European Banking Authority Proposes Simpler ESG Reporting Rules for Smaller Institutions

The European Banking Authority has proposed a major update to its ESG supervisory reporting framework, aiming to make reporting requirements simpler, more proportionate, and easier for banks to manage while still preserving the information supervisors need. The proposed changes are part of a wider EBA simplification package focused on reducing reporting burden across the banking system.

The significance of the proposal lies in its timing. ESG supervisory reporting is still relatively new under the latest EU banking rules, and banks have been preparing for broader sustainability-related reporting obligations since the CRR3 banking package extended ESG risk disclosures beyond only the largest institutions. The EBA is now trying to ensure that the supervisory framework does not become unnecessarily heavy, especially for smaller and less complex banks.

 

Taxonomy reporting is one of the main areas being scaled back

 

One of the most important changes is the removal of several EU Taxonomy-related templates from supervisory reporting, including the requirement for banks to report the Banking Taxonomy Alignment Ratio to supervisors. Those taxonomy disclosures would still remain in Pillar 3 public disclosure requirements, but they would no longer form part of the supervisory reporting package under the proposed revision.

This matters because taxonomy reporting has been one of the more technically demanding parts of sustainability disclosure for financial institutions. By taking several of those templates out of the supervisory reporting layer, the EBA is signaling that not every ESG data point needs to be collected twice through both public disclosure and supervisor-facing channels. That should reduce duplication and lower compliance effort for banks already managing multiple reporting regimes. This interpretation is an inference based on the proposed removal of taxonomy templates from supervisory reporting while keeping them in Pillar 3.

A three-tier system is intended to make reporting more proportionate

 

The proposal introduces a proportionality-based three-tier framework that sets different obligations depending on the size and type of institution. Large institutions with more than €30 billion in assets would report under a fuller ESG framework. Other listed institutions and large subsidiaries would face a more limited set of requirements. Small and non-complex institutions, along with other non-listed institutions, would only have to report a single simplified template on climate-related physical and transition risks.

That is a meaningful change because it recognizes that smaller banks do not have the same balance-sheet complexity, reporting infrastructure, or risk footprint as large banking groups. Rather than applying a single sustainability reporting model across the whole sector, the EBA is moving toward a structure that links reporting depth more closely to scale and complexity. This is likely to be one of the most welcomed parts of the proposal for smaller institutions. This final point is an inference based on the tiered reporting design.

 

Large banks will still face ESG supervision, but in a tighter format

 

For larger institutions, the proposal remains closely aligned with the Pillar 3 ESG disclosure framework, while adding a limited number of supervisory-specific templates. These include templates focused on environment-related corporate exposures and exposure to environmental risks beyond climate. In other words, the EBA is not stepping away from ESG supervision for large banks. It is instead trying to keep the framework narrower and more decision-useful.

This suggests the regulator is aiming for a more targeted supervisory model rather than a broad expansion of sustainability data collection. The goal appears to be better-quality information with less redundancy, rather than simply more reporting volume. That matters because supervisory reporting only works well when the data collected is both relevant and usable. This is an inference based on the narrower set of templates retained for larger banks.

The proposal fits the wider EU push to reduce regulatory burden

 

The EBA’s move sits within a broader EU simplification drive that has already affected sustainability rules through the Omnibus agenda. Banking regulators are now adapting their own reporting frameworks to reflect that direction of travel. The EBA has explicitly positioned the consultation as part of a broader effort to make supervisory reporting simpler, smarter, and more proportionate across Europe.

That broader context is important because it shows the proposal is not an isolated adjustment to ESG rules. It reflects a wider regulatory shift toward trimming duplicated or low-value reporting requirements while retaining core supervisory oversight. For banks, that means ESG reporting is not disappearing, but it may become more focused and somewhat less administratively heavy than initially expected. This interpretation is an inference based on the EBA’s simplification framing and the wider EU regulatory context described in the consultation coverage.

 

What the proposal signals

 

The most important takeaway is that ESG supervisory reporting for banks is being recalibrated rather than rolled back. The EBA is still embedding sustainability risk into prudential supervision, but it is trying to do so in a way that imposes less unnecessary burden, especially on smaller institutions. That makes the proposal significant for both large banks preparing full ESG reporting systems and smaller banks that had been facing a potentially disproportionate compliance load.

If adopted in broadly its current form, the revised framework would make bank ESG reporting more differentiated by size, remove some of the most burdensome taxonomy-related supervisory templates, and create a clearer distinction between public disclosure and supervisory data collection. For the market, that suggests the next phase of banking ESG regulation in Europe may be less about adding more templates and more about making the existing system workable. This final point is an inference based on the structure of the consultation package.
