Understanding Physical Climate Risks in Investment Strategies


11/05/2024


Climate-focused investing has historically concentrated on assessing industries’ shifts toward low-carbon practices. This involves examining their adaptation to environmentally friendly regulations, new green technologies, and evolving consumer demands. However, while transition-related risks and opportunities provide one way to gauge climate change’s impact on investments, physical risks and opportunities offer another vital perspective.
 
Recognizing Physical Risks Enhances Evaluation
In 2023, a CDP Worldwide survey reported a 24% increase in companies acknowledging the direct financial impacts of climate change. Nevertheless, physical risks tend to receive less focus compared to transition risks. From 2009 to 2020, for instance, mentions of transition risks in 10-K filings rose from four to 10, while mentions of physical risks only increased from two to four, according to Brookings Institute data. This suggests that businesses are still in the early stages of understanding how physical risks might affect their finances.
 
The reality of physical risks is undeniable, whether through gradual challenges like rising temperatures and sea levels or immediate events like extreme heatwaves and hurricanes. These risks pose substantial financial burdens on businesses and the global economy, often resulting in property damage, lost production capacity, facility closures, and supply chain disruptions, not to mention legal liabilities for failure to make infrastructure resilient.
 
Disasters also impact local communities by affecting employment and displacing residents, which can reduce labor supply and demand for products and services. Over time, these localized effects can accumulate, affecting global productivity, trade, government revenue, and influencing inflation and interest rates.
 
Addressing Physical Risks: Coping and Mitigating
Climate change is a global disruptor with the potential to reshape living, working, and consumption patterns worldwide, affecting nations, industries, and assets at many levels. For instance, population shifts may occur within and between countries as rising temperatures affect agriculture and outdoor labor conditions. Agriculture-dependent areas face particular risks, including food scarcity and increased vulnerability to exploitative practices.
 
Emerging markets are particularly exposed to physical risks, often through flooding or droughts. However, many governments and private entities in these regions are adopting adaptation strategies, such as early warning systems and risk assessments, to mitigate some of this high exposure. Such measures offer a pathway for these countries to manage physical risks and potentially enhance their creditworthiness.
 
Local Data for Global Assessment
While climate change is global, its impacts are often local, as seen with hurricanes in Florida, wildfires in Canada, and flooding in Abu Dhabi. Investors benefit from understanding physical risks at a local level to assess financial damage accurately, even for multinational firms. In the U.S., for example, the Natural Hazards Index developed by AllianceBernstein and the Columbia Climate School maps disaster risks across 75,000 census tracts. Internationally, the Aqueduct Water Risk Atlas helps identify regions with high risks to water availability and quality.
 
A challenge in analyzing physical risks lies in linking them to specific company locations, as companies often don’t uniformly disclose this information. Initiatives like Climate TRACE, which tracks atmospheric carbon emissions, are making strides in identifying high-emission sites and mapping local risk areas for global firms. Additional tools from providers like Moody’s, S&P, and MSCI offer scenario analyses, though their insights sometimes vary, requiring thorough evaluation.
 
Direct engagement with companies can provide valuable insights into their physical risk exposures and resilience strategies. By discussing these issues with company leaders, visiting facilities, and participating in shareholder meetings, investors often gain a clearer understanding than from data alone. A Brazilian bank, for example, faces significant physical risks due to its reliance on agriculture-related loans and crop insurance, as well as potential damage to its branch network from regional flooding and droughts.
 
Physical Risks and Investment Opportunities
The financial toll from extreme weather events increasingly affects both people and assets, highlighting the need for investors to consider opportunities linked to climate adaptation, disaster response, and resilience efforts. With a growing number of data sources, coupled with active investment strategies and company engagement, climate-focused investors can better gauge physical risks and their effects on asset values across regions, sectors, and industries.
