The Internal Operations teams ensure that the PRI is sufficiently and responsibly resourced to do its work servicing signatories and ultimately serving their beneficiaries.


The Human Resources team works to attract, retain and develop the required human capital.

The PRI aims to be a genuinely inclusive organisation. Our objective is to integrate equal treatment and promotion of diversity into all aspects of the PRI’s day-to-day life.

The PRI commits to:

  • ensuring that all individuals who come into contact with the PRI, whether as employees, contractors, consultants, signatories or in other capacities, are treated with dignity and respect;
  • ensuring that the opportunities the PRI provides for learning, personal development and employment are made available on a non-discriminatory basis;
  • providing a safe, supportive and welcoming environment for colleagues and visitors alike.

The Operations and Finance teams work to build a financially sustainable organisation, and to provide the infrastructure required to enhance transparency of, and collaboration amongst, signatories.

The PRI website combines public outreach with signatory-only tools such as the Collaboration Portal and the Reporting Framework. Rich personalisation features allow users to build a profile of their interests and receive a homepage and e-newsletters that are tailored to them.
