In our last article, we explored how natural resource scarcity quietly rewrites business models.

This time, we’re looking at what happens when the environment stops being a background condition and starts showing up on your financial statements.

Because climate risk isn’t theoretical anymore. It’s an expense line.

The Summer the Servers Failed

In July 2024, Europe recorded its hottest summer in history.

For most people, it meant sleepless nights and overloaded air conditioners.

For one AI infrastructure company, it meant millions in losses.

The company ran large-scale data centres powering generative AI model training. Each server farm consumed enough electricity to power a small town. Cooling systems were designed for efficiency, not endurance.

When temperatures hit 47°C, the system cracked.

• Cooling units maxed out and began shutting down.
• GPU clusters went offline for 72 hours.
• Power usage spiked to 180% of baseline capacity.

Immediate losses: €4.2 million in downtime penalties, service credits, and halted client training runs.‍

Secondary losses: a 15% revenue dip that quarter as customers delayed deployments.‍

Tertiary losses: investor scrutiny, higher insurance premiums, and a reputational mark that followed every due diligence call.

The cause wasn’t poor technology. It was unpriced weather dependency.

The two faces of climate risk

The incident revealed what most ESG frameworks have been saying, but few founders internalize: climate risk isn’t a separate category; it’s operational and financial exposure hiding in plain sight.

It comes in two forms:

• Physical risk is the direct impact from climate events (heatwaves, floods, droughts).
• Transition risk is the indirect impact from policy shifts, market behavior, and regulation during the decarbonization transition.

In this case:

• The physical risk was overheating and grid stress.
• The transition risk was the subsequent spike in electricity prices as carbon taxes and grid prioritization kicked in.

One hit uptime. The other hit profitability.

Together, they turned “weather” into a balance sheet item.

The Heatwave Didn’t Just Cause a Temporary Disruption. It rewrote the company’s financial assumptions.

To prevent a repeat, the company:

• Invested €18 million in renewable-powered microgrids for redundancy.
• Relocated 20% of its data capacity to cooler northern regions.
• Doubled insurance coverage, which also doubled premiums.
• Built a climate risk dashboard for operational monitoring.

Every mitigation measure was necessary and expensive.

Climate volatility had evolved from a background variable to a structural cost.

The CFO later described it bluntly:

“We used to model hardware depreciation. Now we model weather depreciation.”

This isn’t an isolated case.‍

Across industries, extreme weather is forcing companies to revisit how they measure stability.

• Manufacturers are losing production days to floods and droughts.
• Food producers are facing yield volatility as water and soil patterns shift.
• Logistics firms are recalculating delivery routes as ports and roads face climate disruptions.

Every one of these outcomes has a financial signature: higher CAPEX, insurance costs, or revenue volatility.

The story of climate risk is no longer about moral obligation, it’s about financial durability.

How resilient companies are responding

Resilience leaders aren’t waiting for regulation to dictate change. They’re acting because the cost of inaction is already measurable.

They’re:

• Relocating critical operations to low-risk climate zones.
• Diversifying energy portfolios with renewables and on-site generation.
• Integrating ESG, climate, and financial data to simulate exposure.
• Embedding risk scenarios into capital planning, not sustainability reporting.

The smartest companies treat weather like a macroeconomic variable; something to forecast, price, and hedge against.

‍

For fund managers, climate risk is now a proxy for portfolio resilience.

For early-stage investors, climate risk is fast becoming a proxy for portfolio durability.

It’s not just later-stage infrastructure funds that feel it, startups do too. A single heatwave can spike energy costs and shrink runway; a supply-chain disruption can stall production before product-market fit; a policy shift can suddenly make your thesis obsolete.

The next generation of fund managers isn’t running climate stress tests for optics, they’re doing it to protect multiples.

Because as volatility rises, climate resilience is proving to be one of the clearest indicators of founder quality and business model maturity.

‍

Weather used to be unpredictable. Now, it’s predictable in its volatility.

When a heatwave can crash servers and floodwaters can halt production, “environmental” isn’t external anymore, it’s existential.

Climate risk is no longer about sustainability reports.

It’s about whether your business model can survive a summer like 2024.

At Planicorn

We help funds and companies identify and model physical and transition risks by turning climate volatility into actionable foresight. Because in the age of instability, resilience isn’t a value...it’s a valuation.
