The Investment Practices team produce guides, case studies, webinars and events to inform investors how to implement the Principles into their investment practices, in a systematic way, within each asset class.


Asset owners can target long-term returns by incorporating ESG factors in the portfolio and in the selection, appointment and monitoring of managers.


The team is working closely on several fronts to provide responsible investment guidance and implementation support to asset owners. 

Investment strategies - developing practical guidance for asset owners to outline how robust fact-based investment strategies are developed and formulated.

Manager selection, appointment & monitoring - working closely with the Reporting and Assessment team to develop a tool that will provide asset owners with data from the Reporting Framework on investment managers’ responsible investment performance.

Investment policy - developing with signatories practical guidance on how to review existing investment policies to include ESG considerations.


Crafting an investment strategy – a process guidance for asset owners supports asset owners, including their board of trustees and executives, in developing and formulating their investment strategy, and outlines how ESG issues can be incorporated across six steps:

1. Assessment of the investment context

2. Development of mission and vision

3. Development of investment principles (including investment beliefs)

4. Investment strategy selection

5. Implementation

6. Communication

Investment Policy: Process & Practice – A Guide for Asset Owners provides a concise and implementable framework to support asset owners in revising their investment policy in order to incorporate long-term factors in their investment chains. The guidance covers the following aspects: 

  • Reviewing an existing investment strategy
  • Aligning stakeholders
  • Reviewing relevant legislation
  • Reviewing ESG investment guidance, terminology and debate
  • Undertaking a peer review. 

Also, it outlines the most common investment policy sections, including ways to incorporate ESG considerations:  

  • Introduction
  • Definitions
  • Purpose & scope
  • Investment objectives
  • Governance
  • ESG incorporation approaches
  • Active ownership & engagement 
  • Reporting

Aligning expectations – Guidance for asset owners guides signatories on incorporating ESG-factors into manager selection, appointment and monitoring was launched in February 2013.

It discusses:

  • setting expectations on managing ESG factors in a portfolio/fund;
  • including ESG-related expectations in RFPs, questionnaires and discussions;
  • approaches for evaluating potential and appointed managers.

How asset owners can drive responsible investment – Beliefs, strategies & mandates was published by the Policy team in March 2016. It outlines the key role asset owners play in getting ESG considerations incorporated throughout the investment chain. 

Writing a responsible investment policy - Guidance for asset owners, launched in September 2013, discusses responsible investment policy questions.

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. 

Following the launch of the LP responsible investment due diligence questionnaire in November 2015, covering ESG considerations in manager selection, the PRI is working with signatories to develop an appointment tool: guidance for LPs on how to incorporate responsible investment considerations into limited partnership agreements and/or side letters.

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 three standalone tools to support these practices and create industry-consistent approaches.

Following the launch of the LP responsible investment due diligence questionnaire in November 2015, covering ESG considerations in manager selection, the PRI is in the process of finalising and publishing an advisory document for LPs on how to articulate and refine ESG provisions in fund terms in partnership with an appointed PRI signatory working group.

As the third step, the PRI has launched a tender process to appoint an external consultant 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. Information on the tender process is available here. The deadline for applications is 1 March 2017. The PRI is seeking signatories to join a working group that will work in partnership with the consultant. Information on the project and the application process to the working group is available here. The deadline for applications is 28 April 2017.

Integrating ESG in private equity: A guide for general partners (also available in French), case studies supplement (also available in Japanese) and short summary (April 2014) advises GPs to develop a framework for integrating ESG factors into their investment activities, linking this to organisational governance, structure and culture.

Responsible investment can mitigate risk in the typically long-term, project-based world of infrastructure investment. Incorporating ESG considerations into infrastructure investments can consist of including ESG clauses in RFP processes or managing ESG factors to increase exit value.


The PRI is relaunching a work stream on responsible investment in infrastructure to raise awareness on RI in infrastructure, provide industry guidance on incorporating ESG in infrastructure investing, share good practice, and promote investment into low carbon infrastructure. For more information contact

Green Infrastructure Investment Coalition  The aim of the Green Infrastructure Investment Coalition (GIIC) is to connect investors, development banks and advisors to countries seeking finance for green infrastructure developments. The work of the Coalition allows governments and project developers to present their pipeline of projects five years into the future (min. US$100 million deal size) and access new sources of funding from international investors, providing investors with early visibility of future deal-flow and give the opportunity to provide feedback on the structuring of financing instruments.

The GIIC is organised by the PRI, the Climate Bonds Initiative, ICMIF, UNEP Inquiry and LTIIA.


For more information on the GIIC and the PRI’s infrastructure work, watch the webinar: Introducing the Green Infrastructure Investment Coalition (November 2016), including a preview of PRI’s proposed infrastructure strategy.


The case study compendium Responsible investment in infrastructure was published in March 2012.

It provides examples of how investors have incorporated ESG considerations into infrastructure investments.


Though the typically short-term nature of hedge funds makes it challenging to integrate long-term responsible investment, there are many ESG considerations specific to these investment vehicles, including transparency, fund governance and manager pay and incentives.


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.

Responsible Investments for Institutional Investors in Hedge Funds - Event summary


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.
