What is the PRI?

The PRI is the world’s leading proponent of responsible investment. It works:

  • to understand the investment implications of environmental, social and governance (ESG) factors;
  • to support its international network of investor signatories in incorporating these factors into their investment and ownership decisions.

The PRI acts in the long-term interests:

  • of its signatories;
  • of the financial markets and economies in which they operate;
  • and ultimately of the environment and society as a whole.

The PRI is truly independent. It encourages investors to use responsible investment to enhance returns and better manage risks, but does not operate for its own profit; it engages with global policymakers but is not associated with any government; it is supported by, but not part of, the United Nations.

What are the six Principles for Responsible Investment?

The six Principles for Responsible Investment offer a menu of possible actions for incorporating ESG issues into investment practice.

The Principles were developed by investors, for investors. In implementing them, signatories contribute to developing a more sustainable global financial system. They have attracted a global signatory base representing a majority of the world’s professionally managed investments.

  1. Principle 1: We will incorporate ESG issues into investment analysis and decision-making processes.
  2. Principle 2: We will be active owners and incorporate ESG issues into our ownership policies and practices.
  3. Principle 3: We will seek appropriate disclosure on ESG issues by the entities in which we invest.
  1. Principle 4: We will promote acceptance and implementation of the Principles within the investment industry.
  2. Principle 5: We will work together to enhance our effectiveness in implementing the Principles.
  3. Principle 6: We will each report on our activities and progress towards implementing the Principles.

More on the Principles

What is the PRI’s mission?

“We believe that an economically efficient, sustainable global financial system is a necessity for long-term value creation. Such a system will reward long-term, responsible investment and benefit the environment and society as a whole.

The PRI will work to achieve this sustainable global financial system by encouraging adoption of the Principles and collaboration on their implementation; by fostering good governance, integrity and accountability; and by addressing obstacles to a sustainable financial system that lie within market practices, structures and regulation.”

How did the PRI start?

In early 2005, the then United Nations Secretary-General Kofi Annan invited a group of the world’s largest institutional investors to join a process to develop the Principles for Responsible Investment. A 20-person investor group drawn from institutions in 12 countries was supported by a 70-person group of experts from the investment industry, intergovernmental organisations and civil society.

What is the PRI’s relationship with the United Nations?

The United Nations (UN) has been supporting the Principles for Responsible Investment ever since their launch. The PRI has two UN partners. who play an important role in delivering the PRI’s strategy, including holding a seat each on the PRI Board, and providing additional avenues for signatories to learn, collaborate and take action towards responsible investment.

UN Environment Programme Finance Initiative

UNEP FI is a unique partnership between the United Nations Environment Programme (UNEP)and the global financial sector. UNEP FI works closely with over 200 financial institutions that are signatories to the UNEP FI Statement on Sustainable Development, and a range of partner organisations, to develop and promote linkages between sustainability and financial performance.

Through peer-to-peer networks, research and training, UNEP FI carries out its mission to identify, promote, and realise the adoption of best environmental and sustainability practice at all levels of financial institution operations. 

UN Global Compact 

Launched in 2000, the United Nations Global Compact is a both a policy platform and a practical framework for companies that are committed to sustainability and responsible business practices.

As a multi-stakeholder leadership initiative, it seeks to align business operations and strategies with ten universally accepted principles in the areas of human rights, labour, environment and anti-corruption, and to catalyse actions in support of broader UN goals. With 7,000 corporate signatories in 135 countries, it is the world’s largest voluntary corporate sustainability initiative. 

How is the PRI funded?

The PRI is funded primarily via an annual membership fee payable by all signatories. Additional funding comes from grants from governments, foundations and other international organisations. Corporate sponsorship and in-kind support is sought for standalone events and projects such as the annual PRI in Person conference and major publications/projects.

The PRI’s full financial details are available in the Annual Report.

The PRI Academy

In 2014, PRI launched the PRI Academy with the aim of equipping industry professionals with a common language of ESG, based on the latest thinking in responsible investment. The Academy’s mission is to support industry-wide fluency in ESG and address the well-recognised industry skills-gap in responsible investment, given the significant obstacles these issues present to successful ESG incorporation.

As of 2023, the PRI Academy has trained over 20,000 individuals from 88 different countries.
