Assurance has been increasingly proposed as valuable to a number of inter-linked, high-priority areas to the PRI:

  • advancing accountability and transparency;
  • ensuring the credibility of PRI Reporting Framework responses;
  • differentiating leadership;
  • building greater stakeholder confidence.

Assurance working group

The Assurance Working Group launched its work stream in March 2017. The group will help the PRI explore how assurance requirements can contribute to ensuring the credibility of the Reporting Framework responses, differentiating leadership among signatories, and for advancing accountability. The work will culminate in a set of recommendations for how the PRI may introduce assurance requirements for its signatories. The PRI Board will review the recommendations by end of 2017.

March 2017 Establish Assurance Working Group
April-August 2017  Research and develop recommendations 
September 2017  Issue recommendations
September-December 2017  PRI board reviews recommendations 
January 2018  Requirements implemented 


The Assurance Working Group will advise the PRI on possible options to make the PRI Reporting Framework more suitable for assurance. The working group will also advise the PRI on how it may proceed with introducing assurance requirements and/or other confidence-building measures for its signatories. The work will culminate in a set of recommendations issued by the PRI.
