TL;DR
New York City pension trustees are conducting a search for asset managers with a focus on climate performance, including those managing current mandates like BlackRock. The Sierra Club welcomes this move, emphasizing the importance of credible climate risk management. The process aims to ensure responsible stewardship and align investments with net-zero goals.
New York City’s pension systems have announced a search for asset managers that will prioritize climate risk management, opening the door for potential changes in major mandates, including those currently held by BlackRock and State Street. This move, announced by NYC Comptroller Mark Levine and the pension trustees, underscores a broader effort to align investment practices with the city’s climate commitments and fiduciary responsibilities.
The search involves identifying asset managers capable of providing passive indexing services with a focus on climate and ESG factors, in line with the city’s investment guidelines. The current contracts for passive index management are set to expire by the end of 2026, prompting a review of existing managers’ climate performance.
Three of the city’s pension systems—NYCERS, TRS, and BERS—have adopted net-zero by 2040 plans and have established climate expectations for their asset managers. Recent reports indicate that most managers are aligned with these goals, though BlackRock remains assessed as insufficiently aligned across all three systems, according to the latest annual climate reports.
Ben Cushing, Director of the Sierra Club’s Sustainable Finance Campaign, highlighted the importance of this process, emphasizing that asset managers must demonstrate credible climate-risk management and responsible stewardship to retain or secure new mandates. He warned that firms failing to meet these standards could lose business, reinforcing the city’s commitment to climate accountability in its investments.
Impact of Climate Standards on Pension Asset Management
This development signals a shift toward integrating climate considerations into the core of public pension investment strategies, potentially influencing how large-scale institutional investors select and evaluate asset managers. It underscores the increasing importance of climate risk management as a fiduciary duty, and could set a precedent for other public pension funds nationwide to adopt similar standards.
By prioritizing managers with credible climate plans, New York City’s pension systems aim to mitigate systemic financial risks associated with climate change, safeguard retirement assets, and demonstrate leadership in sustainable investing. The move also puts pressure on major firms like BlackRock to improve their climate stewardship or risk losing significant business.

Background on NYC Pension Climate Commitments
Since April 2025, NYC pension systems have set standards requiring asset managers to submit net-zero plans, warning that failure to meet these standards could result in losing mandates. The city’s efforts follow a series of actions, including a 2025 review that questioned BlackRock’s climate plans, citing persistent gaps in stewardship and engagement practices.
In November 2025, former NYC Comptroller Brad Lander recommended re-evaluating BlackRock’s role managing billions of dollars due to inadequate climate strategies. The Sierra Club has actively supported these efforts, urging the city to leverage its influence to push for stronger climate accountability among asset managers. Several European pension funds have already divested from BlackRock over similar concerns, highlighting a growing global trend toward climate-conscious investment policies.
“This search is an opportunity to put climate standards into action and enforce responsible stewardship, ensuring firms cannot keep major mandates without credible climate-risk management.”
— Ben Cushing, Sierra Club
