EU Taxonomy eligibility and alignment.

Why this is harder than it looks

The EU Taxonomy is a classification system, and classification work always sounds simpler than it is. The difficulty is not conceptual. It is that the assessment has to be performed activity by activity, against detailed technical criteria, using financial data that was never structured for the purpose, and the conclusions have to be evidenced.

Most organizations find that their revenue and capital expenditure are not tracked in a way that maps cleanly onto taxonomy activities, which means the first real task is building that mapping and being able to defend it.

The assessment sequence

Eligibility

Identifying which of the organization's economic activities are described in the taxonomy at all. This produces the eligible proportion of turnover, capex, and opex, and requires a defensible mapping from the internal revenue and cost structure onto the taxonomy activity descriptions.

Substantial contribution

For each eligible activity, assessing whether it meets the technical screening criteria for a substantial contribution to one of the environmental objectives. The criteria are specific and often require operational data that finance does not hold, which means involving engineering, facilities, or product teams.

Do no significant harm

Confirming that an activity making a substantial contribution to one objective does not significantly harm any of the others. This is frequently the step where alignment fails, and it is where documentation tends to be weakest because the analysis is performed once and not recorded in detail.

Minimum safeguards

Assessing alignment with the minimum social safeguards, covering human rights, labour, anti-corruption, and taxation. This work usually sits with legal, HR, and compliance rather than with finance, which makes coordination a real part of the effort.

The KPI reporting

The output is three KPIs, expressed as the proportion of turnover, capital expenditure, and operating expenditure associated with taxonomy-aligned activities. Producing them requires:

• A reconciliation from the reported financial statements to the taxonomy denominators, so the figures tie
• An allocation methodology for revenue and costs that span multiple activities, documented and applied consistently
• Treatment of the capex plan, where alignment depends on a forward commitment
• Avoidance of double counting across activities and objectives
• Evidence for each conclusion, retained in a form an assurance provider can test

Making year two cheaper than year one

The first taxonomy assessment is largely analysis. The second should largely be maintenance: the same activity mapping, the same criteria assessments, updated for what actually changed. That only happens if the first year's work is documented as a reusable process rather than delivered as a conclusion. Structuring the assessment so it can be refreshed, rather than repeated, is a deliberate part of the engagement.
