Learn how CSRD impacts ESG reporting, who must comply, and how to prepare. Stay ahead of the EU regulations with this step-by-step guide. 2026 Update


As of February 2025, the European Commission introduced the "CSRD Omnibus," a proposal to update the Corporate Sustainability Reporting Directive (CSRD). After a year of negotiations, the Omnibus was formally adopted by the Council of the EU on 24 February 2026 and published in the Official Journal as Directive (EU) 2026/470 on 26 February 2026, entering into force on 18 March 2026. This is no longer a proposal — it is now law.
The directive significantly recalibrates CSRD obligations, reducing which businesses must report and easing the compliance burden for those that remain in scope.
Below, we've kept our original guide on CSRD intact but updated it throughout to reflect the final Omnibus changes, so you can see how they affect your compliance strategy.
The Corporate Sustainability Reporting Directive (CSRD) is an EU regulation designed to enhance transparency in corporate sustainability reporting. It replaces the Non-Financial Reporting Directive (NFRD) and requires companies to disclose their environmental, social, and governance (ESG) performance in a standardised, comparable manner. The directive is closely tied to the EU Green Deal, pushing businesses across Europe towards more sustainable practices and consistent reporting.
These changes aim to reduce compliance burdens while still advancing the EU's sustainability agenda.
If a company met two out of three of these criteria, it had to comply:
Under the final directive, only companies meeting both of these criteria must report:
This represents an approximately 80% reduction in mandatory coverage compared to the original CSRD. If you no longer meet both of these new thresholds, you fall out of scope for financial years starting on or after 1 January 2027.
Original Scope
Listed SMEs were previously within CSRD's scope, with simplified reporting standards. Non-listed SMEs were exempt but could be indirectly affected if they operated within the supply chains of larger companies bound by CSRD.
Omnibus Update
Under the Omnibus, all SMEs (listed or not) are out of scope for mandatory reporting. Listed SMEs gain a major reprieve. However, you may still choose to adopt the Voluntary SME (VSME) framework if demonstrating sustainable practices is important for your investors or clients.
SMEs also benefit from:
The Omnibus introduces an important new concept for smaller businesses. A "protected undertaking" is any company with fewer than 1,000 employees that sits within the value chain of a larger business required to report under CSRD.
Protected undertakings have the legal right to refuse information requests from reporting companies that go beyond what would be required under voluntary sustainability standards. Importantly, any contractual provisions that demand more extensive information are not binding. This gives meaningful protection to mid-market and smaller businesses that have historically faced pressure to supply detailed ESG data to their larger customers or partners.
If you are a supplier or subcontractor to a large in-scope company, this provision directly limits what they can legally ask of you.
Yes, it continues to apply if you generate more than €450 million in net turnover within the EU for each of the last two consecutive financial years, and have either:
Omnibus Impact: The final directive raises the non-EU parent threshold substantially — from €150 million in EU turnover (with a €40 million branch threshold) to €450 million, with a new €200 million subsidiary/branch floor. If your EU operations previously brought you into scope but no longer meet these revised figures, you may now fall out of mandatory reporting.
Revised Timeline (Post-Omnibus)
The timeline has been significantly restructured. The key dates under the final directive are:
Member State transposition: EU member states have until 18 March 2027 to transpose the directive's CSRD provisions into national law. The timing of national-level implementation may affect when certain exemptions become available in your jurisdiction.
Although the UK is no longer part of the EU, CSRD can still affect UK-based companies if:
UK SDR Alignment: The UK is developing its own Sustainability Disclosure Requirements (SDR). While the Omnibus doesn't directly alter UK SDR, it's wise to stay updated on both regimes if you operate across borders.
CSRD remains a legal obligation for large companies with 1,000+ employees and €450 million+ net turnover. However, listed SMEs, many mid-sized firms, and smaller businesses are now outside mandatory scope, greatly reducing the overall compliance burden.
For those that were previously in scope under Wave 1 but now fall below the new thresholds, the position is more nuanced. Member States may issue transitional exemptions covering FY2025 and FY2026, but you should monitor the position in your specific jurisdiction, as this requires national legislative action and may not be in place immediately.
Why Is CSRD Important?
Enhanced AccountabilityCSRD standardises ESG reporting, making it easier for investors and policymakers to compare sustainability performance.
Support for the EU Green DealBy 2050, the EU aims for climate neutrality. CSRD pushes businesses to adopt more responsible models, though the Omnibus softens obligations for smaller players.
Better Decision-MakingHigh-quality ESG data allows companies to identify long-term risks, from climate impacts to regulatory shifts.
Investor ConfidenceTransparent sustainability metrics attract sustainable investment funds and can improve market positioning.
CSRD's "double materiality" requires companies to examine:
Under the Omnibus, double materiality remains a central principle. The revised European Sustainability Reporting Standards (ESRS) introduce a streamlined, top-down approach with clearer criteria and fewer mandatory data points. Materiality assessments no longer need to be conducted every year, and the expectation has shifted from volume of disclosure to quality of judgement.
What's Changing with the Reporting Standards (ESRS)?
The European Sustainability Reporting Standards (ESRS) — which define exactly what in-scope companies must disclose — are being substantially revised. EFRAG submitted simplified Amended ESRS to the European Commission in late 2025, cutting mandatory data points by 61% and removing all voluntary data points across all 12 standards.
The revised ESRS are expected to be formally adopted by the Commission via a delegated act by mid-2026 (within six months of the directive entering into force). They will apply from financial years beginning on or after 1 January 2027, with optional early use for FY2026.
Key changes in the simplified ESRS include:
Until the revised ESRS delegated act is formally adopted, Wave 1 companies must continue applying the original ESRS Set 1.
Yes, but only if Scope 3 is material. This can include:
For companies still in scope (i.e., large firms with 1,000+ employees and €450M+ net turnover), Scope 3 remains important but can be more narrowly defined under the revised ESRS if it isn't materially significant. The new standards also allow greater use of estimates for value chain data, reducing the burden of direct supplier data collection.
Penalties vary by EU member state but typically include:
Fewer businesses will be subject to these penalties under the revised scope, but the penalty framework itself remains in place for those that are.
Conduct a Scope AssessmentCheck which threshold applies to you under the new rules: 1,000+ employees AND €450 million+ net turnover. If you were in Wave 1 but now fall below the new thresholds, monitor your Member State's position on the transitional exemption for FY2025 and FY2026.
Implement Robust Data CollectionWhile the Omnibus reduces reporting demands, large in-scope companies still need reliable ESG data. This includes Scope 1, 2, and (if material) Scope 3. The revised ESRS allow greater use of estimates for value chain data, which helps.
Update Your Double Materiality AssessmentThe revised ESRS introduce a streamlined, top-down approach. Your existing materiality assessment may need updating to reflect new definitions, aggregation options, and the clearer ability to omit non-material topics. Assessments no longer need to be redone annually.
Develop a Reporting StrategyAlign with the revised ESRS once the delegated act is published (expected mid-2026). Focus on double materiality, but expect fewer mandatory metrics and simpler requirements overall.
Ensure Governance and AssuranceLimited assurance stays in place, meaning you should still prepare for third-party reviews of your ESG data. The push towards stricter assurance requirements has been deferred.
Engage StakeholdersEven if you fall out of mandatory scope, voluntary ESG disclosure can be a market differentiator, especially if large clients or investors still demand sustainability data.
Know Your Rights in the Value ChainIf you have fewer than 1,000 employees and are receiving data requests from larger customers, you may qualify as a protected undertaking. Understanding this right can help you push back on requests that exceed voluntary standards.
