Reviewing our 2023 signatory reporting data, we analysed how infrastructure investors are integrating responsible investment practices across global markets. 

This report analyses data from the 2023 PRI Reporting Framework, focusing on insights from two modules (policy, governance and strategy and infrastructure). The findings highlight the breadth of responsible investment practices among infrastructure investors, but also point to some areas for improvement.

Infrastructure investments are inherently aligned with responsible investment principles due to their exposure to a range of potential environmental, social, and governance (ESG) risks, the potential impact the investments themselves have on ESG factors, and their long-term nature. This is reflected in the depth and breadth of responsible investment policies made by infrastructure investors, and the extent to which investors incorporate such commitments in Limited Partnership Agreements and other such constitutive fund documents.

Infrastructure investments may be particularly exposed to climate-related risks — both physical and transitional — necessitating a proactive approach to sustainability and climate resilience to safeguard asset value and operational continuity. The data suggests that infrastructure investors are taking positive steps in that regard relative to the signatory base as a whole, for example in the use of climate scenarios and metrics. 

Practice on human rights is also more advanced, however there is room for improvement, particularly in relation to the use of the UN Guiding Principles on Business and Human Rights, a baseline for investors to take action on human rights (see Figure 1). The data more generally highlights how infrastructure investors place an emphasis on detailed ESG due diligence and how the findings are integrated into decision making, both pre- and post-investment. This points to the comprehensive way in which ESG risks and opportunities may be managed. However, the data also indicates areas for improvement, notably investors could:

  • Engage more thoroughly and effectively with stakeholders during due diligence; 
  • Make better use of external verification and / or certification tools to support meeting targets on material ESG factors;  
  • Use financial incentives (or penalties) to help build better alignment between investor and asset / portfolio company approaches to ESG.

Notes on the data 

Policy, Governance, and Strategy Module: The data analysed in this module was publicly disclosed by signatories during the 2021 and 2023 reporting cycles. It covers 210 signatories with more than 10% of their assets under management (AUM) in infrastructure. The analysis showed a high correlation between ESG integration and investment performance, although causation cannot be confirmed due to the multi-asset class holdings of the sample. 

Infrastructure Module: The data analysed for this module was publicly disclosed by 159 signatories during the 2023 reporting cycle. The data focuses on signatories with more than 10% AUM in infrastructure. Percentages were calculated based on the number of signatories for whom the indicators were relevant or applicable. Notably, asset owners did not report on asset class modules in 2023, so the analysis is based solely on data from investment managers.
