May 2026 has seen record breaking temperatures across the UK and in turn begs the question, how will climate change affect business growth, considering both risks and opportunities?
The current hot spell does not appear to have an official name right now. The UK generally does not formally name heatwaves the way it names storms. Although some reports are linking it to broader climate patterns like a possible strong El Niño influence
The obvious answer is its impact depends on industry, location, supply chains, and how quickly a company adapts.
There are many pathways to consider:
- Physical disruptions slow growth
Extreme weather can damage operations and increase costs:
- Floods, droughts, heatwaves, storms, and wildfires can interrupt production.
- Supply chains become less reliable.
- Infrastructure damage creates repair and insurance costs.
- Employee productivity can decline during heat stress or disasters.
Example: agriculture, manufacturing, logistics, and tourism businesses are especially vulnerable.
- Rising costs reduce profitability
Climate-related expenses can directly affect growth:
- Higher energy and cooling costs
- Increased insurance premiums
- More expensive raw materials
- Compliance and adaptation investments
A business spending more on resilience often has less capital available for expansion.
- Supply chains become more fragile
Global businesses rely on interconnected suppliers. Climate events in one region can affect companies elsewhere:
- Crop failures affect food producers.
- Water shortages disrupt manufacturing.
- Shipping routes can be delayed by storms or low river levels.
A single weak link can slow business growth globally.
- Regulations reshape markets
Governments increasingly introduce:
- Carbon taxes
- Emissions reporting requirements
- Environmental standards
- Sustainability disclosures
Companies that adapt early may gain an advantage, while others face compliance costs and competitive pressure.
- Consumer preferences change
Customers increasingly consider sustainability:
- Demand can shift toward eco-friendly products.
- Brands perceived as environmentally irresponsible may lose trust.
- Younger consumers and investors often prioritise sustainability commitments.
Climate reputation can influence sales and market share.
- Investment and financing change
Investors increasingly assess climate risk:
- Firms with high emissions may face higher borrowing costs.
- Sustainable businesses can attract investment.
- Climate risk now affects valuation and long-term strategy.
Financial institutions increasingly examine environmental resilience.
- New industries and opportunities emerge
Climate change also creates growth markets:
- Renewable energy
- Energy efficiency technology
- Electric transportation
- Climate analytics
- Sustainable agriculture
- Carbon management services
Companies that innovate can find entirely new revenue streams.
Overall, climate change is increasingly becoming a strategic business issue rather than only an environmental one. Businesses that anticipate risks and adapt their products, operations, and investments tend to be better positioned for long-term growth.
