If your organization issues or plans to issue green bonds under the European standard, or if you act as an external verifier in this market, the Delegated Regulation (EU) 2026/544 changes the rules of the game. Published on 17 June 2026, this regulation completes the regulatory framework for European Green Bonds (EuGB) established by Regulation (EU) 2023/2631, setting for the first time detailed and binding technical standards for external verifiers.
The message for issuers is clear: it will no longer be enough to hire any entity that calls itself a verifier. From now on, the verifier must demonstrate that it meets concrete criteria of suitability, adequacy and effectiveness. And if it does not meet them, the issuance cannot be labeled as EuGB.
What does this regulation establish?
Delegated Regulation (EU) 2026/544 develops the regulatory technical standards (RTS) that complete the European green bond standard. Its pillars are as follows:
| Regulated area | What is required |
|---|---|
| Suitability, adequacy and effectiveness | Concrete criteria that must be met by the systems, resources and internal procedures of external verifiers |
| Compliance verification function | Definition of how the compliance function must be exercised within the verifier |
| Internal policies and procedures | Minimum standards that verifiers must document and apply in their operations |
| Evaluation methodologies | Criteria on the methods that verifiers must use to analyze bonds |
| Information used in verifications | Standards on the quality, sources and traceability of information used |
| Recognition requests from third countries | Format and content that verifiers from non-EU countries must present to obtain international equivalence |
This regulation does not operate in isolation: it is the technical development of Regulation (EU) 2023/2631, which created the EuGB standard. While that regulation set the general framework, 2026/544 specifies the operational requirements that make its real application possible.
A particularly relevant aspect for the global market is the regulation of recognition requests from third country verifiers. The regulation establishes the exact format and content that these entities must present, facilitating international equivalence and opening the door for verifiers from outside the EU to operate in the European market if they meet the required standards.
Economic and operational impact
This regulation has direct consequences on the costs and operations of two types of actors: external verifiers and EuGB issuers.
- For external verifiers: They will need to invest in adapting their internal systems, documenting their procedures and methodologies in accordance with the new standards, and demonstrating that their resources are adequate. This involves costs of organizational adaptation, possibly internal audits and review of their compliance policies.
- For EuGB issuers: They will only be able to hire verifiers that meet these technical requirements. If the number of enabled verifiers is reduced by the filtering effect of the regulation, supply becomes concentrated and verification prices may rise. The cost of issuing a green bond certified under the EuGB standard will increase to the extent that the verification service is more demanding and, therefore, more expensive.
- For the market as a whole: The regulation seeks to increase the credibility of the EuGB standard against greenwashing. In the medium term, a market with more rigorous verifiers can attract more institutional investment towards European green bonds, which benefits issuers with access to cheaper financing.
As for third country verifiers, the regulation of recognition requests opens a formal pathway to access the European market, which may increase competition and potentially moderate verification prices in the long term.
Who does it affect?
- External verifiers of green bonds: They are directly regulated. They must review and adapt their systems, resources, procedures, compliance policies and evaluation methodologies.
- EuGB issuers: Companies, financial entities, public or supranational bodies that issue or plan to issue bonds under the European green bond standard.
- Capital market financial entities: Banks, asset managers, insurers and other actors that structure, place or invest in EuGB issuances.
- Third country verifiers: Entities outside the EU that wish to obtain recognition to operate as verifiers in the European green bond market.
- Institutional investors in sustainable finance: Investment funds, pension plans and other investors that require the EuGB seal as a selection criterion.
Practical example
Imagine a Spanish energy company that plans to issue a 200 million euro green bond under the EuGB standard to finance renewable energy projects. For that issuance to be labeled as EuGB, it must hire an accredited external verifier.
Before Regulation 2026/544, the criteria for that verifier to be enabled were generic. Now, the verifier must demonstrate in writing that its internal systems are suitable, that its resources are adequate for the volume and complexity of the verification, that it applies evaluation methodologies in accordance with the technical standards set, and that its compliance function is properly structured.
If the chosen verifier does not meet these requirements, the issuance cannot be called EuGB. The issuing company will need to find another enabled verifier, which may delay the issuance process and increase structuring costs. That is why, before starting any EuGB issuance process, it is essential to verify that the verification provider has already adapted its systems to this regulation.
What should companies do now?
- If you are an EuGB issuer or plan to be one: Contact your current or potential external verifiers and request confirmation that they have adapted their systems, procedures and methodologies to Regulation (EU) 2026/544. Do not assume they are enabled.
- If you are an external verifier: Conduct an internal diagnosis to identify gaps between your current operations and the criteria of suitability, adequacy and effectiveness required. Prioritize the documentation of evaluation methodologies and compliance policies.
- If you are a financial entity that structures EuGB issuances: Update your due diligence processes on verifiers to include verification of compliance with Regulation 2026/544 as a prerequisite for any mandate.
- If you are a verifier from a third country: Review the format and content required for recognition requests and assess whether to initiate the accreditation process with the competent European authorities.
- In all cases: Monitor the publication of the entry into force date, which has not been specified in the published text, to plan adaptation timelines with sufficient margin.
Frequently asked questions
What is Delegated Regulation (EU) 2026/544 and why is it relevant to my company?
It is the technical standard that develops the European green bond standard (EuGB), setting the concrete criteria that external verifiers must meet in terms of systems, resources, procedures, methodologies and compliance policies. It is relevant for any company that issues or plans to issue green bonds under the EuGB standard, as it will only be able to hire verifiers that meet these requirements.
What criteria must external verifiers of green bonds meet according to this regulation?
The regulation requires that verifiers demonstrate: suitability, adequacy and effectiveness of their systems, resources and internal procedures; a properly structured compliance verification function; documented internal policies and procedures; evaluation methodologies in accordance with technical standards; and quality standards for information used in verifications.
When does Regulation 2026/544 on green bond verifiers enter into force?
The regulation was published on 17 June 2026, but the entry into force date has not been specified in the published text. It is essential to monitor the EU Official Journal to know the exact timeline for application and plan adaptation with sufficient notice.
Can verifiers from countries outside the EU operate in the European green bond market?
Yes. Regulation 2026/544 expressly regulates the format and content of recognition requests for third country verifiers, establishing a formal pathway for international equivalence. These verifiers must submit a request in accordance with the technical requirements set by the regulation to obtain European recognition.
What happens if an issuer hires a verifier that does not meet the new technical requirements?
If the verifier does not meet the criteria of Regulation 2026/544, the issuance cannot be labeled as a European Green Bond (EuGB) under the standard of Regulation (EU) 2023/2631. This implies the loss of the EuGB seal, with the consequent impact on the marketing of the bond and access to institutional investors that require such certification.
