The Escalating Costs of Climate Change for the Insurance Industry

Human-induced climate change is increasingly impacting the insurance industry, driving up weather-related claims and losses at an alarming rate. A comprehensive report by the Insure Our Future network reveals that climate change has accounted for approximately one-third of all weather-related insurance claims filed this century, with the financial burden escalating rapidly. The report estimates that climate-attributed losses totaled between $475 billion and $720 billion between 2002 and 2022, representing a significant portion of the overall weather-related losses incurred during this period. In 2022 alone, climate change was responsible for approximately $52 billion out of a total of $132 billion in weather-related insurance claims, underlining the growing financial impact of climate-related events. This trend highlights the urgent need for insurers and reinsurers to reassess and update their understanding of climate risks to accurately reflect the escalating financial implications of a changing climate.

The report highlights a concerning trend: the increasing proportion of climate-related losses in the overall insurance claims. While climate-related losses accounted for 31% of total weather-related losses in the early 2000s, this figure has risen to 38% in the last decade, indicating a faster growth rate for climate-related claims compared to other weather-related claims. This accelerating pace of climate-related losses emphasizes the need for proactive measures by insurers to mitigate the increasing risks and costs associated with climate change. The financial strain on insurers is further underscored by the finding that the $10.6 billion in climate-attributed losses estimated by 28 major insurers in 2023 nearly matched the $11.3 billion in premiums these same insurers underwrote for corporate fossil fuel clients in the same year. This suggests that the insurance industry is effectively offsetting its climate-related losses by insuring the very activities that contribute significantly to climate change, a practice that raises serious ethical and financial sustainability concerns.

The report criticizes some existing assessments of climate risk, specifically those that focus on future impacts while downplaying the already substantial costs incurred due to climate change. The researchers argue that this perspective, adopted by some reinsurers, fundamentally misunderstands the causal relationship between climate change and current insurance losses. The report contends that climate attribution science, which has developed significantly over the last 15 years, clearly establishes a link between climate change and current extreme weather events and the resulting insurance payouts. By failing to fully integrate this scientific understanding, insurers and regulators risk underestimating the true costs and risks of climate change, leading to inadequate preparedness and responses.

A Call for Action: Reshaping the Insurance Industry’s Role in Climate Change

The report advocates for a proactive and transformative approach by the insurance industry, urging insurers to transition from being part of the problem to becoming part of the solution. This involves moving away from supporting fossil fuel projects and actively contributing to the transition to clean energy. The authors emphasize the historical role of insurance in enhancing societal resilience and call upon the industry to leverage its power to accelerate the transition to renewable energy and align with 1.5°C warming scenarios. This shift requires insurers to stop underwriting new fossil fuel projects, actively invest in renewable energy initiatives, and integrate climate risk considerations into all aspects of their business operations. By adopting such a proactive stance, insurers can contribute to both mitigating climate change and ensuring their own long-term financial stability.

Experts warn that climate change poses an existential threat to the insurance industry. The increasing frequency and severity of extreme weather events are pushing the limits of insurability, forcing governments to intervene and provide coverage in areas where private insurers are withdrawing. This trend creates a dangerous "doom loop" where climate impacts lead to financial instability, hindering the very actions needed to mitigate climate change. To break this cycle, the report emphasizes the urgent need for more resilient systems that can withstand climate shocks and maintain focus on decarbonization efforts even amidst growing instability. This necessitates not only a shift in insurance practices but also a broader systemic change involving governments, businesses, and individuals to collectively address the intertwined challenges of climate change and financial stability.

The Insure Our Future report proposes a seven-point plan for governments to safeguard communities and secure the future of the insurance industry. These actions include integrating climate risks into supervisory frameworks, overseeing insurers’ climate risk management, implementing policies for equitable risk allocation, mandating data transparency on climate-related exposures, requiring scientifically robust climate scenario analysis, and mandating 1.5°C-aligned transition plans for insurers. These measures aim to ensure that insurers accurately assess and manage climate risks, contribute to a just transition, and promote transparency in their operations. Furthermore, the report calls for higher capital requirements for fossil fuel exposure, recognizing the systemic risks posed by continued investments in carbon-intensive industries. By implementing these recommendations, governments can play a crucial role in mitigating climate risks, protecting vulnerable communities, and ensuring the long-term viability of the insurance industry.

The report serves as a wake-up call, highlighting the inextricable link between climate change and the insurance industry’s future. The escalating costs of climate-related losses, the growing dependence on government intervention, and the potential for a destabilizing doom loop emphasize the urgent need for transformative action. By embracing the proposed recommendations, insurers and governments can work collaboratively to mitigate climate risks, build more resilient communities, and ensure a sustainable future for the insurance industry and the planet. The report makes it clear that the time for incremental change is over; bold and decisive action is now required to prevent climate change from overwhelming insurers and economies alike.
