The Rising Importance of Climate Risk in Business

For decades, organisations have planned for the future using one of the world's most dependable assumptions: that tomorrow's climate would broadly resemble yesterday's. Investment decisions, infrastructure design, supply chains, insurance models, and business continuity plans have all been built upon historical climate records. Today, that assumption is becoming increasingly unreliable.

The evidence is difficult to ignore. 2023, 2024, and 2025 were the three hottest years on record, and the UK Met Office forecasts that 2026 is likely to rank among the warmest years ever observed, with global temperatures projected to remain around 1.46°C above pre-industrial levels. As global temperatures continue to rise, the natural systems that regulate our climate are coming under increasing pressure, contributing to more frequent and intense weather extremes and changing environmental conditions.

For businesses, this represents more than an environmental challenge. The changing climate is altering the conditions under which organisations operate. Extreme rainfall, flooding, prolonged heatwaves, droughts, wildfires, and storms are disrupting infrastructure, supply chains, operations, and workforces with increasing frequency. Historical climate records, which have traditionally informed investment decisions and risk assessments, are becoming less reliable indicators of future conditions.

This shift is redefining business risk. Climate hazards are no longer isolated events that can be treated as exceptions; they are becoming increasingly material operational and financial risks that influence asset performance, supply chain resilience, insurance availability, regulatory compliance, and long-term investment decisions. As a result, forward-looking organisations are moving beyond reactive risk management towards climate-informed decision-making, using future climate projections alongside technological innovation and advanced analytics to build resilience in an increasingly uncertain world.

Climate resilience is therefore no longer simply about responding to extreme weather. It is about improving the quality of strategic decisions in a changing climate. Organisations that understand how future climate conditions could affect their operations will be better positioned to protect assets, maintain business continuity, identify new opportunities, and create long-term value in an environment where uncertainty is becoming the new normal.

The Market Is Already Pricing Climate Risk

One of the clearest indicators that climate risk has become a business issue comes not from environmental science, but from financial markets. Insurance providers, lenders, and investors are increasingly incorporating climate-related risks into their decision-making, recognising that the physical impacts of climate change can have direct financial consequences for organisations.

The insurance sector provides perhaps the strongest early warning signal. Insurers rely on detailed risk models to determine where they can provide cover and at what cost. As climate hazards become more frequent and less predictable, those models are changing. Around the world, rising claims from flooding, storms, wildfires, and other extreme weather events are contributing to higher premiums, more restrictive policy terms, and in some regions, reduced insurance availability. In the United States, for example, several major insurers have limited new property insurance policies in parts of California due to increasing wildfire exposure, while homeowners in Florida have experienced substantial premium increases driven by growing hurricane risk.

The UK has not been immune to these pressures. Flooding remains one of the country's most significant climate-related risks, with increasing attention being given to the long-term affordability and availability of insurance in areas exposed to repeated flooding. At the same time, businesses across the UK are facing growing financial pressures associated with weather-related disruption, from property damage and operational downtime to supply chain interruptions and rising recovery costs.

For business leaders, the message is clear: climate risk is no longer a theoretical concern to be addressed only through sustainability reporting. It is already influencing financial decisions, investment planning, and the cost of doing business. Organisations that understand their climate exposure before markets fully price that risk will be better positioned to protect assets, improve resilience, and make more informed strategic decisions. 

Building for Tomorrow's Climate

Many of the buildings, transport networks, utilities, and industrial assets operating today were designed using historical climate records. Engineers and planners have traditionally relied on past weather patterns to determine design standards, maintenance schedules, and expected asset lifetimes. As climate conditions continue to change, those historical assumptions are becoming less reliable, increasing the likelihood that infrastructure will experience conditions beyond those for which it was originally designed.

For organisations making long-term investment decisions, this presents an important challenge. Infrastructure constructed today may remain in operation for 30, 50, or even 100 years. Designing assets based solely on the climate of the past risks creating infrastructure that is increasingly vulnerable over its lifetime. Instead, forward-looking organisations are beginning to incorporate future climate projections into planning, recognising that resilience starts long before an asset is built.

Building resilience does not always require larger or more expensive infrastructure. It often means making better-informed decisions from the outset. This may include considering future flood extents, designing buildings for higher summer temperatures, improving drainage capacity, diversifying water supplies, integrating nature-based solutions, or ensuring critical operations can continue during extreme weather events. Advances in climate modelling, geospatial analysis, and scenario planning are also enabling organisations to better understand how climate risks may evolve over the lifespan of an asset.

Rather than designing for the region’s historic climate, organisations increasingly have the opportunity to build for the future projected climate. Those that incorporate future climate conditions into today's decisions are likely to reduce long-term costs, improve operational reliability, and create assets that remain fit for purpose in a changing world.

When Climate Risks Cascade

One of the greatest misconceptions surrounding climate risk is that it only affects organisations located in areas directly exposed to flooding, wildfires, coastal erosion, or other climate hazards. In reality, climate risk is increasingly transmitted through the interconnected systems that businesses rely upon every day. Supply chains, transport networks, utilities, communications infrastructure, financial markets, and workforce availability all create pathways through which disruption can spread well beyond the location of the original event.

This interconnectedness means that a climate event affecting one region can quickly create operational consequences elsewhere. Drought may reduce agricultural production and increase raw material costs. Low river levels can disrupt major freight routes, as demonstrated during periods of drought on the Rhine, delaying deliveries across European supply chains. Heatwaves can reduce workforce productivity, increase energy demand, and place additional pressure on transport and electricity networks. Even organisations with limited direct exposure to climate hazards may experience delays, increased costs, reduced customer demand, or interruptions to critical services as these impacts ripple through connected systems.

These are known as cascading climate risks: where a single climate event triggers a series of secondary and tertiary consequences across multiple sectors. Rather than occurring in isolation, climate impacts often compound one another, creating disruptions that are larger and more complex than the initial hazard alone. Understanding these relationships is becoming an essential component of modern risk management, shifting the focus from protecting individual assets to strengthening the resilience of the wider systems upon which organisations depend.

Leading organisations are increasingly recognising that resilience extends beyond their own operations. Mapping critical suppliers, understanding infrastructure dependencies, diversifying key resources, and incorporating climate scenarios into business continuity planning all help organisations anticipate where disruptions may originate - not only within their own facilities, but across the broader networks that support them. As climate risks become increasingly interconnected, the organisations best positioned for the future will be those that understand not only the risks they face directly, but also the vulnerabilities embedded within the systems around them.

From Mitigation to Adaptation

Reducing greenhouse gas emissions remains essential to limiting the long-term impacts of climate change. However, many of the physical changes already being experienced will continue to influence the way organisations operate for decades to come.

This means that climate action is no longer solely about reducing emissions. It is also about adapting to a changing operating environment. Alongside decarbonisation, organisations are increasingly investing in resilience: designing infrastructure for future conditions, strengthening supply chains, restoring natural systems, and embedding climate considerations into strategic decision-making. Together, mitigation and adaptation provide the foundation for building organisations that are better prepared for an uncertain future.

Looking Ahead

Climate risk is no longer a distant or emerging issue, but a strategic consideration shaping the decisions organisations make today. From investment planning and infrastructure design to supply chain resilience and corporate governance, the assumptions that have guided business for decades are being challenged by a changing climate.

While the future cannot be predicted with certainty, it can be planned for. Organisations that take a forward-looking approach by understanding their exposure, integrating climate information into decision-making, and investing in resilience will be better equipped to manage uncertainty and identify opportunities as conditions continue to evolve.

Ultimately, resilience is not about predicting every future event. It is about building organisations that can anticipate change, adapt with confidence, and continue to thrive and build resilience in an increasingly uncertain world.
