What Is CSRD? The EU Sustainability Reporting Directive Explained

What CSRD changes for corporate sustainability reporting, assurance, value-chain emissions and the evidence behind climate claims.

What Is CSRD? The EU Sustainability Reporting Directive Explained

The Corporate Sustainability Reporting Directive, or CSRD, is the European Union framework for mandatory corporate sustainability reporting. It expands the number of companies required to report, introduces detailed European standards and places sustainability information within a formal assurance environment.

What changes under CSRD

Companies report sustainability information in the management report using the European Sustainability Reporting Standards. Disclosures cover governance, strategy, impacts, risks, opportunities, targets and performance across environmental, social and governance topics.

The directive also requires digital tagging and external assurance. This moves sustainability data closer to financial reporting in terms of controls, documentation and accountability.

Climate and carbon implications

For climate, companies need a defensible greenhouse gas inventory across material scopes, a transition plan, targets and evidence of progress. Scope 3 often represents the largest data challenge because it relies on supplier, logistics, product-use and investment information outside direct operational control.

Carbon credits are reported separately from gross emissions. A company should therefore avoid presenting credit purchases as if they erase inventory emissions. The stronger approach is to show internal decarbonisation first, then explain any external climate contribution with project, volume and retirement details.

Assurance changes the standard of evidence

A claim that was once supported by a slide deck may now need source data, calculation files, approval records and registry documentation. Companies should define data owners, review controls and a consistent methodology before the reporting period closes.

For carbon procurement, this means keeping project due diligence, contracts, serial numbers, retirement beneficiaries and claim wording in one auditable file.

Building a CSRD-ready climate function

The practical sequence is to establish boundaries, complete the inventory, identify material hotspots, set transition levers and connect each disclosure to evidence. The process should be repeatable each year and capable of absorbing changes in organisational structure, supplier data and regulation.

Our emissions advisory work helps companies connect GHG accounting, targets, governance and market instruments into one reporting-ready system.
