Taxonomy creates the activity-level environmental test. SFDR uses that data downstream.
That is why so many non-reporters still receive lender and investor Taxonomy questionnaires.

The most useful way to think about Taxonomy and SFDR is as a data chain. A reporting undertaking classifies activities, documents alignment, and publishes Taxonomy outputs. Financial undertakings then consume those outputs in GAR and related metrics. Those financial metrics, in turn, influence portfolio and product sustainability disclosures. If the company-side data pack is poor, the whole chain becomes expensive and inconsistent.
Taxonomy is a classification and KPI system. It decides whether specific economic activities meet environmental conditions and how that is shown in Article 8 disclosures.
SFDR is a disclosure regime for financial-market participants and products. It uses investee and counterparty information, including Taxonomy information, to support broader sustainability disclosures.
Financial undertakings need reliable counterparty data to calculate GAR and related metrics. The Commission has repeatedly noted that financial KPI quality depends on data flows from non-financial undertakings.
That is the direct reason many companies receive requests even when they are not themselves publishing Article 8 disclosures.
A good counterparty data pack is compact, current, and reviewable. It should let the financial institution understand what the numbers mean without asking the company to resend everything from scratch.
The goal is not to publish every evidence file externally. The goal is to make the methodology, perimeter, and confidence level clear enough that the numbers can be used responsibly.
The 2026 simplification act does not remove the data-chain problem. Financial undertakings still depend on counterparties, even if some template burdens are deferred or simplified.
That means company-side discipline still matters. Cleaner company data leads to fewer investor queries, fewer GAR challenges, and less manual rework.
