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; fostering good governance, integrity and accountability; and addressing obstacles to
a sustainable financial system that lie within market practices, structures and regulation.

             Human rights and environmental supply chain due diligence can be of strategic importance for private
             markets investors, especially given the degree of leverage they have over their portfolio companies.
             Exposure to sustainability risks varies across sourcing regions, industries and manufacturing activities,
    while inadequate due diligence can lead to financial, operational and reputational risks and impacts. An evolving
    regulatory landscape and key human rights and environmental due diligence requirements are shaping
    corporate accountability and investment decision-making.

            diligence on company supply chains can be integrated. From the perspective of investors, this includes
            establishing governance and policies, screening portfolios, undertaking due diligence, establishing
     agreements with investee companies, engagement and monitoring and ensuring supply chain issues are well

                 It is important that portfolio companies understand the specific actions they can take in conducting human
                 rights and environmental due diligence for effective risk management and value creation. Standard and
                 best practices require designing effective due diligence programmes, mapping and screening suppliers,
         assessing risks, training suppliers, monitoring, remediation and disclosure.

The PRI works with its international network of signatories to put the six Principles
for Responsible Investment into practice. Its goals are to understand the investment
implications of environmental, social and governance (ESG) issues and to support
signatories in integrating these issues into 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 six Principles for Responsible Investment are a voluntary and aspirational set of
investment principles that offer a menu of possible actions for incorporating ESG is-
sues into investment practice. The Principles were developed by investors, for inves-
tors. In implementing them, signatories contribute to developing a more sustainable
global financial system.
The United Nations Global Compact is a call to companies everywhere to align their
operations and strategies with ten universally accepted principles in the areas of hu-
man rights, labour, environment and anti-corruption, and to take action in support
of UN goals and issues embodied in the Sustainable Development Goals. The UN
Global Compact is a leadership platform for the development, implementation and
disclosure of responsible corporate practices. Launched in 2000, it is the largest cor-
porate sustainability initiative in the world, with more than 8,800 companies and
4,000 non-business signatories based in over 160 countries, and more than 80 Local
Networks.
