EU Taxonomy Regulation Activity evidence packs

Create a separate evidence pack for each economic activity that may be reported as Taxonomy-eligible or Taxonomy-aligned. The Regulation defines an environmentally sustainable activity through a four-part test: substantial contribution to at least one environmental objective, no significant harm to the others, minimum safeguards, and compliance with the applicable technical screening criteria.

The pack should therefore start with the activity mapping and end with the disclosure consequence. A reviewer should be able to see the delegated-act activity description used, the objective assessed, the criteria applied, the facts checked, any limits on the conclusion, and whether the result affects turnover, CapEx, OpEx, GAR/GIR inputs, or only a qualitative explanation.

A useful pack should be short enough to maintain but specific enough to support assurance. It should contain the source citation, the business facts used for the activity mapping, the criterion-by-criterion conclusion, the KPI treatment, and the unresolved questions that prevent or limit alignment.

For non-financial undertakings, Article 8 disclosures are tied to turnover, capital expenditure, and operating expenditure associated with environmentally sustainable activities. The evidence pack should connect operational facts to accounting treatment so finance teams do not have to infer the link at year end.

Do not fill evidence gaps with broad sustainability wording. If the activity is eligible but the team cannot demonstrate substantial contribution, DNSH, minimum safeguards, or a technical screening criterion, the pack should say which condition is unverified and keep the conclusion narrower.

The Taxonomy Regulation recognises that financial market participants may sometimes lack complete, reliable, and timely information for activities outside mandatory reporting. In those cases, complementary assessments and estimates must be limited, prudent, and explained. Apply the same control to internal activity packs: label estimates, identify their source, and separate them from verified evidence.

For reporting from 1 January 2026, an unassessed activity is not automatically an evidence failure. Regulation (EU) 2026/73 allows specified KPI-specific non-materiality options, generally where the cumulative amount is below 10% of the relevant denominator. The pack must record the calculation and keep the amount in the denominator as a separately reported non-material amount; the relief does not convert the activity into eligible, aligned, or non-eligible.

Commission Notice C/2026/2558 explains that an undertaking should assess a material economic activity in its entirety. It should not label one portion of that activity non-material while assessing another portion, because doing so can distort both the eligibility figures and the ratio of aligned to eligible activity. This is Commission guidance on applying the binding amended rules.

A generic compliance checklist is not an activity evidence pack. Taxonomy reporting is activity-specific, criteria-specific, and KPI-sensitive. A pack that does not identify the activity, criteria, evidence, and disclosure impact will not reliably support a public KPI or an investor-facing explanation.

Another mistake is letting public sustainability claims drift away from the evidence record. The same pack should support the claim language, the Article 8 disclosure treatment, and the internal control conclusion, or it should clearly state why one of those uses is not supported.
