Our Take
The consensus is that there's no consensus: even sophisticated asset owners can't bridge the gap between macro climate models and actionable investment decisions.
Why it matters
Pension funds and asset managers are making allocation decisions worth trillions without reliable climate risk frameworks, potentially exposing beneficiaries to unquantified losses from physical and transition risks.

Major asset owners admit climate modeling failures
Senior investment officials from USS Investment Management, KLP, D.A. Carlin & Company and Nuveen told an Ortec Finance panel that integrating climate change into capital market assumptions remains fundamentally broken. The asset owners cited three core problems: fundamental uncertainty in climate outcomes, limited decision-usefulness of long-term scenarios from the Network for Greening the Financial System (NGFS), and a disconnect between top-down climate models and bottom-up asset analysis.
Panelists described a "missing middle link" between macro-level climate modeling and the granular, asset-class-specific insights needed for investment decisions spanning five to ten years. The group found that differences between climate modeling frameworks often exceed the variation between scenarios with different temperature pathways, making it difficult for investment teams to act with confidence.
Physical climate risk has moved from a long-term planning concern to an immediate material risk requiring near-term integration, according to multiple participants. While data coverage and granularity have improved, the inability to quantify extreme weather impacts continues to limit formal integration into capital market assumption frameworks.
Trillion-dollar allocations proceed without reliable frameworks
The admission from sophisticated institutional investors exposes a critical gap in risk management across the asset management industry. These asset owners collectively manage hundreds of billions in pension and endowment assets, yet lack confidence in their climate risk modeling approaches.
The inconsistency between modeling frameworks creates a dangerous situation where investment committees may be making allocation decisions based on flawed or incomparable climate assumptions. This uncertainty has led some participants to abandon fully integrated climate-aware capital market assumptions in favor of shorter-term scenario analysis layered onto traditional stochastic modeling.
The urgency around physical climate risk reflects the growing recognition that extreme weather events are already impacting portfolio performance, not just creating theoretical future risks. Asset owners can no longer treat climate as a distant concern when current weather patterns are affecting real estate values, infrastructure investments, and supply chain exposures today.
Short-term scenarios beat long-term precision
Asset owners should abandon attempts at fully integrated climate-aware capital market assumptions and focus on five-to-ten year scenario analysis that examines energy transition pathways alongside geopolitical and technological developments. This approach acknowledges the fundamental uncertainty in climate outcomes while providing actionable insights for medium-term allocation decisions.
Investment committees need to treat climate uncertainty as comparable to other forms of financial market uncertainty rather than seeking false precision from academic models. This means building multiple plausible scenarios into existing risk management frameworks instead of relying on single-point climate forecasts.
Physical climate risks require immediate integration into investment processes, even where precise quantification remains impossible. Asset owners should prioritize bottom-up assessments using improved data coverage while accepting that extreme weather impacts cannot be fully modeled within traditional risk frameworks.
