Article 8 disclosures are linked to undertakings subject to the sustainability-reporting hooks in Articles 19a or 29a of Directive 2013/34/EU, as further specified by the delegated act. That means scope must be read together with the current accounting and CSRD timing rules.
As a practical matter, there are already-reporting entities and later-wave entities. The later waves should be checked against Directive (EU) 2025/794 because that directive deferred certain CSRD entry dates. This is a legal inference from the Accounting Directive hook, not a separate new Taxonomy rule.
