European Green Bond Standard

The European Green Bond Standard is the voluntary EU regime that reserves the EuGB label for bonds meeting taxonomy-linked allocation, disclosure, prospectus and external-review requirements.

What is the European Green Bond Standard?

The European Green Bond Standard is the rulebook in Regulation (EU) 2023/2631 for bonds made available to EU investors under the European Green Bond or EuGB designation. It has applied since 21 December 2024. Issuers choose the label; labelled bonds must meet the Regulation.

Why does the European Green Bond Standard matter to you?

If your company plans an EuGB, finance and operations must link each allocation to an eligible asset or expenditure record. An unsupported taxonomy assessment or incomplete project file can prevent the required pre-issuance reviewer from giving a positive opinion.

How does the European Green Bond Standard work?

Article 4 requires full allocation by maturity under EU Taxonomy requirements. Article 5 allows up to 15% for specified activities without technical screening criteria, subject to its conditions. Complete the Annex I factsheet and obtain a positive external review before issuance. Then prepare an Annex II allocation report for each 12-month period until full allocation. The final report needs external review. After full allocation, publish an Annex III impact report during the bond's life.

What mistakes should you avoid?

  • Using EuGB without meeting Regulation 2023/2631.
  • Treating the 15% flexibility as a waiver of other Article 5 conditions.
  • Reporting one percentage that mixes planned spending with measured environmental results.
  • Failing to retain invoices, approvals, and each allocation's Taxonomy assessment.

Is the European Green Bond Standard mandatory?

No. An issuer can market another green bond without the designation. Once it chooses EuGB, the Regulation's allocation, disclosure, prospectus and review requirements apply.

How is an EuGB different from another green bond?

A green bond may follow voluntary market principles. EuGB is a regulated designation tied to the EU Taxonomy, prescribed templates and external reviews. Neither label proves that the issuer's whole business is green.

Example

Suppose a hypothetical automotive tier-2 parts supplier in Poland issues an EuGB with EUR 20 million of net proceeds. It allocates EUR 17 million to production equipment that meets the applicable Taxonomy requirements and EUR 2 million to an activity for which no technical screening criteria were in force at issuance. Its file shows that the EUR 2 million activity substantially supports a Taxonomy objective, does not seriously harm the others, and meets minimum safeguards and the applicable generic safeguards. EUR 17 million + EUR 2 million = EUR 19 million allocated. EUR 19 million / EUR 20 million = 95%, leaving EUR 1 million, or 5%, unallocated. The Article 5 allocation is EUR 2 million / EUR 20 million = 10%, below the 15% ceiling.

The allocation report must separate the EUR 17 million Taxonomy-aligned allocation from the EUR 2 million Article 5 allocation and explain why the latter qualifies; a 95% headline is not enough. The issuer continues 12-month allocation reporting until full allocation, obtains external review of the report drawn up after full allocation, and publishes at least one impact report during the bond's life.

Green Bonds

A green bond is a bond whose proceeds are reserved for eligible projects with environmental benefits; the label applies to the financing, not automatically to the issuer's whole business.

EU Taxonomy

The EU Taxonomy classifies activities as environmentally sustainable when they support an environmental goal, do not seriously harm the others, follow basic social safeguards, and meet detailed activity rules; Article 8 turns the assessment into company disclosure figures.

Sustainability-linked bond

A sustainability-linked bond is debt whose financial or structural terms change according to whether the issuer meets predefined sustainability performance targets by specified dates.

Greenwashing

Greenwashing is a false or misleading environmental message that makes a product, service, investment, or business appear more beneficial or less harmful to the environment than the evidence supports.
