EU Taxonomy Regulation Compliance

Treat eligibility and alignment as separate decisions. Eligibility means the activity appears in the Taxonomy framework for a relevant environmental objective. Alignment requires the activity to satisfy the Taxonomy Regulation's Article 3 conditions: substantial contribution, no significant harm to the other environmental objectives, minimum safeguards, and the applicable technical screening criteria.

The practical compliance file should therefore show the activity description and boundary, the environmental objective, the delegated-act activity reference and version, the screening criteria applied, the assessment date, and the evidence used for each Article 3 condition. A broad statement that the company is "taxonomy compliant" is too imprecise unless it is tied to the activities, reporting period, and KPIs actually assessed.

The EU Taxonomy touches finance, sustainability, business operations, legal, and data owners. Assign each activity one accountable classification owner and one reporting owner, with legal or policy review for ambiguous criteria, minimum safeguards, transitions, and public wording. Set the evidence cut-off and approval date before the annual report is drafted so unresolved activities stay outside aligned numerators.

Non-financial undertakings need reliable turnover, capital expenditure, and operating expenditure inputs for eligible and aligned activities. Financial undertakings need their own delegated-act KPIs and methodologies, including the green asset ratio for credit institutions where applicable. Those differences should be explicit in the workplan instead of being hidden behind a single sustainability-reporting task.

A useful evidence pack lets a reviewer trace the path from source law to activity facts to reported KPI. It should not be a loose folder of sustainability documents; it should be an activity-level record that explains why the activity is eligible, why it is or is not aligned, and how that conclusion affects the disclosed number.

For minimum safeguards, keep the Article 18 analysis separate from environmental technical screening. The Regulation points to procedures aligned with the OECD Guidelines and UN Guiding Principles, including the principles and rights in the eight ILO fundamental conventions referenced by Article 18 and the International Bill of Human Rights. A company should not treat environmental performance evidence as a substitute for this safeguards review.

Check whether an eligible activity has been reported as aligned without evidence for every required condition. Reconcile finance numbers to the activity classification record, including the allocation used for CapEx plans, internal consumption, mixed-use assets, and financial-undertaking KPIs.

A stronger review process asks whether the claim can survive a line-by-line challenge: which activity, which objective, which criteria, which evidence, which KPI, which disclosure period, and which person approved the conclusion.

Regulation (EU) 2026/73 applies from 1 January 2026, although undertakings may use the rules in force on 31 December 2025 for a financial year that started during 2025. It replaced Article 8 templates, changed financial-undertaking denominator rules, introduced optional 10% non-materiality thresholds, and amended specified chemicals DNSH criteria.

For non-financial undertakings, the 10% tests apply separately to turnover and CapEx. OpEx may be omitted in full when it is not material to the business model, provided the denominator is disclosed and the reason is explained; otherwise a separate 10% OpEx option applies. Amounts left unassessed under these options stay in the KPI denominator and are reported separately as non-material.

Until 31 December 2027, a financial undertaking may use the conditional opt-out from most detailed Article 8 rules only if it makes no claim that its activities are associated with Taxonomy-aligned activities and includes the prescribed statement in its management report. The fourth Commission notice explains the amended rules but remains non-binding guidance.

Create one taxonomy assessment record per material activity before drafting public language. The record should contain the activity mapping, source citation, criteria checklist, evidence owner, KPI treatment, review status, and open questions. This keeps the disclosure connected to the same facts used by the people operating the assets, services, loans, investments, or underwriting activity.

When the source material does not clearly support a conclusion, narrow the statement. It is better to report an activity as eligible but not yet aligned, or to flag an unresolved safeguards or DNSH question internally, than to publish an alignment claim that the evidence cannot support.
