EU Slashes Sustainability Reporting Requirements by Over 70%, Cutting Compliance Costs for European Business

What the Commission Did

The European Commission adopted revised European Sustainability Reporting Standards (ESRS) on July 3, 2026, along with a new voluntary reporting framework for smaller companies outside the current mandatory scope.

The numbers are substantial. According to the Commission, the revised ESRS reduce mandatory datapoints by over 60% and total datapoints by over 70%. The Commission projects that will cut reporting costs by more than 30% per company, consistent with its stated goal of reducing regulatory reporting burdens by 25% across the board.

The standards cover environmental, social, and governance issues: climate change, biodiversity, human rights, and related disclosures that investors and other stakeholders use to assess company risk and impact.

Why the Rollback

The original Corporate Sustainability Reporting Directive (CSRD) was widely criticized by European business groups as an administrative nightmare. The revised ESRS are described by the Commission as "shorter and clearer," with added flexibilities and streamlined processes. The changes draw on technical advice from EFRAG (the European Financial Reporting Advisory Group), stakeholder input gathered in spring 2025, a public consultation in summer 2025, and a "Have Your Say" consultation this spring.

The voluntary standard for smaller companies is designed to solve a specific downstream problem. Large companies subject to the CSRD were demanding sustainability data from their smaller suppliers, effectively imposing compliance burdens on firms that were never in scope. The new voluntary framework establishes a value chain cap: CSRD-covered companies cannot require more information from their supply chain partners than what the voluntary standard covers.

Taxonomy Simplification Running in Parallel

One day earlier, on July 2, Europe's three primary financial regulators each released separate proposals to simplify the EU Taxonomy's disclosure requirements. According to ESG Today, the European Securities and Markets Authority (ESMA), the European Banking Authority (EBA), and the European Insurance and Occupational Pensions Authority (EIOPA), collectively known as the European Supervisory Authorities (ESAs), are responding to a March 2026 Commission request for technical advice on additional simplification.

ESMA's proposals target the operational expenditure (OpEx) KPI, which requires companies to report the share of OpEx tied to Taxonomy-aligned activities. Stakeholders flagged the requirement as complex and burdensome. ESMA proposes limiting the mandatory OpEx KPI to R&D expenditure only, with a voluntary "OpEx+" category covering other items like green procurement.

The EBA's proposals go further in banking. It recommends narrowing or eliminating the Fees & Commissions KPI and the Trading Book KPI, two banking-specific metrics that measure how much advisory income and trading activity aligns with Taxonomy categories. The EBA found those KPIs delivered limited useful information relative to the compliance cost they imposed.

The ESAs also released joint proposals on cross-sector issues, including group reporting and the use of OpEx by financial institutions.

The Strongest Case Against Cutting

Critics of the rollback argue that the CSRD's original scope was not bureaucratic excess but a deliberate policy choice: getting comparable, decision-useful sustainability data across European markets required standardized, mandatory disclosure. Voluntary frameworks consistently produce cherry-picked disclosures. If large financial institutions can no longer require full sustainability data from their value chains, they lose visibility into the actual environmental and social risks embedded in their portfolios. Investors who relied on the CSRD's breadth to make like-for-like comparisons across sectors face reduced comparability.

The Commission's response, embedded in the revised standards, is that quality does not require volume. Shorter, clearer, more consistently enforced standards can theoretically produce more usable data than sprawling frameworks that smaller companies simply cannot execute accurately. Whether that trade-off holds in practice remains unproven.

What Happens Next

Both delegated acts, the one revising the ESRS and the one establishing the voluntary standard, are now transmitted to the European Parliament and the Council of the EU for scrutiny. The standard scrutiny period is two months, extendable by a further two months. The measures take effect only after that period concludes, meaning the earliest possible application is late 2026.

The ESAs' Taxonomy simplification proposals are still in the advisory stage. They were submitted in response to the Commission's March 2026 request, and the Commission retains discretion over which recommendations to adopt and when.

The open question is whether 30%-plus cost savings at the company level will translate into meaningfully better disclosure quality, or whether stripping 70% of datapoints removes information that institutional investors were actually using to price sustainability risk.
