Overview

The ESRS expect undertakings to consider upstream and downstream value chain effects. The law does not require perfect information on day one, but it does require a disciplined approach to collecting what is available, estimating what is not yet available, and explaining the efforts made, the remaining gaps, and the improvement path.

Section 1

Start with a value chain perimeter, not with a supplier survey

The first step is to define which upstream and downstream activities are relevant to the reporting boundary and the material matters identified. Only then should the company design data requests and evidence logic.

A survey first approach usually produces a lot of low value data and weak coverage of the real risks and impacts.

  • Define upstream and downstream perimeter linked to material matters.
  • Identify the highest value data dependencies first.
  • Separate mandatory data from useful but optional enrichment data.
Section 2

Use a clear data hierarchy

A practical hierarchy starts with internal systems and controlled partner data, then moves to credible third-party datasets and structured estimation where direct data is missing. The hierarchy should be disclosed internally so reviewers know what they are looking at.

Do not mix measured and estimated data without labels.

  • Priority 1: internal and controlled direct partner data.
  • Priority 2: external verified or credible dataset inputs.
  • Priority 3: documented estimation models with assumptions and validation checks.
Section 3

Document best efforts and remaining gaps

Where not all necessary value chain information is available, the report should explain the efforts made to obtain it, why the information could not be fully obtained, and how the company plans to improve availability in the future. This is a legal disclosure point, not just a project management note.

That means the collection log matters.

  • Keep outreach records and response rates.
  • Record why data gaps remain after outreach.
  • Publish the improvement path in a controlled way.
Section 4

Review estimates like financial reporting estimates

Estimated value chain information should be reviewed with the same seriousness as significant financial reporting estimates. That means clear assumptions, validation, sensitivity awareness where relevant, and management review.

Treating value chain estimates as informal ESG placeholders is a direct route to assurance issues.

  • Document assumptions, calculation logic, and validation steps.
  • Flag where estimates carry higher uncertainty.
  • Retain reviewer and approver sign off.
Recommended next step

Operationalize EU CSRD (Directive (EU) 2022/2464) Value chain data and estimation across ESG workflows

ESG Compliance can take EU CSRD (Directive (EU) 2022/2464) Value chain data and estimation from operationalizing this sustainability obligation across workflows and reporting to a reusable workflow inside Sorena. Teams working on EU CSRD (Directive (EU) 2022/2464) can keep owners, evidence, and next steps aligned without copying this guide into separate documents.
