CSRD requires in-scope EU undertakings to report sustainability information under the ESRS, inside the management report, tagged in digital format and subject to at least limited assurance. Scope follows size thresholds and listing status, with non-EU parents captured through a separate regime, and the phase-in has been rescheduled by the Omnibus package. What you report is set by your double materiality assessment; how fast you can report it is set by your data architecture.
CSRD replaced the Non-Financial Reporting Directive and moved sustainability reporting into the same regime as financial reporting: in the management report, in a machine-readable format, and assured. The 2025 Omnibus package then reopened both scope and timing, so a group's obligation date is now a function of its size class and wave.
For finance leaders the practical question is not the legal text. It is which datapoints apply, which systems hold them, and whether the numbers can survive an assurance provider tracing them back to source. That work takes at least one full reporting cycle to build.
The Omnibus package postponed reporting for later waves and reduced the population caught by the first waves. Confirm your own wave against the current directive text and the Dutch implementing legislation before you plan the build — the dates have moved more than once.
The report follows ESRS structure regardless of size. Two cross-cutting standards always apply; the topical standards apply only where your materiality assessment says they do.
Sustainability data behaves like financial data under assurance: it needs a defined source, a calculation, a boundary and an owner. Most groups discover that half their datapoints have none of these.
Scope depends on the transposition in each member state and on the phase-in as amended, but it is built on size thresholds for large undertakings and listed SMEs, plus separate rules for certain non-EU parent groups. Confirm the current national scope before concluding a group is out.
