Supply chain due diligence: what directors need to know in 2026

Supply chain due diligence: what boards of directors need to know as regulators and other stakeholders increase their scrutiny of your business. 

Supply chain due diligence covers all the analysis of supply chains, primarily to make sure they conform to ethical principles. These days, most of those principles are defined by regulators and the companies’ individual mission statements and codes of conduct. 

While the 2020s have seen multiple governments “loosen” their scrutiny of corporations in the name of competitiveness – or even just out of principle – it hasn’t really had the effect of lessening the need for due diligence. There are two reasons:

1. Other stakeholders, like consumers and investors, continue their hawkish scrutiny of companies to ensure ethical supply chains. 
2. Many governments remain committed to supply chain due diligence through legislation, meaning that, at some point, compliance requirements might catch up with you. 

An example of the second point above is the Corporate Sustainability Due Diligence Directive (CSDDD), which is moving toward full application in the European Union. Delayed in the short-term, but remaining on the cards for the longer-term, it will force directors to recognise that the many moving parts within their supply chains, and how they might impact others in ways that violate ethical principles.

Because the EU has consistently ranked as a leader in regulator-fuelled due diligence compliance, you’ll find that the rest of this article speaks from that geographical context. Be warned, however, that if you think this means any regulator-enforced rules might never apply to you, they could if you are part of a supply chain feeding a company headquartered inside EU borders.

Bad news first: the parameters of directors’ roles in supply chain due diligence will likely change more throughout the rest of the decade. 

The good news, though, is that finalisation of the information, like the Sustainability Omnibus I package, has provided at least some necessary clarity for boards to put a practical roadmap together.

Good boards can think strategically, zooming out when they need to to understand the big picture. However, some boards might forget to apply this mentality when looking at the company’s supply chain. 

Make no mistake: this is essential at every stage from raw materials onwards. In many cases, this involves asking the same questions that might come up about your own company’s operations. You need to fully comprehend how your mission statement and code of conduct are playing out in these associated entities and, if there are conflicts, you need to be prepared to act. 

To help, it’s useful to quantify and standardise as far as possible with meaningful reporting standards. 

Why it matters for directors: 

The gap between policy and implementation is a long-running problem for many businesses, and supply chains are hotbeds for it, since you’re trying to apply the same oversight to different entities. However, nowadays, non-compliance with regulations in this area could lead to significant financial penalties. One way or another, the blame for those penalties is going to come back to the board.

Risk, in general, requires a lot of in-depth analysis. The same holds in supply chain due diligence, and you can read more about it in the “risk-based approach” codified by the OECD Due Diligence Guidance. 

When analysing risk from a due diligence perspective, it’s all about those who might be affected in any way by the supply chain’s activities. Practically, that usually means local communities, employees, and those living close to resource extraction sites. Your job as an overseer is to question how severe any impact on these communities might be. 

Why it matters for directors: 

We’re in an era defined by transparency, whether you want it or not. Therefore, any failure in risk management could cause extreme harm overnight, and all of it will be documented. Directors are a key link in the effort to make sure this doesn’t happen.

Traditionally, contracts between companies and their supply chain partners were designed to be “risk-shifting”, essentially shifting the burden of risk management down the line, so the board of the primary company wouldn’t need to bother with it. Now, however, there’s far greater stability in “shared responsibility” in this area. Forward-thinking boards will use tools like the Model Contract Clauses 2.0, which focus on cooperation rather than creating an “us or them” mentality. 

Why it matters for directors: 

Modern regulations like CSDDD are written specifically to stop the old way of firms simply transferring their risk obligations. Regulators have recognised that this doesn’t solve anything when it comes to supply chain due diligence. Failing in this area will mean repercussions for the board.

Modern supply chains are making use of agentic AI systems, capable of doing things like supplier screening and real-time monitoring. It’s rapidly becoming a hallmark of modern supply chain leadership, and while it can be a huge enabler, it does carry certain specific risks that need directors’ attention. They are the ones who must oversee any decision (or suggested decision) made by these AIs.

Why it matters for directors: 

Directors are in place to question any strategic decision about business operations. If some of those decisions now emerge through the use of AI, then directors need to factor AI management into their areas of expertise. Crucially, it ensures there’s “human-in-the-loop” from the top down.

Supply chains are big structures with many moving parts, and not every stakeholder will likely be happy all of the time. 

Addressing that unhappiness and taking steps to remedy it is one important part of the overall goal: build trust with every stakeholder along the chain. 

This relies on good communication – accessible, predictable, and transparent. Research into supply chain due diligence trends suggests that a lack of meaningful stakeholder dialogue is increasingly viewed as evidence of a weak due diligence system.

Why it matters for directors: 

Directors must always take the lead in communication, no matter what the issue is. Communication is a top-down responsibility: when it goes well at the highest levels, that will generally filter down. 

Supply chain due diligence in 2026 is all about pro-activeness. Previous governance models might have allowed directors to pass any decision-making and risk responsibility down the line, often ending up entirely with suppliers themselves. 

Nowadays, regulators and consumers are savvy to this way of thinking, and they’ve wasted no time in declaring it sub-standard. As a result, directors need to share the burden or risk and make decisions after consultation with varied stakeholders. This will ensure a robust strategic future.
