Signing the internationally-recognised Principles for Responsible Investment allows your organisation to publicly demonstrate its commitment to including environmental, social and governance (ESG) factors in investment decision making and ownership. 

How to apply



Organisations can become a signatory if they fall under one of these three categories:

  • Asset owners representing the holders of long-term retirement savings, insurance and other assets. Examples include pension funds, sovereign wealth funds, foundations, endowments, insurance and reinsurance companies and other financial institutions that manage deposits. This is our principal category of signatory.
  • Investment managers managing or controlling investment funds as a third-party, serving an institutional and/or retail market. Investment managers who are still raising funds, rather than actively managing assets, can sign pre-emptively as provisional signatories.1
  • Service providers  (professional service partners) offering products or services to asset owners and/or investment manager who demonstrate a commitment to providing, developing and promoting services that support a clients’ implementation of the principles.

If you have a query about your organisation’s category, please email us

The PRI Board reserves the right to determine which category is most appropriate.
