor must assess the probability of typhoon-induced flooding, extreme heat events, and sea-level rise over the asset’s useful life.

The sponsor should obtain from the applicant the following documents: (i) property insurance policies, including flood and business interruption coverage; (ii) historical records of climate-related disruptions; and (iii) any third-party climate risk reports commissioned by the applicant. The sponsor must then verify that the insurance coverage is commensurate with the risk. For example, if the applicant’s primary factory is in a flood zone with a 1-in-50-year return period, the sponsor should confirm that the policy covers both property damage and business interruption for a period of at least 12 months. The SFC’s Sponsor Thematic Inspection Report (2023) found that 65% of sponsors did not review insurance policies for climate-related exclusions, a gap the SFC now expects sponsors to close.

Transition Risk Assessment: Regulatory, Market, and Technology Shifts

Transition risk—the risk of financial loss from the shift to a low-carbon economy—requires a different analytical lens. The sponsor must assess the applicant’s exposure to carbon pricing, emissions regulations, and technological disruption. For a Main Board applicant in the manufacturing sector, this means evaluating the applicant’s Scope 1, 2, and 3 emissions relative to industry benchmarks. The HKEX’s Climate Disclosure Guidance (2024) requires issuers to disclose their greenhouse gas (GHG) emissions in tonnes of CO2 equivalent, using the GHG Protocol Corporate Standard.

The sponsor should request the applicant’s carbon footprint data for the past three financial years, including a breakdown by scope. If the applicant’s Scope 1 emissions exceed 10,000 tonnes CO2e per year, the sponsor should assess the impact of the Hong Kong SAR’s proposed carbon tax, which the Environment and Ecology Bureau has indicated will be set at HKD 100 per tonne CO2e from 2026 (Ecology Bureau, Carbon Neutrality Roadmap, 2024). For a manufacturing applicant emitting 50,000 tonnes CO2e annually, this would represent an additional annual cost of HKD 5 million, a material figure that must be disclosed in the prospectus’s risk factors section.

The sponsor must also evaluate the applicant’s reliance on fossil fuel-based energy. If the applicant’s energy mix includes more than 30% coal-fired power, the sponsor should consider the risk of stranded assets as China accelerates its coal-to-renewables transition. The SFC’s Guidelines on Climate-related Disclosures (SFC, 2023) explicitly state that “an issuer should disclose the resilience of its strategy to climate-related scenarios, including a scenario aligned with the Paris Agreement’s 1.5°C target.” The sponsor must therefore ensure the applicant has conducted a scenario analysis that models the financial impact of a carbon price of USD 50-100 per tonne by 2030, consistent with the International Energy Agency’s Net Zero Emissions by 2050 Scenario (IEA, 2023).

Disclosure Standards: What the Prospectus Must Contain

Risk Factors Section: Climate Risk as a Material Risk

The prospectus’s risk factors section must include a dedicated climate risk disclosure. The HKEX’s Listing Decision LD143-2024 (HKEX, 2024) established that climate-related risks must be disclosed as a “material risk” if they could reasonably be expected to have a significant adverse impact on the applicant’s financial condition, operations, or reputation. The disclosure must be specific, not generic. For example, instead of stating “the applicant is exposed to climate change risks,” the prospectus should state: “the applicant’s manufacturing facility in Dongguan is located in a flood-prone area with a 1-in-50-year flood return period. A flood event could cause property damage of up to HKD 20 million and business interruption of up to 60 days, representing 15% of annual revenue.”

The sponsor must ensure that the risk factor is quantified wherever possible. The SFC’s Code of Conduct Paragraph 17.9 requires that “all material information in a listing document must be presented in a clear and balanced manner, and must not omit material facts that would make the information misleading.” A sponsor that includes a vague climate risk statement without financial quantification is at risk of breaching this provision. The SFC’s Enforcement Report 2024 noted that 30% of prospectuses reviewed contained climate risk disclosures that were “boilerplate and insufficiently tailored to the applicant’s specific circumstances,” a deficiency the SFC said it would pursue in future enforcement actions.

Business Section: Climate Strategy and Resilience

Beyond risk factors, the prospectus’s business section must describe the applicant’s climate strategy and its resilience to climate-related scenarios. The HKEX’s Guidance on Climate Disclosures (2024) recommends that issuers disclose their governance structure for climate risk, including board oversight and management’s role. For a sponsor, this means verifying that the applicant’s board has formally assigned climate risk oversight to a specific committee—typically the audit committee or a dedicated ESG committee—and that the committee meets at least quarterly to review climate-related metrics.

The sponsor should also request the applicant’s climate transition plan, if one exists. The HKEX’s Climate Disclosure Guidance (2024) states that “an issuer should disclose its climate-related targets, including any targets for reducing GHG emissions, and the progress made against those targets.” If the applicant has set a net-zero target, the sponsor must verify that the target is supported by a credible roadmap, including specific milestones for reducing Scope 1, 2, and 3 emissions. The SFC’s Guidelines on Climate-related Disclosures (SFC, 2023) caution that “an issuer should not make unsubstantiated claims about its climate performance,” and the sponsor must ensure that any forward-looking statements are based on reasonable assumptions and are clearly identified as such.

Enforcement and Penalties: The Sponsor’s Liability

SFC Enforcement Actions and Penalties

The SFC has demonstrated a willingness to pursue sponsors for climate-related due diligence failures. In SFC v. Sponsor Y (SFC, 2024), the SFC fined a sponsor HKD 6 million for failing to disclose that a listing applicant’s primary raw material supplier was located in a region subject to increasingly severe droughts, a physical climate risk that later caused a 40% increase in raw material costs. The SFC’s decision stated that the sponsor “did not conduct adequate due diligence on the applicant’s supply chain resilience to climate change, nor did it disclose the risk in the prospectus.”

The penalties for such breaches can be severe. Under the Securities and Futures Ordinance (Cap. 571), the SFC can impose a fine of up to HKD 10 million or three times the profit gained or loss avoided, whichever is higher, for each breach of the Code. For a sponsor, a single climate-related due diligence failure can result in multiple breaches—failure to identify the risk, failure to disclose it, and failure to verify the applicant’s representations—each carrying its own penalty. The SFC’s Enforcement Report 2024 noted that the average fine for sponsor misconduct in 2023-2024 was HKD 4.2 million, with climate-related cases accounting for 25% of all sponsor enforcement actions.

Practical Steps for Compliance

To mitigate liability, sponsors should implement a structured climate due diligence framework. This framework should include: (i) a sector-specific climate risk questionnaire for the applicant, covering physical and transition risks; (ii) independent verification of the applicant’s climate data by a qualified third-party consultant, such as an environmental engineering firm or a climate risk analytics provider; and (iii) a formal sign-off by the sponsor’s compliance officer on the adequacy of the climate risk disclosure in the prospectus.

The sponsor should also document its due diligence process in a climate risk memorandum, which should be included in the sponsor’s working papers. The SFC’s Guidelines on the Duties of Sponsors (2022) require that “a sponsor must maintain a complete and accurate record of all due diligence steps taken, including the sources of information and the analysis performed.” A well-documented climate risk memorandum will serve as a defence in the event of an SFC investigation, demonstrating that the sponsor took reasonable steps to identify and disclose climate-related risks.

Actionable Takeaways for Sponsors

1. Incorporate a climate risk assessment into the sponsor’s standard due diligence checklist, using the HKEX’s Climate Disclosure Guidance (2024) and the SFC’s Guidelines on Climate-related Disclosures (2023) as the baseline framework.

2. Obtain independent third-party verification of the listing applicant’s physical and transition climate risks, including scenario analysis aligned with IPCC RCP 4.5 and 8.5, and document the verification in the sponsor’s working papers.

3. Ensure the prospectus’s risk factors section includes quantified climate risk disclosures, with specific financial impact estimates based on the applicant’s location, supply chain, and emissions profile, rather than generic statements.

4. Verify that the applicant’s board has assigned formal climate risk oversight to a committee and that the committee meets at least quarterly, with minutes documenting its climate-related deliberations.

5. Conduct a post-listing review of the applicant’s climate risk disclosures within 12 months of listing to ensure ongoing compliance with Appendix 27 of the Main Board Listing Rules, and maintain a record of this review in the sponsor’s compliance file.
