As the global economy contends with mounting climate-related losses – over USD600 billion in insured damages over the last two decades – the investment case for climate adaptation is gaining strength. From flooded subways in New York and burnt-out neighborhoods in California, to drought-stricken farms in Europe and storm-ravaged coastlines in Japan, major environmental disasters are no longer fodder for movies, and the costs to rebuild are no longer abstract.
In the United States alone, hurricane Milton and Helene in 2024 were amongst the costliest hurricanes in US history, at approximately USD35 billion and USD80 billion in damages respectively, while Canada’s wildfires in 2023 became the most expensive on record for the country, with damages surpassing $1 billion.
The future also holds a sobering reality: insurance claims are likely to rise in regions that were once considered “safe.” In fact, properties along Florida’s eroding shorelines are beginning to lose insurability altogether as entire homes inch closer to the sea with every storm surge. Meanwhile, infrastructure around the world faces the stress of extreme heat, intense rainfall and prolonged droughts, putting pressure on insurers, governments, and private capital to respond.
While mitigation (reducing emissions and overall environmental impact) remains essential, adaptation (making systems more resilient to the physical impacts of climate change) is emerging as an investable trend. For long-term investors, this shift presents an opportunity to capture growth, hedge risk, and align capital with real-world resilience.
Companies that help communities, infrastructure and ecosystems adapt to physical climate risks are unlocking new growth markets while also de-risking their operations and strengthening their long-term resilience. For investors, these businesses represent not only defensive plays but also strategic exposure to rising demand for resilient systems in sectors like water, energy, agriculture and construction.
