- The CSRD reporting framework is defined by the ESRS standards: 12 ESG topics, mandatory and audited.
- Double materiality is the guiding principle for selecting what to disclose.
- Reporting is integrated into the management report and subject to external assurance.
- Some sectors face reinforced disclosures; others report according to their own materiality analysis.
What is the CSRD reporting framework?
The CSRD is the European directive requiring large companies and mid-sized companies to publish complete sustainability reports. It replaces voluntary approaches with a precise normative framework defined by the ESRS. These standards set the ESG content to disclose, the expected granularity and the audit consistency. The main objectives are the standardization of ESG reporting, transparency of data for stakeholders, and accountability of leaders, with extra-financial performance now integrated at the same level as financial results. For the reporting process itself, see our guide to CSRD reporting.
Companies concerned and implementation timeline
The CSRD scope covers large companies and certain mid-sized companies. Unlisted SMEs are not directly bound; they can draw on the voluntary VSME standard developed by EFRAG to answer their clients' or bankers' requests. Application is progressive: some large companies already report under this framework ("wave 1"), while a second wave follows. Detailed thresholds by size and status should be confirmed against the applicable regulatory annexes.
Key obligations: ESRS standards and double materiality
The ESRS are the technical foundation of the CSRD. They cover 12 ESG topics and impose precise requirements of collection, traceability and auditability. Double materiality is the guiding principle: companies must analyze both the impact of their activities on the environment and society, and the impact of sustainability issues on their financial performance and risks. This approach structures KPI selection, strategic priorities and the hierarchy of data to disclose.

How to prepare operationally for CSRD reporting
Governance and oversight
ESG topics must be overseen at the highest level, with roles and responsibilities clearly defined within the executive committee.
Data and systems
Reliable reporting requires centralizing all ESG data on a single platform, ensuring traceability and consistency across departments (finance, HR, operations, procurement).
Internal controls
As external audit is mandatory, internal controls must match the financial level of requirement: complete documentation, verified sources, reproducible processes.
Indicator selection
Indicators must cover at least 80% of the operational scope and be tracked over several years to demonstrate progress. See our guide on CSRD indicators.
Assurance, audit and reporting reliability
The CSRD makes external audit mandatory. Companies must prove the quality and consistency of their files through cross-functional governance involving finance, operations and legal. Best practices include cross-verification of data between departments, use of a central tool for traceability, and consistency with the ESRS standards integrated in an internal audit cycle.
Comparison: CSRD vs other reporting frameworks
| Framework | Nature | Specificities |
|---|---|---|
| CSRD / ESRS | Regulatory, mandatory | External audit, double materiality, integration in the management report |
| NFRD | Former European framework | Fewer indicators, no double materiality, narrower coverage |
| VSME | Voluntary, for SMEs | Far less data to collect, no mandatory audit |
| GRI / IFRS / CDP | Voluntary / international | Growing alignment with ESRS, complementary to prepare CSRD reporting |
Alignment between the CSRD and other standards (CDP, EcoVadis, ISO, see CSRD vs GRI) allows reusing a large part of already-collected data, reducing the administrative burden.
Sectoral specificities
Some activities are subject to reinforced disclosures: fossil energy (revenues from exploration, extraction or refining), chemicals (pesticide or agrochemical production), tobacco (cultivation or production revenues), and financial services (specific obligations aligned with prudential frameworks and climate transition risks). For other sectors, requirements stem from a materiality analysis specific to each business model.
Common challenges and key steps
The main challenges concern data volume, the cross-functional nature of ESG topics and the complexity of double materiality. Advanced companies proceed by assessing their maturity from existing frameworks (ISO 14001, EcoVadis, CDP), mapping resources and assigning responsibilities per ESG pillar, centralizing data before internal audits, and formalizing policies and action plans. For SMEs out of scope, this preparation remains strategic to answer the expectations of their in-scope clients.
