CSRD and the Value Chain: Why Supplier Data Has Become a Strategic Asset

Temps de lecture : 7 minutes

For a long time confined to operational use (contract management, quality monitoring), supplier data is changing status with the entry into force of the CSRD. It becomes an essential component of sustainability reporting, climate strategy, and ESG risk management. Purchasing, CSR, Finance, Legal: more and more departments are now relying on this data, which ceases to belong to a single function to become a shared asset for the management of the company. And at the heart of this dynamic, the supplier evaluation becomes the concrete lever to structure this knowledge and make it usable.

Supplier data and CSRD: why all departments are concerned

For a long time, supplier data served an essentially operational. The Purchasing departments used it to manage contracts, track orders, assess quality, or secure supplies. The CSR, on the other hand, occasionally requested certain information to respond to a tender or feed into a non-financial report.

This organization is gradually becoming a thing of the past.

With the entry into force of the Corporate Sustainability Reporting Directive (CSRD), the environmental, social, and governance data of suppliers is changing status. They are no longer just used to qualify a supplier or to respond to a customer request. They are becoming an essential component of sustainability reporting, of the climate strategy, of the risk management and, more broadly, of the corporate governance.

In other words, the question is no longer whether to collect data from suppliers. The real question now is: how to build information that is sufficiently reliable, documented and usable to manage its sustainable performance?

The ambition of the CSRD and the Omnibus package

In this context, the CSRD is often presented as an evolution of reporting obligations. In practice, many companies have mainly experienced it as a long, complex, and costly process, with an operational benefit not always immediately perceptible. But the ambition of the directive is broader: it aims to improve the quality, the comparability and the reliability of the sustainability information published by companies. To achieve this, the companies concerned must apply the European Sustainability Reporting Standards (ESRS), which cover all dimensions of environmental, social, and governance.

This structuring ambition has nevertheless been perceived by some organizations as a administrative burden significant, hence the reflections initiated around the Omnibus package, published on February 26, 2026 and coming into force on March 18, 2026, to simplify and better prioritize the requirements. According to the publicized timeline elements, the compliance of member states on this aspect is set within a horizon extending to March 19, 2027 for the CSRD part, which reflects a desire for gradual landing rather than a sudden shift.

An expanded scope of information

This evolution profoundly changes the scope of information to be collected.

Until now, many companies focused their efforts on their own activities. From now on, they must also take into account the impacts, risks, and opportunities related to their value chain, when these elements are material in light of their double materiality analysis.

Part of the expected information is no longer found within the company itself. It is located with its suppliers. Supplier data becomes a shared asset.

A growing interest for many functions

Today, it therefore interests a growing number of functions:

• the Purchasing departments, which assess risks and support their suppliers in their maturity development
• the CSR departments, which consolidate the information necessary for sustainability reporting
• the Financial departments, which meet the expectations of investors and auditors
• the Legal and Compliance departments, which document the due diligence carried out as part of the duty of vigilance or other European regulations
• the General departments, which rely on this data to guide their climate strategy and responsible purchasing policy

Supplier data thus ceases to belong to a single department. It becomes a shared asset, mobilized in increasingly strategic decision-making processes. It also becomes an object of cross-functional governance, which requires functions to cooperate more to avoid duplications, inconsistencies, and unnecessary collections.

CSRD and value chain: what supplier data is actually expected?

Most of the issues covered by the ESRS are based, directly or indirectly, on information from the value chain. This is particularly true for:

• greenhouse gas emissions related to purchases (Scope 3)
• the working conditions at suppliers
• the human rights in the supply chain
• the traceability of certain raw materials
• the practices of circular economy
• the policies of responsible purchasing

A new way to know your suppliers

For companies, this means moving from a logic of one-off collection to a genuine approach of understanding their supplier ecosystem. The question is no longer just: "Who are our suppliers?"

It becomes: What are the most critical? Which are the most exposed to ESG risks ? What data is actually reliable ? What elements can be documented ? Where are the main levers for progress ?

Conclusion

At its core, the CSRD poses a simple question to companies: do you really know your value chain ?

For many organizations, the answer will no longer depend on the quality of their sustainability report, but on their ability to sustainably structure the collection, validation, and management of supplier data. It is on this capability that a large part of their ESG performance and their competitiveness.
