CSRD vs NFRD: What Actually Changed for Sustainability Reporting

The Non-Financial Reporting Directive (NFRD) governed EU sustainability disclosure for roughly six reporting years before the CSRD replaced it. If you filed under the NFRD, the honest summary of the change is this: the topics are familiar, and almost nothing else is.

The NFRD told you what subjects to write about and left the rest to you. The CSRD tells you which data points to publish, in which format, verified by whom. That is a difference in kind, not degree — and it explains why companies that had been reporting for years still found their first CSRD cycle hard.

The Short Version

• Scope — from about 11,700 companies to roughly 50,000 under the original CSRD, before the Omnibus package cut that back.
• Standards — from "pick a framework" to the mandatory ESRS.
• Materiality — from a single lens to double materiality.
• Assurance — from none to mandatory limited assurance.
• Format — from a PDF to digitally tagged, machine-readable data.
• Placement — from a separate statement to the management report.

Each of these is worth unpacking, because the practical burden lands unevenly.

What the NFRD Required

Adopted in 2014 as Directive 2014/95/EU, the NFRD amended the EU Accounting Directive and applied from financial year 2018. It covered large public-interest entities with more than 500 employees — listed companies, banks, and insurers — which worked out to roughly 11,700 companies across the EU.

Those companies had to publish a non-financial statement covering:

• Environmental matters
• Social and employee matters
• Respect for human rights
• Anti-corruption and bribery

For each, they described their policies, the outcomes of those policies, the principal risks, and relevant non-financial KPIs. Where a company had no policy on a given matter, it could simply explain why — the "comply or explain" approach.

Crucially, the NFRD did not specify a reporting standard. Companies chose their own: GRI, the UN Global Compact, ISO 26000, TCFD, or an in-house framework. The Commission published non-binding guidelines, but nothing obliged anyone to follow them.

What Changed, Point by Point

1. Scope

The NFRD's 500-employee public-interest test kept it to large listed groups. The CSRD extended reporting to large companies generally — including unlisted ones — plus listed SMEs and non-EU groups with significant EU turnover.

The original expansion was to roughly 50,000 companies. The Omnibus has since raised the thresholds substantially and made listed SME reporting voluntary; the current position is set out in our CSRD timeline guide. Even after that reduction, CSRD scope remains far wider than the NFRD's, and it reaches company types — large private groups, non-EU parents — that had never reported at all.

2. From Frameworks to Standards

This is the change that generates the most work.

Under the NFRD, a company decided what to disclose and how to structure it. Two companies in the same sector could produce non-comparable reports and both be compliant. That flexibility was the directive's central weakness: investors could not compare, and the resulting data gap was the stated reason for replacing it.

The CSRD mandates the European Sustainability Reporting Standards (ESRS) — 12 standards covering cross-cutting requirements, five environmental topics, four social topics, and business conduct. Each carries defined disclosure requirements and specific data points, with prescribed metrics and prescribed structure.

If you reported under GRI, much of your underlying data carries over. The way you present it, and the completeness expected of it, does not. Our framework comparison guide covers where GRI, ISSB, and TCFD map onto ESRS.

3. Double Materiality

The NFRD used the phrase "double materiality" only in the Commission's non-binding guidelines. In practice, most companies applied a single lens — usually whichever one suited the audience they cared about.

The CSRD makes double materiality a legal requirement and the mechanism that determines the entire scope of your report. You assess impact materiality (how your business affects people and the environment) and financial materiality (how sustainability matters affect your financial position) — and a topic is material if it clears the threshold on either.

The assessment is now the load-bearing element of the report. Get it wrong and every disclosure decision downstream inherits the error, which is why it gets a guide of its own.

4. Assurance

The NFRD required no external assurance of the content. Auditors checked that a non-financial statement had been provided — not whether what it said was supportable.

Under the CSRD, sustainability information requires limited assurance from the first report, with the Commission developing reasonable assurance standards by October 2028. That single change reclassifies sustainability data from communications output to audited disclosure, with the internal controls and evidence trails that implies. See our assurance and audit requirements guide for what auditors actually test.

For NFRD veterans this is usually the biggest shock. The narrative you wrote for years was never challenged on evidence. Now it is.

5. Digital Tagging

NFRD statements were published as documents — PDFs, mostly, sometimes only as part of a glossy annual review.

CSRD reports must be prepared in XHTML and digitally tagged using the ESRS taxonomy, so that disclosures are machine-readable and can be ingested into the European Single Access Point. It is a technical workstream with its own tooling and its own failure modes; our XBRL and digital tagging guide covers it.

6. Placement in the Management Report

The NFRD permitted a separate report published alongside the annual accounts. The CSRD requires the sustainability statement to sit in a dedicated section of the management report.

This sounds administrative and isn't. It puts sustainability disclosure inside the document the board signs, on the same timetable as the financial statements, under the same director liability regime. Sustainability reporting stops being a spring project owned by the communications team.

If You Reported Under the NFRD

You are in Wave 1 and have already filed at least one CSRD report. Three things tend to carry over well and three tend not to.

Carries over: your topic list, most of your environmental metrics, and your stakeholder relationships. The underlying subject matter did not change, and neither did the people you talk to about it.

Doesn't carry over: your materiality assessment, if it only ever looked outward-in; your evidence trail, which was never built for an auditor; and your reporting calendar, which now has to align with the financial close rather than trail it by months.

The teams that had the smoothest transition were the ones that treated the first CSRD report as a controls project rather than a writing project. The teams that struggled were the ones that started from last year's NFRD statement and tried to extend it.

Is the NFRD Still Relevant?

As law, no — the CSRD repealed and replaced it. But it remains useful as a reference point in two situations.

The first is internal. If your organisation still refers to "the non-financial statement" or budgets for it as a communications deliverable, the vocabulary is telling you the operating model never actually changed.

The second is comparative. Wave 1 reports covering FY 2024 are the first CSRD filings, and the NFRD statements that preceded them are the only baseline available for showing a board how much the disclosure surface has grown.
