MassPRIM Completes Climate-Risk Review of Investment Managers

The Massachusetts Pension Reserves Investment Management Board (MassPRIM) has concluded a comprehensive review of how its active equity managers assess and incorporate climate-transition risk into their investment decisions. The review, initiated in 2025, examined managers' handling of high-emitting portfolio companies and their integration of climate analysis into investment processes. MassPRIM, which manages approximately $130 billion in pension assets for Massachusetts public employees, plans to use the findings to inform its overall evaluation of manager quality and the selection of new active managers.

The review revealed meaningful differences among managers. Some treat climate-transition risk as a core component of their investment approach, while others are still developing their practices. This disparity underscores the need for asset owners to scrutinize managers' climate competencies, as these risks can materially affect long-term returns.

Sierra Club's Response: A Call for Accountability

In response to the review, Ben Cushing, Director of the Sierra Club's Sustainable Finance Campaign, issued a statement praising MassPRIM's step but emphasizing the need for consequential action. "MassPRIM is taking an important step by making climate-transition risk part of how it evaluates investment managers and selects new ones," Cushing said. "Pension funds should expect the firms entrusted with workers' retirement savings to demonstrate that material climate risks are actually informing their investment decisions and practices."

Cushing stressed that the next step is to make those expectations consequential: "MassPRIM should follow through in manager selection and ongoing oversight, and make clear that managers that fail to meet them can ultimately face consequences for the mandates they manage." This call for accountability reflects a growing trend among asset owners to use their influence to drive climate-risk mitigation in the financial sector.

Local Perspective: Massachusetts Chapter Weighs In

Vick Mohanka, Director of the Sierra Club Massachusetts Chapter, added a local perspective: "Massachusetts should be leading the way in protecting public workers' retirement savings from the growing financial risks of climate change. MassPRIM's approach is an important step toward ensuring that the firms entrusted with workers' money take those risks seriously and are held to a higher standard."

Mohanka's comments highlight the state's progressive stance on climate action and the expectation that public institutions will align their investment practices with broader sustainability goals.

Background: MassPRIM's Manager-Review Process

MassPRIM's review is part of a broader assessment of manager quality, focusing on how public-markets managers address climate-related risks, particularly transition risk. Transition risk refers to the financial risks that companies face as the economy shifts toward a low-carbon future, including regulatory changes, technological disruptions, and market shifts. For high-emitting sectors such as energy, transportation, and manufacturing, these risks can be substantial.

The review's findings will be integrated into MassPRIM's ongoing evaluation of existing managers and its selection process for new mandates. This proactive approach positions MassPRIM as a leader among public pension funds in addressing climate risk.

Implications for Pension Funds and Asset Managers

MassPRIM's move sends a clear signal to asset managers that climate-risk management is no longer optional but a critical factor in securing and retaining pension fund business. As more asset owners adopt similar practices, managers will be incentivized to strengthen their climate-risk frameworks, ultimately benefiting the stability of retirement savings.

The Sierra Club has long called on pension funds and other asset owners to use their relationships with asset managers to strengthen climate-risk mitigation practices, including by incorporating climate standards into manager selection and oversight. This review is a tangible step in that direction.

Looking Ahead: The Future of Climate-Risk Management in Pensions

As climate change continues to pose systemic risks to financial markets, pension funds are increasingly recognizing the importance of integrating climate considerations into their investment processes. MassPRIM's review is a model for other public pension funds seeking to protect beneficiaries' savings while contributing to a more sustainable economy.

The Sierra Club's call for accountability ensures that the review's findings translate into tangible actions. By holding managers to higher standards, MassPRIM can set a precedent for responsible investment practices that prioritize long-term stability over short-term gains.

In the coming years, it will be crucial to monitor how MassPRIM applies the review's findings in its manager selection and oversight. The fund's commitment to transparency and accountability will be key to building trust among stakeholders and ensuring that workers' retirement savings are safeguarded against climate-related financial shocks.
