The Climate Bonds Standard and Certification Scheme is a labelling scheme for bonds and loans. Rigorous scientific criteria ensure that bonds and loans with Certification, are consistent with the 2 degrees Celsius warming limit in the Paris Agreement. The Scheme is used globally by bond issuers, governments, investors and the financial markets to prioritise investments which genuinely contribute to addressing climate change.

Hydrogen Criteria




  1. Climate Bonds Standard V3.0


Timeline of Development:

May 2022: TWG Launch   

Status: The Hydrogen Criteria is currently in development.

Criteria: The Hydrogen Criteria lay out the requirements that Hydrogen production projects must meet to be eligible for inclusion in a Certified Climate Bond and for companies on a credible transition path to issue transition labelled debt

Bonds and loans linked to these eligible assets and projects will be aligned with the Paris Agreement 1.5ºC limit.




Why develop eligibility Criteria for hydrogen investments?

Hydrogen is experiencing unprecedented momentum as a sustainable fuel and feedstock, offering a huge opportunity to replace fossil resources and contribute to the decarbonisation of the economy. Hydrogen production requires high amounts of energy. Most of its production today is based on the cheapest alternatives: natural gas steam reforming and coal gasification. These production pathways have a high carbon footprint, hence making hydrogen production more sustainable is essential to contribute to decarbonisation of the economy

Standards and certification mechanisms will play an essential role in the hydrogen market evolution. Establishing global criteria will foster a level playing field and offer more confidence to investors. Promoting green investments across the whole hydrogen value chain will be essential to develop the hydrogen market.


The Technical and Industry Working Groups (TWG and IWG)

To create the Criteria, we convened a Technical Working Group (TWG) with representatives from academia, public entities, research institutes and international policy bodies from around the world.  These experts ensure a robust pragmatic criteria is developed. Later, an Industry Working Group (IWG) will be convened with industry experts to review the TWG's draft criteria and provide advice.
