Business continuity on steroids: Risk management for climate change resilience

As the world heats up so, too, do physical risks. Hurricanes are bigger and stronger. Rainfall events are more intense. Drought and wildfires are more prevalent. Climate change has amplified these perils, along with the property damage, business disruption, and workforce stress that can be left in its wake. Global economic losses from natural catastrophe events in 2025 alone were $235 billion.¹ Companies that are not protected against future climate change risk beyond the short-term are likely to incur even more severe climate related damages.

Up until now, much of the discussion on climate change has focused on transition risk: how companies will respond to a changing economy and the shift away from fossil fuels; and moral hazard: how companies contribute to climate change and how they can reduce their relative contribution of greenhouse gases. While this is all well intentioned, the discussion of adaptation and how companies will be impacted by climate change takes a backseat, leaving companies underprepared and lacking information about knowable exposures.

All the while, hospitals near the coast will need to withstand a hurricane with minimal business interruption to continue caring for patients. As thunderstorms intensify, manufacturing, warehouses, and other businesses must be able to safely suppress lightning, which can take out sensitive electronics and manufacturing processes. And operations of all types must protect employees against extreme hot and cold weather events by implementing more reliable air conditioning, heating sources, and extreme weather preparedness plans.

While the discussion of adaptation is important, the most cited environmental issue is operational impact as climate-related events increasingly disrupt business models and supply networks worldwide.² In recent years, summer storms have knocked out power across the American South, closing down pharmacies and grocery stores.³ Last year, Hurricane Helene triggered a nationwide shortage of the country’s supplies of intravenous (fluids) when a production facility in North Carolina went offline.⁴ A 2021 Texas blackout due to heat shut down three major semiconductor plants, impacting production across a number of industries.⁵

To prevent extreme weather-related operational disruptions, organizations need to bolster their business resiliency by understanding—and then addressing—how climate change risks affect long-term business continuity.

Chubb’s Resilience Services can help companies forecast their climate risks, both chronic and acute, and can help identify trends that may emerge during the next 30 years. We help guide the prioritization of investment resources, suggest preventive measures, and help identify what to do in a worst-case scenario. These strategies can help save the family business, protect the hospital from having to evacuate its patients, and aid in business decisions about where to expand and build a new factory.  Chubb helps customers site new development and projects in areas less likely to flood, suffer wildland fire events, and much more.

The goal is to help companies better understand how current and future climate events will impact key locations and their day-to-day business, and help them upgrade construction and enhance preparedness, going beyond minimum building codes, which are based on life safety standards rather than long-term property investment risk.

Climate change models differ from traditional insurance natural catastrophe models at a fundamental level, even if they share some of the same data: Natural catastrophe management models are historical, based on experience by peril. Climate change models are stochastic and forward-looking using various heating scenarios: They forecast the probability of various outcomes under different conditions using a variety of possible global warming realities humanity will face over the next 75 years.

The output of the climate change risk model is a quantification of likely risk—valuable data that needs context and interpretation to be useful. Physical risk consultants, and environmental engineering experts can translate hazard and vulnerability data into a meaningful risk management dialogue. Any climate change product that claims to have an impactful risk management finding purely from a statistical output is not likely actionable or meaningful without risk engineering translation, consultation or dialogue.

Climate change risk models are constantly evolving, and new data is being added in real time. For example, using the latest climate change data around increasing heat over the long term, Chubb is working with clients to discuss heating and air conditioning cost efficiencies and capital expenditure planning implications to equip properties that were built over 20 years ago - when conditions were in fact cooler.

Climate change adds a new dimension to business resilience – the need to consider long-term weather events models when retrofitting existing properties and making decisions about where to locate new ones. Considering the consequences of ignoring possible weather events, it’s a must-have element of any risk management plan.
