Responsible investment is naturally aligned to private equity through its long-term investment horizon and stewardship-based style.


PRI signatories that are limited partners (LPs) are required to report on their ESG incorporation practices for the three stages of selecting, appointing and monitoring their investment managers. The PRI is building tools to support these practices and create industry-consistent approaches. 

The PRI launched the LP responsible investment due diligence questionnaire in November 2015 and guidance on ESG provisions in fund terms in July 2017, covering ESG considerations in manager selection and appointment.

As a third step, the PRI has appointed ERM to work in partnership with PRI signatories and industry association partners to develop guidance for LPs and General Partners (GP) on how to report on and monitor the ESG integration practices of GPs during the lifetime of the fund. The PRI has formed a working group for this project. The Terms of Reference can be viewed

Long-term infrastructure investors should consider a broad range of possible environmental, social and governance issues that infrastructure investments might face over the course of the assets’ life, in the analysis and assessment of opportunities, and in the ongoing management of investments.


The PRI’s infrastructure work stream launched in February 2017. It supports investors in addressing ESG considerations in private infrastructure equity and debt, and aims to:

  • develop an industry-wide understanding of responsible investment in infrastructure; and
  • promote an industry-wide expectation throughout the infrastructure investment chain that responsible investment is a core part of standard investment practice. 

Upcoming projects

The PRI is building tools to support infrastructure LPs on ESG incorporation practices for selecting infrastructure managers and create industry-consistent approaches. This builds on the PRI’s private equity LP responsible investment due diligence questionnaire, published November 2015, and guidance on ESG provisions in fund terms, published in July 2017.

Event summary: Responsible Investments for Institutional Investors in Hedge Funds (Nov 2017 New York)

A discussion paper on Responsible investment and hedge funds was published in March 2012.  It discusses how to apply the concept of responsible investment to hedge funds.



Themed investing allows investors to address ESG issues by investing in specific solutions to them, such as renewable energy, waste and water management, sustainable forestry and agriculture, health products and inclusive finance.


Case studies: institutional investors’ environmental and social themed investments 

These case studies, published in October 2013, demonstrate how E&S themed investing can form a valuable part of an institutional investors’ approach to responsible investment. Each focuses on a particularly distinctive aspect of the investors’ process or the investments chosen.


Responsible investment in commodities allows investors to address risks such as: labour rights, human rights, land/resource rights, waste, water scarcity and pollution levels in assets, such as forests and agricultural land, and companies throughout the supply chain. Applying responsible investment to investments in commodity derivatives can address systemic issues such as volatile prices and unstable markets.

Principles for Investors in Inclusive Finance

Investors can contribute to economic development and entrepreneurial activity by investing in inclusive finance, but these investments can carry financial and reputational risks. To mitigate such risks, a group of investors launched the Principles for Investors in Inclusive Finance (PIIF) in 2011.

The PIIF are housed within the PRI. In signing the Principles, investors commit to:

1. expanding the range of financial services available to low-income people;

2. integrating client protection into all their policies and practices;

3. treating their investees fairly, with clear and balanced contracts, and dispute resolution procedures;

4. integrating ESG factors into their policies and reporting;

5. promoting transparency in all their operations;

6. pursuing balanced long-term returns that reflect the interests of clients, retail providers and end investors;

7. working together to develop common investor standards on inclusive finance.
