As the world grapples with the escalating impacts of climate change, a new and regressive form of cost-sharing is emerging—insurance risks functioning as a de facto carbon tax. While the idea of a global carbon price has long been championed as a solution to mitigate climate change and redistribute resources equitably, the reality unfolding in 2024 paints a starkly different picture. Rising insurance premiums, driven by the increasing frequency and severity of climate-related disasters, are placing a disproportionate burden on vulnerable populations.
The Insurance Sector: A Canary in the Climate Coal Mine
For decades, natural catastrophe losses were viewed as infrequent, albeit costly, events. However, the past few years have shattered that notion:
- Soaring Losses: From 1993 to 2022, insured losses from natural catastrophes averaged $63 billion annually. Since 2020, this figure has consistently surpassed $100 billion, with Hurricane Milton and European floods pushing 2024 losses to yet another record high.
- Rising Premiums: To offset these losses, insurers have significantly increased premiums. The Guy Carpenter global property catastrophe reinsurance rate index has risen by over 75% since 2017.
While these changes have bolstered insurer profits—U.S. property and casualty insurers like Chubb and Allstate have seen returns of over 140% in five years—they have also created ripple effects that are reshaping communities and economies.
The Hidden Carbon Tax
Insurance costs are becoming a proxy for a carbon tax, albeit one with regressive implications:
- Incentivizing Resilience: Higher premiums could encourage homeowners and builders to adopt more climate-resilient practices, such as constructing homes that are less prone to flooding or wildfires. However, this incentive is undermined by systemic issues, such as Britain’s continued construction of homes in flood zones, with 8% of new houses built in areas highly vulnerable to flooding.
- Exacerbating Inequality: Rising premiums disproportionately affect those least able to afford them. In the U.S., disaster-prone homes are projected to face annual insurance cost increases of $700 by 2053. Many homeowners are already being priced out of coverage, leaving properties uninsured and families vulnerable.
The Bigger Picture: Secondary Events and Systemic Risks
Climate change has transformed the risk landscape for insurers. Once-rare, catastrophic events are now joined by more frequent "secondary events," such as billion-dollar tornadoes and floods. These mid-sized disasters are straining the insurance industry and reshaping markets:
- Market Exits: Some insurers are leaving high-risk regions entirely. In Florida, for instance, the largest property insurer is now state-backed Citizens Property Insurance.
- Uninsured Properties: As premiums rise and private insurers retreat, more properties are left uninsured, increasing the financial burden on governments and taxpayers.
Who Pays the Price?
The implications of these trends are far-reaching:
- For Homeowners: Rising insurance costs may force families to choose between inadequate coverage and financial insecurity. In the worst cases, this could lead to displacement.
- For Governments: Public funds may increasingly be used to bail out disaster-stricken communities, diverting resources from other critical needs.
- For the Planet: Without systemic change, the financial strain of climate disasters will hinder global efforts to invest in renewable energy and climate adaptation.
A Call to Action: Addressing the Root Cause
The rising cost of insurance is a symptom of a larger issue: the failure to adequately address climate change. To break this cycle, we must:
- Accelerate Climate Mitigation Efforts: Governments and corporations must commit to reducing emissions and investing in renewable energy to prevent further warming.
- Enhance Climate Adaptation: Policies should incentivize resilient construction and infrastructure, particularly in high-risk areas.
- Implement Equitable Solutions: A global carbon price, paired with mechanisms to redistribute funds to vulnerable populations, could provide a more just and effective approach to climate financing.
Conclusion: The Urgency of Action
The insurance sector’s struggles offer a sobering glimpse into a future shaped by climate inaction. Without decisive intervention, the costs of climate change will continue to rise, disproportionately impacting those least equipped to bear them.
As we reflect on the challenges of 2024 and look ahead to 2025, one thing is clear: the time for incremental change has passed. It’s time for bold, transformative action to ensure a sustainable and equitable future for all.
