In September 2018, we began a collaboration with Woods Hole Research Center (WHRC), the world’s leading independent climate research institute, to study the physical effects of climate change on capital markets and asset prices. Our objective is to develop a series of geospatial maps integrating climate science data with financial data. As part of this project, California Public Employees’ Retirement System (“CalPERS”), the largest US public pension fund, is working with Wellington and WHRC to pilot the application of these investment insights.

In many places, more days of extreme heat, longer droughts, or repeated flooding could lead to migration. As people desert intolerable places for more livable ones, asset values will likely fall in the former and rise in the latter. Our goals are to:
The scope of our initiative includes the study of six climate variables: heat, drought, wildfires, floods, hurricanes, and water availability. Each of the six variables — and combinations thereof — pose different degrees of risk to different regions and asset types.
Our approach, which we call integrated spatial finance, is the visual plotting of capital-market variables over climate variables on a series of global maps. Collaborating with WHRC facilitates our ability to integrate fundamental insights into climate science and enables us to better analyze and question them, and to draw practical, action-oriented conclusions.
High-level summary of our process
Insights from our maps are allowing our investors to compare relative valuations and better engage with executive teams. We are encouraging investors to focus on location as a key input into their process. Sectors with significant dependence on fixed locations, such as real estate, mortgages, municipal bonds, insurance, utilities, infrastructure, and agriculture may be the most negatively affected. Sectors with more moveable assets may be better off.
For entities like CalPERS with very long-term liabilities, climate change presents a significant strategic challenge. For society, transparency about climate issues and the repricing of assets can help improve planning for local and federal governments on issues like infrastructure and migration.
We believe capital market participants must manage a variety of risks, including those related to climate change. We hope our work will inspire others to rethink asset class and geographic exposures to better account for physical climate risks. We hope to drive discussions that incentivize longer-term performance measurement to better align climate time horizons with investor time horizons. In our mind, these types of shifts in thinking should be required of forward-looking fiduciaries. They may also help provide better transparency, lead to more gradual asset repricing, and advance and inform public discourse.
