CSRD in the public sector: scope, obligations and implementation

The logic and objectives of the CSRD in the public sector

The CSRD standardizes sustainability reporting in Europe, requiring large companies and mid-sized entities to disclose ESG performance under the ESRS. Its main goal is transparency: comparable, auditable data integrated into strategic steering. In the public sector, the same requirement applies to bodies whose activity, size or legal structure resembles that of a large company or significant economic operator.

Which public entities are concerned?

The CSRD scope in the public sector covers public companies (mixed-economy or national/local entities with significant market activity) and industrial and commercial public establishments managed like private firms, when they exceed the "large company" thresholds. Administrations and local authorities are not directly targeted but increasingly publish environmental and social information in their performance reports. The determining criterion remains economic size (headcount, turnover, consolidated balance sheet).

Reporting requirements in the public sector

Concerned public entities must: apply the ESRS across ESG topics (governance, climate, social, human rights, public ethics); demonstrate double materiality; undergo mandatory external audit; and publish in the standardized digital format (ESEF/XBRL) for traceability and comparability.

Building a CSRD roadmap for public entities

1. Governance and steering: a CSRD steering committee attached to general or financial management, ensuring strategic oversight and compliance.
2. Materiality mapping: identify priority ESG issues under double materiality (impact of public missions and exposure to environmental/social risks).
3. Data collection and reliability: a centralized ESG platform to consolidate financial, HR and environmental data with verifiability.
4. Report production and assurance: prepare the integrated report with the external auditor, using the relevant ESRS and the ESEF/XBRL format.
5. Training and upskilling: support business teams for a consistent understanding of indicators, framework and internal controls.

Information systems and data control

Public entities need tools ensuring full traceability of collected data, automation of key indicators (emissions, equity, governance), interoperability with existing financial and HR systems, and secure, audited archiving. A CSRD platform centralizes these processes and reduces the administrative burden of controls and audits, especially for bodies with dispersed teams or multiple data sources.

Sector-specific challenges

The main hurdles: limited internal capacity and skills for a complex framework, lack of data harmonization across departments, balancing regulatory obligations with public-interest missions, and the risk of underestimating the reporting scope (subsidiaries, attached operators). Best practice: a pragmatic approach consolidating existing data (carbon footprint, social reports, sustainable procurement policies) then aligning it progressively with the ESRS.
