Corporate governance and supply chains

Corporate governance decides how a company is directed and to whom it answers. Supply chains extend that question beyond the firm: environmental, human rights and integrity risks often arise at suppliers several tiers away, where the company has influence but not control. Due diligence is how companies identify, prevent, mitigate and account for those impacts. This page sets out how governance failure travels along value chains, how it can be read, and which decisions sit with boards, regulators and investors.

01In brief

The short answer.

Supply chain due diligence is the process by which companies identify, prevent, mitigate and account for environmental, human rights and integrity risks in their own operations and across suppliers several tiers away, where they have influence but not control. A supplier audit is one input, not the whole process.

04The question

Corporate governance and supply chains: how the risk develops.

Business governance and due diligence. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Risk sits where visibility ends

Most firms know their direct suppliers but not the tiers below. Forced labour, deforestation, unsafe conditions and bribery concentrate where traceability stops, and contractual distance becomes a reason for not knowing.

Mechanism

Incentives push risk downstream

Price pressure, short lead times and late order changes are set at headquarters and absorbed by suppliers. Codes of conduct then ask suppliers to meet standards that the buyer's own purchasing practices make harder to meet.

Mechanism

Audits stand in for due diligence

Announced social audits and certificates can become a substitute for understanding risk. They sample a moment, can be prepared for, and rarely reach workers' grievances or unauthorised subcontractors.

Mechanism

Disruption propagates through concentration

Single-source inputs, concentrated logistics hubs and shared sub-suppliers link firms that believe their chains are separate. A failure at one node becomes a sector-wide shock, and the governance questions follow the loss.

10Core questions

The questions experts ask.

  • How far does a company's responsibility extend into its supply chain?
  • How do firms identify and address human rights and environmental risks among suppliers?
  • How concentrated are critical supply chains, and where are single points of failure?
  • How do boards oversee supply-chain risk?
  • How do disclosure and due diligence laws change corporate behaviour?
11Mechanisms

Due diligence and resilience.

Human rights and environmental due diligence, as set out in international guidance such as the UN Guiding Principles on Business and Human Rights and the OECD due diligence guidance, asks firms to identify, prevent, mitigate and account for adverse impacts in their operations and value chains. A growing number of jurisdictions have made elements of due diligence mandatory. Practice varies widely, from audit-based approaches that check suppliers against codes to deeper engagement on purchasing practices that drive abuses.

Resilience is a related but distinct concern. Lean, concentrated supply chains reduce cost but increase vulnerability to disruption, as events affecting key producing regions have repeatedly shown. Visibility beyond direct suppliers is often limited, so firms may not know where critical inputs originate. Governance must balance efficiency, resilience and responsibility.

Boards increasingly treat supply-chain risk as strategic, but oversight depends on information that management often lacks below the first tier.

Purchasing practices are a governance lever that is often overlooked. Short lead times, last-minute order changes and price pressure can push suppliers to excessive overtime or subcontracting, so governance that looks only at supplier compliance, and not at the buyer's own conduct, can miss the root cause.

12Methods and data

Methods and their limits.

Mapping

Supply-chain mapping

Tracing suppliers and origins; visibility declines with each tier.

Assessment

Risk and impact assessment

Assessing human rights and environmental risks by country, sector and supplier.

Evaluation

Effectiveness studies

Studying whether audits and due diligence change outcomes; evidence is mixed.

Limits: audits can miss abuses, supplier data are often self-reported, and effects of due diligence laws are still being studied.

14Questions

Questions and answers.

What is risk-based due diligence?
The process, set out in the OECD Due Diligence Guidance for Responsible Business Conduct, by which a company identifies actual and potential adverse impacts, prioritises the most severe, acts to prevent or mitigate them, tracks results and communicates how they are addressed.
Is a supplier audit the same as due diligence?
No. An audit is one source of information at one point in time. Due diligence is a continuing management process that includes engagement with affected people, changes to purchasing practices and provision for remedy.
Who is responsible for impacts at a distant supplier?
Under the UN Guiding Principles and the OECD Guidelines, a company is expected to address impacts it causes, contributes to or is directly linked to through business relationships. The form of responsibility differs, and binding duties depend on national law.
Does Governance Nexus audit supply chains?
No. It convenes comparative study of governance and due diligence practices.
Is due diligence mandatory?
It depends on the jurisdiction. International guidance is voluntary; some countries have made elements mandatory.
Does this cover small firms?
Yes, including how due diligence obligations of large buyers affect smaller suppliers.
