External Reviewers of European Green Bonds

External reviewers provide an independent opinion on whether an issuer of European Green Bonds complies with the Taxonomy requirements of the European Green Bonds Regulation. ESMA will be the direct supervisor of external reviewers of European Green Bonds within the EU, under Regulation (EU) 2023/2631 (‘European Green Bonds Regulation’).

To issue a European Green Bond, an issuer must use an external reviewer:

  • before the issuance of a European Green Bond (‘pre-issuance review of European Green Bond factsheet') and;
  • after the full allocation of its proceeds ‘(post-issuance review of allocation report’).
Registration required from 21 June 2026.

ESMA is responsible for the registration and supervision of external reviewers.

Non-EU External reviewers

The Regulation includes a third-country regime for non-EU external reviewers of EU Green Bonds.

The equivalence regime applies to external reviewers established in a non-EU country whose legal and supervisory framework has been recognised as equivalent through a decision adopted by the European Commission.

In the absence of an equivalence decision, an external reviewer with a legal representative established in the European Union, may apply for recognition as long as they comply with the requirements of the EuGB Regulation. Applications for recognition should be prepared and submitted to ESMA in accordance with the regulatory technical standards specifying the information, form and content of applications for recognition of third-country external reviewers in Commission Delegated Regulation C(2026)80 of 12/03/2026, in particular Article 11 and the Annexes thereof.

The endorsement regime is available for external reviewers established in the EU for endorsement of the services provided by a third-country external reviewer, provided that it is able to demonstrate to ESMA on an ongoing basis that the provision of services fulfils requirements which are, at least, as stringent as the requirements of the European Green Bonds Regulation, that it has the necessary expertise to effectively monitor and manage the associated risks and that the services of the third-country external reviewer are used for objective reasons.
