The Principles are designed to be industry wide, thus green, social, sustainability or sustainability-linked bond issuers and investors as well as banks are invited to apply for membership. The membership of the Principles is primarily opened to ICMA member firms. For the organisations that are not ICMA members, nor not-for-profit or public sector institutions, an annual financial contribution, the amount of which is set annually by ICMA, is requested for all.
In addition:
- Members must be organisations that have issued, underwritten or placed, or invested in a green, social, sustainability or sustainability-linked bond, or other debt capital market instrument aligned with the Principles, that facilitates and supports environmentally and/or socially sustainable activities.
- Observers can be organisations which are active in the field of sustainable finance but do not qualify as Members, such as but not limited to, NGOs, universities, auditors, consultants and service providers. For more information on the respective role of Members and Observers, please see the Governance Framework.
To be admitted as a Member or as an Observer, an organisation should apply in writing to the Secretariat of the Principles at sustainabilitybonds@icmagroup.org. Applications are subject to approval.
