How to use this guide
This page explains a proportionate management approach for Hong Kong organisations. It is general information, not a substitute for legal, engineering, labour or other specialist advice where those disciplines are required.
When this topic matters
Supply-chain work becomes important when material emissions, labour risks, product quality, business continuity or customer requirements sit outside the reporting entity’s direct operations. It is also relevant when procurement teams receive inconsistent ESG questionnaires from customers or need evidence for tenders and investor due diligence.
What HKEX and stakeholders look for
The HKEX ESG Reporting Code includes supply-chain management within its Social subject area. It asks issuers to describe policies for managing environmental and social risks in the supply chain and practices used to identify and monitor those risks. The practical implication is that a supplier code alone is not enough: the company should be able to show how suppliers are prioritised, assessed, approved, monitored and escalated.
Hong Kong reference point
The HKSAR Government’s green procurement programme provides environmental specifications for 183 products and services across 24 categories. These specifications are not automatically private-sector requirements, but they offer useful local reference criteria for procurement teams developing their own minimum and desirable requirements.
Segment suppliers by risk, not only spend
A workable supplier-risk model combines commercial importance with the likelihood and severity of ESG impacts. Useful factors may include country and site location, sector, product or service, labour intensity, environmental footprint, substitutability, data access and previous incidents.
| Tier | Typical profile | Proportionate response |
|---|---|---|
| Priority | High spend or critical supply with material environmental, labour, quality or continuity risk. | Detailed assessment, contract clauses, evidence review, improvement plan and periodic monitoring. |
| Focused | Moderate risk or material data relevance, including major Scope 3 contributors. | Targeted questionnaire, document checks, training and selected KPI requests. |
| Standard | Low inherent risk and limited business criticality. | Supplier code, onboarding declarations and exception-based review. |
Build ESG into the purchasing cycle
- Define mandatory and desirable ESG criteria before tendering.
- Include evidence requirements and avoid unsupported self-declarations.
- Score relevant environmental and social factors alongside price, quality and delivery.
- Use contract clauses for data, incidents, audit rights and corrective action.
- Assign procurement owners for exceptions and approvals.
- Review whether the specification creates unintended barriers for smaller suppliers.
Criteria should reflect the category. Energy performance may matter for equipment; recycled content and packaging for products; labour practices for labour-intensive services; and emissions data for logistics and manufacturing.
Engage suppliers and improve value-chain data
Supplier engagement should explain why information is needed, define the calculation period and boundary, provide a consistent template and distinguish primary data from estimates. Start with the suppliers and categories most likely to change the decision or reported result rather than asking every supplier for the same information.
Practical sequence
Screen first, request data second, validate a sample third, and then design improvement actions. Collecting more fields does not compensate for unclear boundaries or no management response.
Create escalation and evidence
Define what happens when a supplier does not respond, provides unreliable data, breaches a requirement or cannot meet an improvement deadline. Retain assessment records, approvals, supporting documents, changes in risk rating and the rationale for continuing, suspending or exiting the relationship.

Questions to ask an adviser
- How will you prioritise suppliers without creating an excessive questionnaire exercise?
- How will the work connect to procurement approval and contract management?
- Which evidence will be reviewed and how will limitations be recorded?
- How will smaller suppliers be supported rather than simply excluded?
- How will supplier information connect to Scope 3 and external reporting?
