• EU advisers call for integrated ESRS and Taxonomy reporting to reduce duplication and compliance costs for corporates
• Proposed changes aim to align ESRS with SFDR and Benchmark Regulation, tightening consistency across EU sustainable finance rules
• Commission to adopt revised ESRS via Delegated Act before summer 2026, shaping next phase of CSRD implementation

Brussels Moves to Refine Europe’s ESG Reporting Backbone

Brussels is entering a critical phase in reshaping its corporate sustainability reporting regime, as the Platform on Sustainable Finance delivers targeted recommendations to improve the usability and coherence of the European sustainability reporting standards.

The advisory body, which supports the European Commission on sustainable finance policy, has assessed technical advice prepared by the European Financial Reporting Advisory Group on amendments to the ESRS. Its response focuses on reducing complexity for companies while strengthening alignment across the EU’s expanding regulatory architecture.

The intervention comes as the Commission prepares a Delegated Act to revise the first set of ESRS under the Corporate Sustainability Reporting Directive, with adoption expected before summer 2026.

Bridging ESRS and the EU Taxonomy

A central concern raised by the Platform is the fragmentation between ESRS disclosures and the EU Taxonomy Regulation. Companies currently face overlapping reporting requirements, particularly across environmental objectives and minimum safeguards.

To address this, the Platform recommends a joint mapping exercise between itself and EFRAG. The goal is to enable companies to use a single set of datapoints across both frameworks, supported by clearer implementation guidance.

This approach would allow overlapping ESRS datapoints to serve dual purposes, creating a unified reporting and assurance process. For corporates, this translates into lower administrative burden and improved clarity in how sustainability performance is measured and verified.

The Platform states: “The objective is to reduce duplication by enabling overlapping ESRS datapoints – across environmental objectives and minimum safeguards – to be used for both frameworks through a single, integrated reporting and assurance process.”

Embedding Taxonomy Metrics Into Transition Plans

Another priority is strengthening the link between taxonomy metrics and corporate transition planning. The Platform calls for deeper integration of taxonomy-aligned revenues, capital expenditure, CapEx plans, and, where relevant, operating expenditure into ESRS climate transition plan disclosures.

This would extend beyond climate to other environmental transition disclosures where applicable, ensuring that financial flows and sustainability strategies are more tightly connected.

For investors and regulators, this integration improves visibility into how capital allocation aligns with EU climate objectives. For companies, it clarifies expectations on how transition plans should be quantified and disclosed.

Standardising Transition Plans and Improving Consistency

The Platform also recommends developing a voluntary standardised template for transition plans within ESRS reporting. This would provide non-financial undertakings with a clearer structure for disclosing decarbonisation pathways and environmental strategies.

At the same time, it calls for improved consistency between ESRS, the Sustainable Finance Disclosure Regulation and the Benchmark Regulation. Differences in definitions, scope, and methodologies across these frameworks have created friction for both issuers and financial market participants.

Harmonisation would strengthen the integrity of the EU’s sustainable finance ecosystem, ensuring that corporate disclosures, investor reporting, and benchmark construction operate on a common foundation.

What Executives and Investors Should Watch

For C-suite leaders and investors, the proposed revisions signal a shift toward consolidation rather than expansion of reporting requirements. The emphasis is on interoperability, usability, and decision-useful data.

Companies preparing for CSRD compliance should anticipate more integrated reporting expectations, particularly around taxonomy alignment and transition planning. Early alignment of internal data systems with both ESRS and taxonomy metrics will be critical.

Investors, meanwhile, stand to benefit from more consistent and comparable disclosures, improving the reliability of ESG data used in capital allocation and risk assessment.

A Defining Moment for EU Sustainable Finance

The Commission’s upcoming Delegated Act will determine how effectively Europe can streamline its sustainability reporting framework without diluting ambition.

By tightening alignment across ESRS, the EU Taxonomy, SFDR, and related regulations, Brussels is attempting to balance regulatory depth with operational practicality. The outcome will shape not only corporate reporting across Europe but also the credibility of the EU’s broader sustainable finance agenda in global markets.
