CSRD: From Compliance to Opportunity

13 Οκτ 2026 · @Nikos Stavropoulos

Introduction

The Corporate Sustainability Reporting Directive (CSRD) is usually discussed as a cost, but the research on mandatory disclosure suggests that its value depends on what a company does with the information it is forced to collect. The Directive (EU) 2022/2464 replaced the earlier Non-Financial Reporting Directive and introduced the concept of double materiality: a company reports both how sustainability issues affect its finances and how its own activities affect people and the environment [1]. The rules have changed substantially since 2022. A 2026 "Omnibus" package narrowed the scope of the Directive and the Commission has adopted simplified reporting standards [2][3][6]. This article sets out where the CSRD stands today, what the empirical literature says about mandatory disclosure, and how a company can turn a reporting obligation into better decisions. Where a statement is my inference rather than a finding of a cited study, it is labelled as such.



What the CSRD requires today?

Since the Omnibus I Directive, the CSRD applies only to the largest companies, and the standards that define what they report have been shortened. The Omnibus was published in the Official Journal on 26 February 2026 as Directive (EU) 2026/470 and entered into force on 18 March 2026 [2][3].



Member States must transpose the CSRD changes by 19 March 2027 [2][3]. The Commission must also review the scope thresholds by 26 July 2031 [2].

On the standards, EFRAG sent its technical advice on revised ESRS to the Commission on 3 December 2025. It proposed a 61% cut in mandatory datapoints, although the law firm Linklaters cautions that much of this reflects de-duplication rather than a lighter burden [4]. The Commission published a draft in May 2026 that keeps double materiality and adds a top-down approach to the assessment [5]. EFRAG reported on 22 September 2026 that the revised ESRS and a Voluntary Standard for companies with fewer than 1,000 employees had been adopted and published in the Official Journal [6]. One adviser's summary states entry into force on 10 November 2026, mandatory application from financial year 2027 and voluntary application for 2026 [7]. Those dates come from a secondary source, so check them against the Official Journal text before relying on them. If your company has fewer than 1,000 employees, it is probably not directly in scope. My inference is that it may still receive data requests from larger customers, which is where the value-chain cap and the Voluntary Standard become relevant [2][6].

Cost or information? What the evidence says.

Mandatory sustainability disclosure tends to reward companies that already perform well and to push weaker ones to change, which is why the same rule is a burden for some and an advantage for others. Four studies of mandatory regimes point in this direction.

• Market reaction. Around the events leading to the EU's earlier non-financial reporting directive, equity markets reacted negatively on average (−0.79%). Firms with weak prior ESG performance and disclosure averaged −1.54%, while firms with strong prior performance and disclosure averaged +0.52% [8].
• Real change. After the same directive took effect, in-scope firms increased their CSR activities, mostly those that had low CSR reporting and activity before. The authors find signs of real improvements rather than greenwashing [9].
• Liquidity. Across countries, mandatory ESG disclosure improves firm-level stock liquidity. The effect is stronger when governments impose the rules rather than comply-or-explain regimes, and for firms with weaker information environments [10].
• Overall assessment. A broad review of the accounting, finance and management literature finds consequences for capital markets, for stakeholders other than investors, and for firm behaviour, and it stresses that the outcome depends on implementation and enforcement [11].

A separate study looks at what sustainability-minded companies do differently. Among 180 matched US firms, those that adopted sustainability policies early more often gave their boards responsibility for sustainability, linked executive pay to it, engaged stakeholders systematically and measured non-financial information more widely. They outperformed on stock market and accounting measures over the long term [12]. This is an association between two groups of firms, not proof that sustainability caused the performance. My reading of these results, not a finding of any single study, is that the disclosure itself is rarely where the value comes from. The value comes from the management processes that a credible disclosure forces a company to build.

Double materiality as a strategic tool

Double materiality forces a company to look at its business from two directions at once, and that is the most strategically useful part of the CSRD. The revised ESRS keep it [5][7].

A review article on the shift from non-financial to European sustainability reporting covers double materiality, its outlook and its implications [13]. Separately, a literature review contrasts reporting approaches with different overarching goals and materiality standards [11]; I read this as the same distinction that now separates the ESRS from the investor-focused ISSB standards, though that review predates the ESRS. The Commission's draft keeps the ESRS distinct from ISSB, tells companies not to report non-material information except in defined cases, and adds a top-down option for the assessment [5]. The examples in the table are my illustrations. In practice, my inference is that a well-run materiality assessment is a structured list of the risks, impacts and opportunities that matter to the business, ranked and owned. A company can use that list for its strategy and risk register even if the final report is short.

From data to decisions: where the opportunities are

The opportunity lies in using the data a company must now collect for decisions that the report itself does not require. The sources support four directions, with different strength of evidence.

1. Better governance. Companies with long-standing sustainability practices more often have board oversight, pay links and stakeholder processes [12]. Building these for the CSRD may therefore bring the same governance habits, though the evidence is associational.
2. Capital and market credibility. For listed firms, mandatory disclosure is linked to better stock liquidity, especially where information was weak before [10]. The market reaction study suggests that firms with strong prior performance gain from disclosure, while weak ones lose [8].
3. Change in conduct. Firms with little prior CSR activity increased it after a reporting mandate, apparently in real terms [9]. For a company, the reporting cycle can serve as a deadline-driven way to set and track targets.
4. Supply-chain position. Large in-scope companies will keep asking suppliers for data, within the limits set for partners under 1,000 employees [2]. The Voluntary Standard offers smaller firms a common format to answer with [6]. My inference is that a supplier able to answer quickly and consistently is easier to buy from.

For consultants and companies using management systems, my inference is that an ISO 14001 or ISO 9001 system already supplies much of what the CSRD needs: defined processes, owners, records and internal audit. I have not found a study that tests this link directly, so treat it as a working hypothesis.

A practical roadmap and the limits of the evidence

A company can start in six steps, and the first two decide how much of the rest it needs. This sequence is my practical suggestion, not taken from a cited study.

1. Confirm your status. Decide whether you are in scope directly, receive requests as a supplier, or report voluntarily.
2. Run a proportionate double materiality assessment. List impacts, risks and opportunities, and record why each is or is not material.
3. Map the data. Compare the datapoints you need with those you already hold, and note gaps and owners.
4. Set controls. Assign responsibility and keep evidence, since the reported data will be assured.
5. Use the results. Feed priorities into budgets, targets, supplier talks and risk registers.
6. Track the rules. National transposition is due by 19 March 2027 and the standards may still be adjusted [2][6].

Limits. Most cited studies examine the earlier non-financial reporting directive or other regimes, mostly for large listed firms, so none yet measures the outcome of the CSRD as amended. The market reaction study uses a short event window [8]. The study of early adopters shows association, not cause [12]. The rules and dates in this article reflect sources I opened in October 2026, and several are law-firm summaries, so confirm legal details against the Official Journal before advising a client.
