European Parliament Plenary Amends Corporate Sustainability Reporting Directive to Tighten Due Diligence and Reporting Requirements

The European Parliament’s plenary session on October 17, 2025, has reshaped corporate sustainability reporting and due diligence rules, aiming to hold companies more accountable for their social and environmental responsibilities. This amendment directly impacts corporations, investors, civil society, and national regulators, likely fuelling debates over balancing business competitiveness with environmental protection and corporate transparency.

The changes are drawn from amendments to the proposal for a directive originally aimed at updating Directives 2006/43/EC, 2013/34/EU, (EU) 2022/2464, and (EU) 2024/1760. These directives relate to sustainability reporting and due diligence within companies operating across the EU. The European Parliament’s plenary, rather than a specialized DG, published the report summarizing the amendments.

This document is an amendment to an ongoing legislative process, expressing concrete policy proposals rather than vague aspirations. It specifies modification of reporting thresholds, scope of companies involved, reinforcement of corporate due diligence obligations, and clearer liability provisions with some proposals manifesting as detailed numerical thresholds and harmonized liability rules.

The policy directions underscore a tension between expanding EU-level harmonized sustainability obligations versus allowing significant national discretion, especially for small and medium-sized enterprises (SMEs). Progressive groups called for wider coverage, strict due diligence, and binding climate plans, whereas conservative factions pushed for higher company size thresholds, national flexibility, and fewer burdens on businesses. Notably, civil liability for failures in due diligence is debated sharply, revealing a cleave between stronger EU enforcement vs. preserving business freedom.

Businesses, especially large corporations and their investors, face increased compliance and potential liability risks. Conversely, civil society and consumers may benefit from enhanced transparency and accountability. National authorities are poised to implement the revised frameworks but may grapple with balancing harmonization against local flexibility. SMEs may see exemptions or lighter standards, reducing immediate impacts on them.

This amendment marks a critical phase in the legislative journey preparing for further trilogues involving the Council and the European Commission. Stakeholders within political groups and member states are expected to vigorously negotiate the next steps, with the European Parliament steering the push towards more robust corporate sustainability legislation.
