- The CSRD requires banks and insurers to produce standardized ESG reporting (ESRS), including financed emissions and EU Taxonomy alignment.
- Double materiality is central: climate risks on their results and the impact of their financing and underwriting.
- It complements SFDR, the EU Taxonomy and Solvency II/Basel III (no duplication).
- External audit is mandatory; ESG-finance governance and centralized data are essential.
Why the CSRD is crucial for the financial sector
The CSRD requires large companies and mid-sized entities to publish detailed non-financial reports under the ESRS standards. For financial players, this goes beyond transparency: it redefines their role in the sustainable transition. Banks and insurers do not only manage their own impacts; their societal and environmental contribution also flows from the loans, investments and insurance products they provide. Their indirect exposure via portfolios makes double materiality essential.

Companies concerned and timeline
The entities concerned are large European financial institutions and certain regulated mid-sized entities. After the Omnibus I adjustment (February 2026), around 1,000 organizations are in scope in Europe. Implementation is phased: large companies already under the NFRD report first, others follow by size and status. Unlisted financial SMEs are not yet bound but face indirect pressure via ESG data requests from counterparties and regulators.
Reporting requirements and key ESG indicators
Under the CSRD, institutions report ESRS-structured information across the three ESG pillars: environment (exposure to physical and transition climate risks, financed emissions from loan/investment portfolios, sustainable-finance policies), social (financial inclusion, client and staff protection, product accessibility), and governance (ESG risk integration, oversight, remuneration, controls). Quantitative indicators include the portfolio share aligned with the EU Taxonomy, green-asset structure, financed emissions and expected climate-related losses.
Internal organization and collection systems
Compliance requires transforming processes: dedicated sustainability governance with board oversight and finance/risk involvement; centralizing ESG data on a single platform for traceability across subsidiaries and business lines; strengthening internal controls to financial-audit standards; and aligning KPIs on double materiality. A dedicated CSRD platform reduces error risk and eases external audit.
Impacts on products, investment and risk management
Beyond reporting, the CSRD shapes operational strategy. In banking, it drives portfolio reallocation toward Taxonomy-aligned activities; in insurance, it influences climate-risk assessment and underwriting. CSRD data feeds internal pricing, lending and investment models. Transparency on ESG risks becomes a competitive advantage and a resilience factor, supporting responsible investment products and climate insurance.

Interaction with SFDR, the Taxonomy and Solvency II
The CSRD does not replace existing financial regulations; it complements them. SFDR requires disclosing product sustainability, which the CSRD feeds with standardized data. The EU Taxonomy provides the grid to measure activity sustainability, and institutions must disclose their aligned portfolio share. Solvency II and Basel III increasingly factor ESG risks into capital and prudential requirements, reinforced by CSRD data. A rigorous articulation avoids duplicate reporting.
Assurance, controls and best practices
CSRD reports undergo mandatory external audit. Banks and insurers must build an ESG data-control culture comparable to financial data: validation by independent teams (Finance, Internal Audit), full documentation of sources and methods, and external assurance certifying ESRS compliance. Best practices: cross-functional ESG-finance teams, continuous training and automation of documentary production.
