European Parliament Amends Corporate Sustainability Reporting and Due Diligence Rules, Expanding Scope and Harmonisation

The European Parliament has set its sights on reshaping corporate sustainability reporting and due diligence obligations, targeting a wide array of companies with rules that may well stir debate across business, government, and environmental circles. These changes, impacting companies of various sizes and their supply chains, national authorities responsible for enforcement, and civil society keen on corporate accountability, promise to stir both applause and concern from stakeholders balancing regulation and competitiveness.

The changes are sourced from an amendment report dated 17 October 2025, published by the European Parliament plenary session, specifically reflecting intense activity within its committees such as AFET, EMPL, ENVI, and INTA. This document refines the proposal for amending several existing directives (2006/43/EC, 2013/34/EU, (EU) 2022/2464, and (EU) 2024/1760), centralizing on corporate sustainability reporting and due diligence.

This document is an amendment report, proposing concrete modifications to existing EU directives. It contains detailed policy suggestions, including new thresholds for company obligations, clearer harmonisation efforts regarding due diligence requirements and civil liability, and introduces differentiated obligations primarily recognizing SME proportionality. These amendments feature measurable policy orientations but exhibit a spectrum of internal proposals and divergent stances.

The European Parliament’s amendments indicate a clear push towards increasing the ambit and strictness of corporate sustainability rules by lowering company size and turnover thresholds for applying due diligence, expanding reporting to entire value chains, and endorsing EU-wide harmonisation with room for national discretion on enforcement. This shift prioritizes standardisation and accountability yet recognizes proportional burdens for smaller firms, reflecting a tension between deepened EU regulatory powers and national sovereignty, as well as balancing consumer protection and business competitiveness. It also amplifies supervision and transparency in sustainability claims while proposing stricter institutional roles in civil liability.

Businesses, especially large corporations and those deeply engaged in complex supply chains, face an increase in compliance costs and administrative burdens, yet can benefit from clearer, harmonised rules reducing cross-border uncertainty. National authorities will be tasked with enforcement enhancements, potentially increasing operational pressures. Consumers and civil society stand to gain from stronger protections and enhanced transparency regarding corporate sustainability practices, although SMEs may face challenges balancing new obligations despite proportionality clauses.

This document initiates a continuation of the legislative process, signaling ongoing negotiations and likely reactions from the Council and the European Commission. Given the diverse political group amendment activities and contrasting proposals, further deliberation will shape how these provisions finally crystallize into law, with wide implications for governance of corporate sustainability in the EU.
