On 7 November 2025, the European Commission published a call for evidence on proposals to amend the European Union’s Taxonomy legislation. In particular, the call is in relation to two delegated regulations amending the Taxonomy Climate Delegated Act ((EU) 2021/2139, the “Taxonomy Climate Delegated Act”) and the Taxonomy Environmental Delegated Act ((EU) 2023/2486, the “Taxonomy Environmental Delegated Act”) (the “Call for Evidence”). The document is accessible via Commission webpages relating to the Taxonomy Climate Delegated Act and the Taxonomy Environmental Delegated Act.
Political context
The Call for Evidence sits within the European Commission’s broader simplification agenda to cut red tape and reflects the commitment to reduce reporting burdens for companies and support sustainable finance through clearer and more proportionate rules. It also responds to the Commission’s obligation under the EU Taxonomy Regulation (Regulation (EU) 2020/852) to regularly review and, where appropriate, amend the technical screening criteria.
Aim of initiative
The European Commission has noted that experience from the initial application indicates that some technical screening criteria in the Taxonomy Climate Delegated Act and the Taxonomy Environmental Delegated Act have proved complex or difficult to evidence in practice.
The European Commission is therefore of the view that, without EU-level intervention, these issues are likely to persist or intensify; the risk is not only administrative — if the framework is seen as impractical or insufficiently robust, it could, in their view, undermine confidence in the EU’s wider sustainable-finance agenda.
The European Commission is therefore collecting further evidence through targeted consultations, feedback to this Call for Evidence and continued engagement with stakeholders involved in the day-to-day application of the EU Taxonomy Regulation.
Next steps
The deadline for providing comments is 5 December 2025, so there is only a short window to have your say. The feedback provided will then feed into the revision of the Taxonomy Climate Delegated Act and Taxonomy Environmental Delegated Act.
