Insurers' Climate Change Strategies

Climate change poses a significant threat to the insurance industry, with rising temperatures leading to more frequent and severe natural disasters. Insurers are facing mounting losses as a result of increasing claims from policyholders affected by floods, fires, and other climate-related events. The impact of climate change on the insurance sector is twofold: on the asset side of the balance sheet, their investments are exposed to climate risk, particularly in fossil fuel-dependent industries; on the liability side, they face underwriting risk, especially in property and casualty insurance.

In response to these challenges, insurers are taking several actions. Some are incorporating climate risk considerations into their new product launches and underwriting processes, while others have committed to reducing their exposure to carbon-intensive industries. A few insurers are also developing innovative solutions to cover new and frequent hazards, such as parametric pricing or offering risk-engineering and risk-mitigation services. Additionally, insurers are contributing to the public conversation on climate risk, advocating for more aggressive action on climate change, and pushing for policies like fire safety standards and building codes.

However, the insurance industry's response to climate change has been criticized as inadequate by some experts and industry executives. The complex nature of climate risk, involving interconnected global systems and evolving regulatory requirements, poses significant challenges to insurers in managing and mitigating these risks effectively.

Insurers are developing new financial tools, such as catastrophe bonds, to deal with calamities

CAT bonds were first introduced in the 1990s after Hurricane Andrew, which caused $27 billion in damages, of which $15.5 billion was covered by insurance. The hurricane led to the failure of eight insurance companies and pushed others towards insolvency. As a result, insurers re-evaluated their risk exposure and the CAT bond market was born.

CAT bonds are a type of insurance-linked security (ILS) and work as follows: insurers issue bonds through an investment bank, which are then sold to investors. If no catastrophe occurs, the insurer pays a coupon to the investors. However, if a catastrophe does occur, the principal is forgiven and the insurer uses the money to pay their claim-holders. Investors include hedge funds, catastrophe-oriented funds, and asset managers.

CAT bonds are typically used by insurers as an alternative to traditional catastrophe reinsurance. For example, if an insurer is insuring properties in Florida, they might wish to pass on some of the risk so that they can remain solvent after a large hurricane. They could purchase traditional catastrophe reinsurance or sponsor a CAT bond, which would pass the risk on to investors.

CAT bonds can also be adapted to other contexts. For example, Citigroup developed the Stability Note in 2003, which protects the issuer against catastrophic stock market crashes. Professor Lawrence A. Cunningham of George Washington University has also suggested adapting CAT bonds to the risks that large auditing firms face in cases asserting massive securities law damages.

The CAT bond market is growing. In 2023, the issuance of CAT bonds reached a record high of US$15 billion globally, up 8% from 2022. This growth is partly driven by the increasing frequency and severity of natural disasters due to climate change.

Insurers are reducing exposure to carbon-intensive industries

Insurers are reducing their exposure to carbon-intensive industries, with some companies committing to phasing out their stocks in coal companies and declining to offer insurance protection to fossil fuel projects. This is in response to the growing threat of climate change and the recognition that the industry is exposed to climate-related risks on both sides of the balance sheet. As climate change intensifies extreme weather events, insurers are at risk of increasing claims and payouts, threatening their business models and financial stability.

Insurers have a unique role to play in addressing climate change due to their position as risk managers, insurers, and investors. By reducing their exposure to carbon-intensive industries, they are not only mitigating their own risks but also sending a strong signal to other investors and contributing to the transition to a decarbonized economy.

Some insurers have publicly committed to reducing their exposure to carbon-intensive industries by 2030 or 2040. This includes divesting from thermal coal and excluding coal and other fossil fuels from their investment portfolios. These moves are influenced by pressure from activists, investors, and regulators, who are increasingly demanding that the industry addresses climate-related risks.

The pace of change in the insurance industry regarding climate action is slow, and many insurers still have a significant portion of their investments tied to fossil fuel-dependent industries. However, there is a growing understanding among insurers that they need to act quickly to adapt to the threats posed by climate change.

In addition to reducing exposure to carbon-intensive industries, insurers are also developing new products and services to address climate-related risks, such as parametric insurance and catastrophe bonds. They are also advocating for more aggressive international action on climate change and working with governments to develop resilient infrastructure and adaptation measures.

Insurers are contributing to the public conversation on climate risk

Insurers are also collaborating with the public sector to improve building standards and policies. For example, an analysis of risk models may suggest limits to building in flood-prone areas. They are also working with governments to provide affordable coverage and adapt to evolving risks. This is already happening in the United Kingdom, with insurers and the public sector working together to close the protection gap and ensure that insurance remains available and affordable.

Insurers are also advocating for more aggressive action on climate change through policies like carbon prices, which better account for the potential harms from rising temperatures. They are calling for more aggressive international action to curb warming and limit the increase in average global temperatures to 1.5°C.

In addition, insurers are developing new financial tools to deal with major calamities, such as catastrophe bonds for insurance companies. These are high-yield bonds that only pay out if a specified disaster occurs.

In the United States, insurers are also working to incorporate climate change into stress testing scenarios and disclosure requirements. For example, the National Association of Insurance Commissioners (NAIC) has formed a Climate and Resiliency Task Force to evaluate the potential solvency impact of insurers' exposure to climate-related risks.

Insurers are creating innovative products to address climate-related risks

Insurers are developing new solutions to cover newer and more frequent hazards, both acute and chronic. For example, parametric pricing insures policyholders against events of a set magnitude, rather than insuring the value of losses. This shift towards innovative products is essential, as traditional risk transfer methods may no longer be sufficient in the face of escalating climate risks.

Insurers are also exploring ways to protect businesses from the effects of systemic catastrophes, such as heat waves that reduce crop yields, kill livestock, or limit outdoor working hours. Additionally, they are playing a role in matching risk-transfer solutions to alternative capital from investors with a higher risk appetite. For instance, the World Bank convened a group of investors, including a hedge fund and a reinsurance company, to insure a Uruguayan electric power company against drought and high oil prices.

The development of innovative products is a crucial aspect of the insurance industry's response to climate change. By offering these new solutions, insurers can help mitigate the impacts of climate-related risks on individuals, businesses, and the economy as a whole.

Insurers are revising investment strategies to support a sustainable, decarbonized economy

Insurers are facing increasing pressure from regulators, investors, and society to address the impact of climate change on their business models. As the frequency and severity of climate-related disasters continue to rise, insurers are exposed to significant financial risks on both sides of their balance sheets.

In response, insurers are revising their investment strategies to support a sustainable, decarbonized economy. This involves reevaluating investment allocation strategies and systematically evaluating the exposure of their investment and underwriting portfolios to physical climate risk. Insurers are also increasingly considering the environmental impact of their investments and shifting significant portions of their portfolios toward supporting a sustainable, decarbonized economy.

For example, several insurers have committed to reducing their exposure to carbon-intensive industries, such as coal, oil, gas, and utilities, by 2030 or 2040. Some insurers are even phasing out their stocks in coal companies and declining to offer insurance protection to fossil fuel projects. These moves not only help insurers mitigate their own climate risks but also send a strong signal to other investors and contribute to the broader effort to address climate change.

In addition to these voluntary initiatives, insurers are also facing regulatory pressure to align their investment strategies with sustainability and decarbonization goals. For instance, the UK is the first G20 country to require its major banks and insurers to file climate disclosures, and other countries are expected to follow suit. The UN-sponsored Insurance Development Forum has also unveiled initiatives to help developing countries understand and manage physical climate risks, which will further shape the industry's approach to risk management and investment strategies.

The transition to a decarbonized economy is expected to require a massive investment of $100 trillion, and insurers have an opportunity to play a key role in enabling this transition. By revising their investment strategies and supporting sustainable and decarbonized initiatives, insurers can contribute to building a more resilient and sustainable global economy.
