ECB President Warned Against Diluting CSRD Sustainability Reporting Rules

The European Central Bank (ECB) had raised concerns over proposals to weaken Europe’s sustainability reporting and due diligence requirements. In a letter to European lawmakers, ECB President Christine Lagarde cautioned that reducing the scope of frameworks such as the Corporate Sustainability Reporting Directive (CSRD) and the Corporate Sustainability Due Diligence Directive (CSDDD) could hinder the ECB’s ability to manage climate risks within the financial system.

The warning came as the European Parliament debated the Omnibus I package, which proposed scaling back regulations by raising the CSRD threshold from companies with 250 employees to only those with more than 1,000, excluding nearly 80% of firms from disclosure obligations.

Lawmakers also considered limiting due diligence to direct business partners and requiring less frequent monitoring, while some proposals sought to further narrow the scope to firms with over 3,000 employees and €450 million in revenue.

Lagarde emphasized that the ECB had already integrated climate factors into its monetary policy, including credit risk assessments, collateral frameworks, and the planned introduction of a “climate factor” in 2026. However, she warned that weakening CSRD and CSDDD would restrict access to granular, high-quality climate data, undermining the Eurosystem’s ability to safeguard financial stability against climate-related shocks.

The intervention underscored the importance of robust sustainability reporting as a cornerstone for climate risk management in Europe’s financial system, reinforcing that regulatory rollbacks could have long-term implications for both transparency and resilience.

An ECB warning against CSRD dilution is a strong signal about how financial-stability regulators view sustainability disclosure, and it will influence how far the omnibus simplification actually goes.
