ESMA proposes simpler EU Taxonomy reporting
AI Analysis
ESMA submitted technical advice to the European Commission on 29 October 2026 proposing targeted simplifications to the EU Taxonomy Disclosures Delegated Act. The advice would narrow the mandatory OpEx KPI to non-capitalised R&D expenditure, remove the weighted-average group KPI and simplify several undertaking, group and asset-manager disclosures, but it is not itself binding; the existing rules continue to apply unless and until the Commission amends the Delegated Act.
Key dates
- 2026-03-04
- The European Commission issued its call for technical advice to the European Supervisory Authorities on targeted simplification of the Taxonomy Disclosures Delegated Act.
- 2026-07-01
- ESMA launched its consultation on selected Taxonomy KPIs and proposed simplification measures.
- 2026-08-12 Deadline
- ESMA’s consultation period closed.
- 2026-10-29
- ESMA submitted its Final Report and technical advice to the European Commission for consideration in the review of the Taxonomy Disclosures Delegated Act.
Suggested considerations
- Compliance teams should continue applying the currently effective Taxonomy Regulation and Taxonomy Disclosures Delegated Act until any Commission amendment enters into force.
- Firms should monitor the Commission’s review of the Disclosures Delegated Act and assess any subsequent delegated act, scrutiny period, entry-into-force date and transitional provisions before changing reporting controls.
- Corporate reporting teams may wish to model the effect of an R&D-only mandatory OpEx KPI, including the IAS 38 or national-GAAP population, numerator mapping and interaction with existing materiality reliefs.
- Groups should inventory parent and subsidiary business lines, assess whether secondary businesses could exceed a cumulative 10% consolidated-turnover threshold, and prepare for possible parent-regime and simplified secondary-business templates.
- Asset managers and other financial undertakings should avoid treating the proposed absence of voluntary OpEx reporting as current law and should document the basis for any voluntary Taxonomy metrics under existing disclosure and anti-greenwashing controls.
- Issuers and sustainability-reporting teams should review sustainable-bond, internal-sales, contextual-information and CapEx Type C data processes so they can adapt if the Commission adopts ESMA’s recommendations.
- Reporting governance should track whether any future voluntary alternative metric is reconciled to the mandatory KPI and subject to applicable ESMA Guidelines on Alternative Performance Measures.
What changed
ESMA recommends that the mandatory Article 8 Taxonomy Regulation OpEx KPI focus on non-capitalised R&D expenditure, with the denominator based on expenditure recognised under IAS 38 or relevant national GAAP and the numerator drawn from the existing Annex I categories. It does not recommend introducing a mandatory voluntary OpEx+ metric, and advises against allowing financial undertakings, including asset managers, to use an OpEx KPI voluntarily for Taxonomy disclosures. For groups, ESMA recommends removing the weighted-average KPI and using the parent undertaking’s applicable reporting regime as the main regime, with additional simplified disclosures for material secondary businesses; a cumulative 10% consolidated-turnover threshold is identified as a possible omission threshold for secon
Compliance impact
The immediate legal impact is limited because ESMA’s final report is technical advice rather than a binding amendment, and the Commission has not yet adopted revised disclosure rules. The practical impact could be material for Taxonomy reporting architecture, group consolidation, KPI data lineage and sustainability-reporting controls if the Commission adopts the recommendations; market commentary
