Climate change, which started as a scientific theory and became the subject of environmental policies and international negotiations, refers to long-term changes in the Earth's climate. [1] Climate change poses some significant economic risks due to changing weather patterns, extreme weather events and rising sea levels.
Transferring risk to global reinsurance and capital markets may be one of the solutions. [3] There is the question of who will bear the cost of damage caused by extreme weather, which is a concern for both companies and governments of developed and developing countries. An important question that arises given this challenging situation is how to reduce the risk of experiencing these losses. [4] The insurance industry is particularly vulnerable to the effects of climate change because natural disasters can lead to large losses and claims. Insurance premiums are based on the costs that the insurer predicts to cover a risk, and this function of insurance promotes the reduction of losses by private individuals. [5]
As natural disasters become more frequent and more costly, insurance companies face major challenges. Climate change is predicted to have a significant impact on the financial services industry, including insurance, but it is currently unclear what the specific impacts will be and how well the industry is prepared to respond to them. But it is certain that insurers will need to make some changes to mitigate the loss. It is difficult to fully understand the extent and severity of the problem, in part due to the lack of sufficient data on the extent to which insurers are exposed to climate change-related risks. [6]
Climate change causes unpredictable changes in the frequency, intensity, scope and duration of extreme weather events, which in turn affects the probability distributions used by the reinsurance industry. [7]
According to the IPCC, human activities are believed to have an impact on extreme weather conditions, including greenhouse gas levels. Linking human activities to changes in tropical cyclones is difficult because records are unreliable, there is a high degree of variability, and scientists do not fully understand the effects of climate change on tropical cyclones. Some extreme weather events are caused by natural variability, while others are caused by a combination of natural events unrelated to human activities. [8]
The insurance industry is used to dealing with uncertainty by incorporating risk assessments into premiums. Climate change adds to this complexity and creates additional challenges, but it also offers potential new opportunities for (re)insurers and governments. [9] Insurers typically assume significant risks, but they often manage them through underwriting and diversification of their investments, as well as reinsurance. This is a type of insurance for insurance companies and helps prevent any company from taking too many risks that could jeopardize its financial stability. [10]
Impacts of climate change, such as more severe hurricanes and more frequent wildfires after droughts, can affect the legal framework. [11] Climate change can significantly increase the risks that the insurance industry is exposed to, and the insurance industry will need to develop new policies in this direction. A key challenge is to prevent insurers from assuming new risks by using premiums from new policies to offset old risks. [12]
Risk assessment and risk management are essential components of effective adaptation, which includes both prevention and transfer of risks. [13] They help identify and assess potential risks and hazards that may be caused or exacerbated by climate change. This information can then be used to develop strategies to prevent or mitigate these risks and to communicate or mitigate the potential impacts of these risks should they materialise.
Risk assessment is the process of identifying and evaluating potential risks and hazards and determining the likelihood of their occurrence. [14] This information can be used to prioritize the most important risks and develop strategies to address them. On the other hand, risk management is the process of implementing strategies to prevent or mitigate risks and to transfer or mitigate the potential effects of risks if they materialize. This may include strategies such as building seawalls to protect against coastal flooding or developing early warning systems to alert communities to potential hazards.
This is the foundation of a functioning insurance industry. Despite this, there are still many questions about how the insurance sector can offer risk management options in the face of increasing risk and uncertainty, especially in developing countries. However, it is clear that an integrated approach is needed to ensure that risk assessment is funded and risk prevention, mitigation and transfer solutions implemented to help those most vulnerable to climate change. [15] According to a recent study by Deloitte, the insurance industry is not prepared. [16]
Reinsurers that provide insurance for insurance companies are also likely to be affected by climate change. As natural disasters become more frequent and severe, reinsurers may have to pay more claims, resulting in higher premiums for insurers. These are similar sectors that operate using similar mechanisms such as underwriting, investment, claims, expense management and reinsurance that affect each other and the respective policyholders. Government regulation at all levels covers the right to start a business, types of risks, consumer protection and specific contracts, including reinsurance. Thus, although some differences exist due to the fact that direct insurers are more heavily regulated than reinsurers, it makes sense to have a unified regulatory system for both types of insurance within a jurisdiction. The main reason for this is that the reinsurance sector is considered a more specialized sector and does not involve direct interaction with consumers.[17]
The insurance industry can also play a role in mitigating the effects of climate change. It is one of the world's largest institutional investors and will influence investment decisions such as climate change, reduction of carbon emissions or investing in alternative energy sources. [18]
According to some economists, it is often more economical to prevent damage from natural disasters than to rely on insurance to cover losses after natural disasters occur. They say insurance may not be the optimal solution for all climate change-related situations, such as gradual changes like sea level rise, and typically only covers extreme events. [19]
There is no doubt that climate change poses significant challenges for society, and it is crucial to find ways to alleviate these challenges. While great emphasis is placed on laws and regulations to address climate change, insurance can also play a key role by providing clear financial incentives and certainty. Although private insurers are in a position to bear most of the risk, relying solely on them is not ideal. Because public projects and government intervention are often required to mitigate large-scale risks associated with climate change, it may be most effective for government to take a leading role in providing climate change insurance as a way to address these risks. [20]
Effective policy change requires a combination of both market incentives and government regulation. Well-designed insurance programs can encourage actions that reduce the likelihood of climate-related disasters and should not be viewed as a substitute for other prevention and adaptation methods.
