How Climate Change is Reshaping Risk for Irish Businesses

Climate change is no longer simply an environmental or reputational issue for Irish business; it is a growing financial risk with direct implications for profitability, insurance, investment, and long-term competitiveness. Evidence shows that climate-related disruption is already leading to cost increases across sectors through damaged property, interrupted operations, supply-chain delays, and reduced productivity. These risks are now significant enough to affect commercial planning and capital allocation. For firms in industry, construction, logistics, agriculture, and manufacturing in particular, climate change is becoming a balance-sheet issue because it drives higher recovery costs, greater uncertainty, and more pressure on margins. 

Physical risks

The most immediate exposure is physical risk. Flooding, storms, heat stress, coastal erosion, infrastructure failures, and water disruption can all cause costly business interruption and asset damage. Recent Irish data illustrates how serious this has become. Insurance Ireland reported that Storm Éowyn generated more than €301 million in claims, making it the most expensive storm-related insurance event in Irish history. Although business claims were less than one-third of total claims by volume, they accounted for 55% of the total cost, underlining how expensive climate shocks can be for commercial operators. At the same time, the affordability and availability of flood-related cover is under strain, with protection gaps emerging in higher-risk areas. For business, this means rising premiums, tighter underwriting, and, in some cases, difficulty obtaining suitable cover at all. 

Transition risks

Businesses also face transition risk as Ireland and the wider EU tighten climate policy. These risks include new reporting obligations, shifting customer expectations, carbon costs, technology upgrades, and the need for credible transition plans. The financial consequences of inaction could be very large. A joint report from the Irish Fiscal Advisory Council and the Climate Change Advisory Council estimates that Ireland could face between €8 billion and €26 billion in costs if it fails to meet agreed climate commitments. Even where such penalties fall at state level, the knock-on effects will reach business through taxation, higher energy and compliance costs, delayed infrastructure improvements, and intensified pressure to decarbonise quickly. Companies that postpone adaptation or transition planning may therefore face both direct and indirect financial exposure.  

What are businesses doing? 

A pilot Climate Risk and Resilience Programme carried out in 2025 by Skillnet Climate Ready Academy resulted in almost forty intended actions – which include the education and inclusion of all stakeholders in the importance of integrating resilience, conducting a risk assessment to determine and monitor baseline measurements, seeking input from neighbouring communities, and other strategies that will lead to businesses becoming more front-foot and proactive in their strategies against climate change. Further, businesses are viewing the opportunity to be a leader in the field as a key outcome of transitioning from mitigation to adaptation strategies. 

Conclusion

Climate change in Ireland, as the evidence has suggested, is no longer just an environmental issue. It is having a profound effect on the economy of Ireland and on the costs of the businesses that operate in it. Thus, it is vitally important for businesses to rise to the challenge and incorporate resilient strategies as a proactive measure to combat the associated physical and transition risks, offsetting financial risks in the process. Thus, climate resilience is not only a sustainability goal but a financial strategy: firms that assess risk early, invest in adaptation, and embed climate planning into operations will be better placed to protect assets, maintain continuity, and remain competitive in a more volatile economy.
