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 and 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 are a voluntary and aspirational set of investment principles that 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.


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

Launch of the PRI at New York Stock Exchange April 2006

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.

The Principles were launched in April 2006 at the New York Stock Exchange. Since then the number of signatories has grown from 100 to over 3000.

The PRI has grown consistently since it began in 2006. For a list of public reporters, total reported AUM per asset class and AUM covered by RI activities please see our signatory information snapshot.

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 – UN Environment Programme Finance Initiative and UN Global Compact – which play an important role in delivering the PRI’s strategy, including by holding a seat each on the PRI Board, and provide additional avenues for signatories to learn, collaborate and take action towards responsible investment.

United Nations Environment Programme Finance Initiative (UNEP FI)
