Why Pension Climate Strategy Is Bigger Than One Tool
When people first start learning about public pensions and climate risk, one of the most common questions is: Why don’t pension funds just divest from fossil fuels?
It’s a fair question. When we see companies contributing to the climate crisis, it makes sense to want retirement savings separated from those harms as clearly and quickly as possible.
But pension governance is more complicated than simply selling one set of stocks and buying another. True governance requires solving the larger economic challenges of the energy transition, not signaling virtue through a portfolio reshuffle. When investors sell shares in a company, those shares are immediately bought by other investors.
Public pension funds are long-term investors with legal obligations to protect the retirement security of workers and retirees and reduce real-world risks. They hold highly diversified portfolios, including slivers of large passive index funds, which means any single fund may own just a small fraction of a company's total shares. When a pension fund sells those shares, they are typically picked up almost immediately by another investor, leaving the company's behavior and capital structure largely unchanged. The signal sent may be meaningful, but the structural impact is limited.
That means pension funds have to think not only about what sends a message, but about what actually reduces systemic risk, creates value, and strengthens long-term financial stability.
One way to understand this is to imagine the economy as a house with a sinking foundation.
The structure is already under strain. Extreme heat affects working conditions. Floods damage transit systems and neighborhoods. Wildfires destroy homes, businesses, and infrastructure. Insurance costs are rising. Entire industries are adjusting to new climate realities. In other words, the house is already shifting under our feet.
A public pension fund does not have everything needed to stabilize that house on its own. But it does have some tools to help stabilize the structure. The important question is, “Which tools actually strengthen the house?”
Divestment can sometimes be like repainting the front door or refreshing the roof trim to boost curb appeal. It changes how the house looks from the street and sends a visible signal about priorities. But cosmetic improvements, however well-intentioned, do not address a sinking foundation. The underlying structural problems remain, and the work to address them still needs to be done. What pension funds can often do more effectively is identify where structural weaknesses are, use the tools they have, and build new ones to reinforce those areas.
That might mean identifying high-emitting companies and climate-vulnerable investments. It might mean pushing companies to adopt credible transition plans. It might mean using proxy voting and shareholder engagement to demand better governance. It might also mean investing in climate resilience and adaptation to help communities and regional economies withstand growing risks.
Those actions are more like placing steel supports under the parts of the house that are sagging. They do not rebuild the entire structure overnight, but they address the underlying problem more directly.
For trustees, this approach also aligns with fiduciary duty. Their responsibility is to act in the best long-term financial interests of beneficiaries, which means understanding where climate risk is showing up, where the fund is exposed, and what tools are available to reduce that exposure while supporting long-term value.
For workers, union leaders, and pension beneficiaries, the takeaway is that pension climate strategy works best when it is grounded in how funds actually operate and in the levers they realistically have.
What an Integrated Approach Can Look Like
Rather than relying on a single tactic, pension funds can use an integrated approach that includes:
Climate risk analysis to identify where the fund is most exposed
Transition planning to evaluate whether portfolio companies are preparing for a lower-carbon economy
Active ownership and proxy voting to influence company behavior and strengthen accountability
Manager oversight to ensure external asset managers and private market general partners are addressing climate-related financial risk
Climate resilience investments in areas like infrastructure, clean energy, and adaptation
Clear governance structures so climate risk is part of investment decision-making, not siloed off to one staff person
For people new to these conversations, that may sound technical, but the core idea is simple: pension funds may not be able to fix the entire house alone, but they do have tools that can strengthen the structure.
And that matters, because these are workers’ retirement savings. They are part of the long-term economic systems our communities depend on. That is why CFA focuses on a combination of investment policies, climate risk analysis, transition planning, active engagement, and exploration of resilience opportunities, an approach grounded in fiduciary duty, shaped by the realities of pension governance, and centered on making public capital work more responsibly over the long term.
