What are climate-related physical risks?

Quick Answer: Climate-related physical risks are the direct financial and operational threats that businesses face from the physical impacts of climate change. They fall into two categories: acute risks (sudden extreme weather events such as floods, wildfires, and hurricanes) and chronic risks (gradual, long-term shifts such as rising sea levels, persistent drought, and increasing average temperatures). Understanding these risks is a prerequisite for credible climate reporting and effective carbon management.

What are climate-related physical risks?

Climate-related physical risks are the tangible, real-world consequences of a changing climate that can damage assets, disrupt operations, and increase costs for businesses. Unlike transition risks, which arise from the shift to a lower-carbon economy, physical risks stem from changes to the physical environment itself.

The distinction matters because the two risk types require different management responses. A business exposed to flooding needs to assess its asset locations and supply chain resilience. A business exposed to transition risk needs to assess its carbon footprint and regulatory exposure. Most organisations face both.

The framework most widely used to categorise these risks comes from the Task Force on Climate-related Financial Disclosures (TCFD), which divides physical risks into two types: acute and chronic.

Acute vs chronic physical risks: what is the difference?

Acute physical risks are event-driven. They arise from a single extreme weather event and can cause immediate, concentrated damage. Examples include:

• Hurricanes and cyclones damaging facilities or disrupting logistics networks
• Flash flooding affecting warehouses, data centres, or retail sites
• Wildfires destroying infrastructure or cutting off supply routes
• Extreme heatwaves reducing workforce productivity or increasing energy demand sharply

Chronic physical risks develop gradually over years or decades. They are harder to attribute to a single event but can be more structurally damaging over time. Examples include:

• Rising sea levels threatening coastal properties and infrastructure
• Sustained increases in average temperature affecting agricultural yields and energy costs
• Persistent drought reducing water availability for manufacturing or food production
• Shifting precipitation patterns disrupting seasonal supply chains

Both types can translate directly into financial losses: higher insurance premiums, asset write-downs, increased operating costs, and reduced revenue from disrupted production or demand shifts.

Why do climate-related physical risks matter for businesses?

Physical risks are no longer a distant concern. The frequency and severity of extreme weather events has increased measurably over recent decades, and the financial consequences are already visible in insurance markets, property valuations, and corporate earnings.

For businesses, the practical implications include:

• Asset exposure: Properties, equipment, and infrastructure located in flood plains, coastal zones, or fire-prone areas face direct damage risk and potential loss of insurability.
• Supply chain disruption: Many physical risks materialise upstream. A supplier affected by drought or flooding can interrupt production even if your own facilities are unaffected.
• Increased operating costs: Higher cooling costs, water scarcity surcharges, and more frequent maintenance requirements all add to the cost base.
• Regulatory and reporting pressure: Frameworks including TCFD, CSRD, and the ISSB's IFRS S2 standard require companies to identify and disclose material physical risks. Investors and lenders increasingly use this information in their decision-making.

For companies with lean sustainability resource, the challenge is knowing where to start. Understanding your carbon footprint is a logical first step: it establishes the baseline data needed to assess where your emissions are concentrated, which in turn points to where your physical risk exposure is likely to be highest.

How do physical risks connect to carbon accounting?

The link between physical risks and carbon accounting is direct. A company's carbon footprint reveals where its emissions are generated across Scope 1, 2, and 3. That same map of activities, suppliers, and geographies is the starting point for a physical risk assessment.

For example, a business with significant Scope 3 emissions from agricultural supply chains is exposed to chronic physical risks from drought and temperature change. A business with energy-intensive operations in coastal locations faces both acute flood risk and chronic sea-level risk.

This is why companies and frameworks increasingly treat carbon accounting and climate risk disclosure as connected processes rather than separate exercises. Frameworks like TCFD and IFRS S2 explicitly require companies to consider how physical risks affect their financial position, and that analysis depends on having accurate, well-structured emissions data to work from.

Seedling's carbon management software produces GHG Protocol-aligned footprints across all three scopes, giving businesses the structured emissions data they need as a foundation for climate risk reporting, whether for TCFD, SECR, B Corp, or investor disclosure purposes.

What does good physical risk disclosure look like?

Good physical risk disclosure goes beyond listing the types of risk a business faces. The TCFD framework, and the ISSB standards that build on it, expect companies to:

1. Identify which physical risks are material to their specific operations, assets, and supply chains
2. Assess the potential financial impact of those risks under different climate scenarios (typically a 1.5°C and a higher-warming pathway)
3. Disclose how those risks are managed and what resilience measures are in place
4. Integrate physical risk considerations into financial planning and capital allocation decisions

Many businesses, particularly those without dedicated sustainability teams, find the scenario analysis element the most demanding. It requires combining emissions data with geographic and climate modelling, and translating the outputs into financial terms that boards and investors can act on.

The starting point for all of this is a credible, well-documented carbon footprint. Without it, identifying which parts of the business are most exposed to physical risk is largely guesswork.

As mandatory climate disclosure requirements expand across the UK and EU, the gap between companies that have built this foundation and those that have not will become increasingly visible to customers, investors, and regulators alike.
