On 30 November 2023, Regulation (EU) 2023/2631 of 22 November 2023 on European Green Bonds and optional disclosures for bonds marketed as environmentally sustainable and for sustainability-linked bonds (EuGBs Regulation) was published in the Official Journal of the EU.
The EuGBs Regulation will apply from 21 December 2024, but the market is expected to take it into account sooner. Notably, the recitals highlight that the European Investment Bank will gradually align its green bond programme with the European Green Bond standard.
Understanding the EuGBs Regulation
A lasting positive impact on the environment: the distinctive feature of European Green Bonds
The way the issuance proceeds will be used is the most important feature of a European Green Bond issuance.
Accordingly, any issuer considering issuing a European Green Bond and any investor wishing to subscribe to one should first and foremost enquire about the purpose of the issuance and understand how the proceeds from issuance will be used to attain the sustainable objective.
As per the terms of the EuGBs Regulation, the proceeds of European Green Bonds should be used to finance economic activities that have a lasting positive impact on the environment.
This lasting positive impact can be attained in several ways and the EuGBs Regulation distinguishes between a gradual and a portfolio approach.
Gradual approach
The gradual approach refers to four different methods for assessing the lasting positive impact:
- The principal method is the financing of fixed tangible or fixed intangible assets that are not financial assets, provided the fixed assets relate to economic activities meeting the taxonomy requirements set out in Regulation (EU) 2020/852 of 18 June 2020 on the establishment of a framework to facilitate sustainable investment (Taxonomy Regulation). An example could be the issuance of a European Green Bond to finance the building and functioning of a solar farm meeting the taxonomy requirements.
- Secondly, in a desire to expand to other financial channels, the EuGBs Regulation provides that proceeds of European Green Bonds may also be used to finance financial assets, provided the proceeds of those financial assets are, directly or indirectly through subsequent financial assets, allocated to economic activities that meet the taxonomy requirements.
- Thirdly, proceeds of European Green Bonds may finance the assets and expenditure of households.
- Finally, the proceeds can also finance capital or operating expenditure relating to economic activities that meet the taxonomy requirements or will meet the requirements within a reasonably short period from the issuance of the bond concerned.
Portfolio approach
In addition to the gradual approach, the EuGBs Regulation introduces a portfolio approach enabling issuers to allocate proceeds from one or more outstanding European Green Bonds to a portfolio of fixed assets or financial assets.
The table below summarises the five options for assessing lasting positive impact.

Issuers within scope of the EuGBs Regulation
The EU’s intention is to grant the ability to issue European Green Bonds to a wide spectrum of issuers. Accordingly, European Green Bonds can be issued by financial and non-financial undertakings, as well as non-corporate entities such as sovereigns.
Key aspects of the EuGBs Regulation
Once an issuer has decided to issue a bond subject to the EuGBs Regulation, they must comply with several conditions. The main ones relate to: (i) the role of the external reviewer, (ii) interaction with the Prospectus Regulation, and (iii) publication of information.
External reviewer
Issuers of European Green Bonds should appoint an independent external reviewer who will be responsible for delivering a pre-issuance review of the European Green Bond factsheet and a post-issuance review of the European Green Bond annual allocation reports. The external reviewer should give an independent opinion on the alignment with the taxonomy requirements and thus provide investors with trustworthy information. Ultimately, this should help tackle or at least diminish the greenwashing risks.
Prospectus Regulation
Unlike the initial drafts, the final version of the EuGBs Regulation specifies that, to use the designation “European Green Bond” or “EuGB”, the issuer must publish a prospectus pursuant to Regulation (EU) 2017/1129 of 14 June 2017 on the prospectus to be published when securities are offered to the public or admitted to trading on a regulated market (Prospectus Regulation). In Luxembourg, the competent authority to approve a prospectus is the Commission de Surveillance du Secteur Financier. Any potential issuer contemplating listing and trading their securities will also need to liaise with the Luxembourg Stock Exchange, which is an experienced trading venue in this area. As of October 2023, more than 50 per cent of green bonds worldwide were listed on the Luxembourg Stock Exchange.
Information disclosure
Standardised disclosure is a key focus of the EuGBs Regulation. Adopting the approach taken under other sustainability-linked regulations, the EU authorities are convinced that laying down templates for the disclosure of information will strengthen comparability and make it easier to locate information. Issuers should be able to opt to use public disclosure templates developed by the EU Commission for disclosing relevant information on the allocation of bond proceeds to taxonomy-aligned activity.
Sustainability-linked bonds
Finally, it is worth mentioning that the EuGBs Regulation also covers sustainability-linked bonds. These are defined as bonds whose financial or structural characteristics vary depending on the achievement by the issuer of predefined environmental sustainability objectives.
