TL;DR
New York City’s pension systems are searching for new asset managers, emphasizing climate risk and ESG factors. The Sierra Club welcomes this move and calls for firms to meet strict climate standards. The process aims to replace or reinforce existing mandates, including those managed by BlackRock and State Street.
New York City’s pension systems have initiated a search for new asset managers, emphasizing climate risk management and responsible stewardship, with the process set to influence major pension mandates currently held by firms like BlackRock and State Street.
On March 26, 2026, New York City Comptroller Mark Levine and trustees of the city’s five public pension funds announced a formal search for passive index asset managers. The aim is to ensure the selected firms align with the pension systems’ climate and ESG standards, particularly as existing contracts are due to expire at the end of 2026. The pension funds, which hold over $127 billion in public equity investments, are seeking managers who demonstrate credible climate-risk management and responsible stewardship practices.
The move follows years of efforts by the city to incorporate climate considerations into its investment decisions. Three of the pension systems—NYCERS, TRS, and BERS—have adopted net-zero by 2040 plans and have set clear expectations for their asset managers’ climate strategies. In recent annual reports, these systems found that most managers were aligned with their climate goals, but BlackRock was assessed as insufficiently aligned across all three systems, raising concerns about its climate stewardship.
The search is part of a broader strategy to enforce climate standards through manager selection, with the city emphasizing that firms must demonstrate credible, transparent plans to retain or win mandates. The process signals a move toward holding asset managers accountable for their climate-related practices and aligns with the city’s leadership in addressing systemic financial risks posed by climate change.
Implications for Pension Fund Climate Leadership
This development underscores a growing trend among public pension funds to prioritize climate risk management in their investment strategies. The move by NYC’s pension systems signals a willingness to enforce stricter standards and potentially phase out managers that do not meet these benchmarks, setting a precedent for other large institutional investors. It also highlights the increasing influence of advocacy groups like the Sierra Club in shaping responsible investment policies, emphasizing that asset managers must demonstrate credible climate stewardship to secure or maintain large mandates.

Background on NYC Pension Climate Commitments
Since April 2025, NYC pension systems have set standards requiring asset managers to submit detailed net-zero plans, with the warning that failure to meet these standards could result in losing mandates. In November 2025, former NYC Comptroller Brad Lander recommended re-evaluating BlackRock’s role due to its inadequate climate plans, which drew public attention to the firm’s stewardship practices. The Sierra Club has actively supported these efforts, urging the city to leverage its influence to improve corporate engagement and proxy voting on climate issues.
While many U.S. pension funds have adopted climate standards, few have imposed tangible consequences for non-compliance. Some European pension funds have already divested from firms like BlackRock over climate concerns, demonstrating a broader shift toward accountability. NYC’s leadership in this area is viewed as a potential model for other public pension systems nationwide.
“We are committed to ensuring our pension investments reflect our climate commitments and fiduciary responsibilities.”
— Mark Levine, NYC Comptroller
