The CSRD is transforming the volume, granularity, and structure of ESG data available to investors. For institutional reporting teams, this is not just a regulatory development—it is a fundamental shift in how sustainability information informs portfolio monitoring.
A New ESG Disclosure Framework
The CSRD, applicable to the first large companies starting in fiscal year 2024, replaces the NFRD with a significantly more demanding framework. By the end of 2026, more than 50,000 European companies will be required to report in accordance with the European Sustainability Reporting Standards (ESRS), compared to approximately 11,700 under the previous regime. The first CSRD-compliant reports will be published in 2025 and early 2026.
However, the Omnibus Package presented by the European Commission in February 2025 significantly altered the course: the “stop-the-clock” directive postponed the obligations for the second and third waves of companies by two years, and the simplification proposals aim to raise the thresholds for compliance (notably to around 1,000 employees), which would significantly reduce the scope initially announced. The final details of the framework remain under negotiation at the time of writing. But the essence remains: the fundamental shift toward more ESG data reported by companies—audited and standardized—is underway and irreversible for European large-cap companies.
For institutional investors, this means that the pool of portfolio companies producing structured, auditable, and comparable ESG data is growing steadily, even though the pace and scope have been adjusted. Issuers that previously published sustainability information on a voluntary or inconsistent basis are now required to report on a standardized set of environmental, social, and governance indicators, subject to third-party verification.
What ESRS Reports Contain
The ESRS framework is structured around ten thematic standards covering environmental, social, and governance issues: climate change (E1), pollution (E2), water and marine resources (E3), biodiversity (E4), circular economy (E5), own workforce (S1), workers in the value chain (S2), affected communities (S3), consumers (S4), and business conduct (G1). Each standard defines qualitative information (policies, objectives, governance) and quantitative indicators (GHG emissions, energy consumption, pay gap, employee turnover).
Whereas the SFDR’s PAI indicators were based on a limited set of metrics often estimated by third-party providers, CSRD reports will gradually provide audited figures reported by companies across a much broader range of indicators.
From publication to portfolio integration: the real challenge
The challenge for institutional reporting teams is not the existence of this data, but its integration into portfolio monitoring. CSRD reports are published annually in various digital formats and must be reconciled with existing ESG data feeds (MSCI, Sustainalytics, Bloomberg). Each provider has its own taxonomy, rating methodology, and coverage universe. The introduction of company-reported ESRS data adds complexity rather than simplifying the landscape.
Key questions for institutional investors: how to reconcile CSRD metrics with existing third-party ESG scores, how to manage the transition period during which only some companies report under CSRD, how to integrate this data into fund-level transparency, and how to ensure that ESG reporting reflects the most reliable data without duplication.
Lookthrough and double materiality
For investors holding fund portfolios, ESG analysis requires greater transparency: understanding the ESG characteristics of the underlying assets in each fund. With the expansion of data under the CSRD, this process becomes more comprehensive but also more demanding. An insurer holding 200 funds across multiple managers must reconcile ESG data from third-party providers with that from issuers’ CSRD reports, on a large scale and with full traceability. This is an infrastructure challenge, not a manual exercise.
The CSRD also introduces dual materiality: companies must report on the impact of sustainability factors on their financial performance, and on the impact of their operations on the environment and society. For investors subject to the SFDR or producing ESG reports for pension fund beneficiaries, this means that ESG analysis can be structured along both axes, requiring an infrastructure capable of tagging, filtering, and presenting metrics based on financial risk, societal impact, or both.
What this means in practice
ESG data now supports multiple regulatory requirements: periodic SFDR reporting, Solvency II ORSA, IORP II pension fund reporting, and voluntary frameworks such as the TCFD or the European Taxonomy. Rather than maintaining separate data pipelines for each requirement, institutional investors benefit from a single, validated ESG dataset that is segmented and presented according to the requirements of each framework.
For reporting teams, the priorities are clear: establish a process for ingesting CSRD metrics, define reconciliation rules with data from existing providers, update ESG models to reflect the expanded set of indicators, and ensure that transparency disclosures capture CSRD data when available. None of this is feasible at the institutional level without a robust data infrastructure. The question, therefore, is no longer whether this data will arrive, but how to leverage it: build this infrastructure in-house, or rely on a platform that has already industrialized it.
A constantly evolving framework: regulatory monitoring is essential
Finally, it is important to bear in mind that this regulatory framework is far from set in stone. In just a few years, the landscape has shifted from the NFRD to the CSRD, then to the adjustments introduced by the Omnibus Package, not to mention parallel developments in the SFDR, the European Taxonomy, and the ESRS standards themselves, for which simplification is already under consideration. Thresholds, timelines, and disclosure requirements will continue to evolve as European negotiations and national transpositions unfold. For institutional investors, active and continuous regulatory monitoring is therefore not optional: it is essential for anticipating changes, adapting reporting processes proactively rather than under pressure, and ensuring that the data infrastructure remains aligned with current requirements. Organizations that integrate this monitoring into their internal systems or through their partners and platforms will be able to handle each regulatory change with a simple configuration update, whereas others will see each one as a new project.
