What the New CSRD Rules Mean for Businesses and Why They Matter

The Corporate Sustainability Reporting Directive (CSRD) provides a feast of EU measures for greater corporate transparency on environmental, social and governance (ESG) issues — dating back to 2022. 

There have been a number of important changes (mostly driven by the “Omnibus” simplification package) in its scope and requirements through the 2025 period with the aim of cutting administrative burden while still targeting high-impact companies. 

Entering 2026, these modifications are a reprieve for many businesses, they also underscore the need for sustainability reporting by larger ones.

This article will discuss a snapshot of the CSRD regime to which businesses subject, what they need to report and finally—most importantly—why it is important for businesses operating in or working with companies that operate in the EU.

What Is the CSRD and How Has It Evolved?

The CSRD is replacing the existing Non-Financial Reporting Directive (NFRD), which aims to increase and harmonize requirements on disclosure of sustainability impacts and risks by companies. 

Reporting will be in line with the European Sustainability Reporting Standards (ESRS), which focuses on “double materiality,” addressing not only how a company’s economic position might be influenced by sustainability issues (financial materiality) but also how its activities affect people and the environment (impact materiality).

• The Omnibus package was brought in by the EU in 2025 to simplify rules on competitiveness an administrative costs. Key outcomes include:
• Narrowed issue: Imposing obligations just on the largest companies.
• Deferrals: For some batches of companies.
• Simple ESRS: Data reduction and the introduction of proportionality in reporting.

These changes, which were finalized through interim agreements in late 2025 (but are retroactive in some cases) attempt to reduce the number of in-scope companies dramatically— perhaps as much as 80-90% less than originally anticipated.

Who Is Affected by the Updated CSRD Rules?

The original CSRD was supposed to apply to around 50,000 companies but the 2025 revisions will reduce this substantially.

Under the revised rules:

• EU companies: Now mostly those with more than 1,000 or 1,750 employees and at least €450 million in turnover. Most listed SMEs and many medium-sized companies are effectively exempt or can opt out.
• First-wave companies (large public-interest entities previously in scope of NFRD, typically >500 employees): Already reporting since FY24 (published 2025), some alleviation on supplementary data points for 2025-2026.
• Non EU companies: Parent entities with material EU activity (e.g., >€450 million EU turnover) might be subject to a group level reporting, but pushed back in time.
• Exemptions and delays: Many second- and third-wave companies (originally 2026-2027) now have postponements until 2028-2029 across various exemptions.

Even if your business is beneath those higher thresholds, you may not be off the hook — indirect pressures from long-distance clients can still apply pressure.

Key Reporting Requirements Under the ESRS

Qualifying entities are required to report in the ESRS: The ESRS have been simplified in 2025 as follows forCellular companies Subleases Other qualifying entities must report according to defined schedules in the ESRS.

Cross-cutting standards: Overall disclosures on strategy, governance and materiality.

Topical issues: Including environment (e.g., climate change, pollution, diversity), social (e.g., workforce, value chain workers; communities) and governance (e.g., business behaviour).

Phase-ins and relief: Expanded for difficult areas like value chain impacts, or a financial effect; risk-based approaches are permitted.

Form and assurance: Digital tagging for machine-readability; third party assurance expectations would be limited initially, but might progress to partial reasonable assurance later.

Alignment with EU Taxonomy on sustainable activities.

Reports can form the basis of annual management statements which contain forward-looking as well as backward, both quantitative and qualitative information.

Why the CSRD Still Matters for Businesses

Svejnar Even with the simplifications, CSRD is game-changing for in-scope companies and impactful for those out-of-schroeder (1)Amsterdam Business School referred to subsequently as Amsterdam Business School – University of Amsterdam, Netherland. Here’s why it demands attention:

Enhanced Transparency and Accountability

And the directive also would mean stakeholders — investors, customers regulators — get dependable, comparable ESG data. This limits greenwashing and helps to generate trust in a time when sustainability statements are being challenged.

Capital and Comparative Advantage

Investors increasingly prioritize ESG performance. Significant CSRD compliance can draw the green financing, reduce the cost of capital and differentiate your brand. On the other hand, bad disclosure can result in PR fires or missed openings.

Risk Management and Resilience

Double materiality requires businesses to consider sustainability risks (such as climate effects on operations) and impacts (like emissions on the environment). This encourages smarter strategy, innovation in sustainable practice and long-term resilience.

Supply Chain Ripple Effects

And even if you are out-of-scope, companies may still report data requests passed on from their large partners that do need to comply with value chain disclosures. “Pro-active reporting will put SMEs who are good suppliers, which is the majority – not all but most consumers – in a really strong position.

Alignment with Global Trends

CSRD influences the standards that are starting to develop in other countries (e.g. possible cross-referencing to ISSB or U.S. SEC rules). Preparation early Preparing now, means your business is future-proofed against developing global ESG regulation.

Contribution to Broader Goals

At heart, CSRD is about backing the EU Green Deal and Paris Agreement goals by directing business towards net zero and sustainable development.

Preparing for the Future

For in-scope companies, 2026 is business as usual: begin conducting double materiality impact assessments / gap analysis to the simplified ESRS, establish robust data systems.

For the rest, voluntary convergence, and simplified standards (e.g., VSME) can deliver benefits without imposing requirements.

The new CSRD seeks to strike a balance: alleviating some of the loads and maintain the spotlight on sustainability. Those that adopt it — not just comply with, but actively embrace — will best be positioned to succeed in a transparent, sustainable economy.

Impacted or not, the writing is on the wall: sustainability reporting is no longer a “nice to have,” it’s required (if you plan on remaining in business).
