7、e a growing protection gap without significantly increasing the cost of insurance,carriers need to focus on the causes of losses,enabling prevention and greater resilience.To be clear,many resilient solutions to combat these challenges exist today(sea walls and concrete home construction,for example

8、),but customer adoption has been slow due to compounding factors of affordability,awareness and availability.To drive adoption,investment by carriers and other impacted constituents(builders,financers,government)would provide long-term benefit but little has been done to date.2Climate risk and insur

9、ance:the case for resilience PwC|Climate risk and insuranceAddressing climate risk is a huge challenge,but we believe the industry can adapt to meet it.The associated costs are clear with the homeowners insurance market alone exceeding$100 billion in written premium,a change in loss ratio of just 10

10、0 basis points equates to over$1 billion in claims avoided.With centuries of experience managing climate and longevity risks and trillions of dollars in assets,the industry has the wherewithal to play a critical role by directing capital to where it can help mitigate risk.But to do so effectively,in

14、 insurance markets low resilience is abundant.Over the last five years,premiums in states with significant climate exposure notably Florida and California have generally increased more rapidly than the national average.At the same time,severe weather events have affected all parts of the country in

15、recent years,which is contributing to widespread premium increases.These higher premiums are forcing some consumers to forego homeowners insurance,which can lead to catastrophic results.For instance,consider the Texas wildfires of early 2024,where many damaged or destroyed homes were uninsured.Many

16、of the challenges of risk transfer in property insurance markets can be attributed to the fact that our physical infrastructure is not resilient.Most US property,infrastructure design and construction assume a less volatile climate.As a result,physical assets are highly vulnerable to increasingly fr

17、equent and severe weather events.Exacerbating this problem is rapid development in lower cost,high hazard geographies such as the San Bernardino/Inland Empire area of California.This has resulted in higher risks to not only property but also human mortality and morbidity.Despite higher risk profiles

18、,the models insurers use to price premiums dont fully account for rapidly changing climate risks and the tipping points that can lead to market exits.And regulators face a dilemma in that approving models and methodologies allowing insurers to charge premiums reflecting inherent risks could lead to

19、steep premium increases,fueling the emergence of insurance deserts as insurance becomes unavailable or unaffordable for consumers.4Unsustainable risks,declining resiliencePwC|Climate risk and insuranceUsing PwCs geospatial climate intelligence model.We predict a continued increase in severity of fre

21、and severity of hurricanes making landfall compared to historical levels.This underscores that insurers cannot plan for reduced burdens from catastrophe losses without taking significant measures to promote resiliency.Investment riskIncreasingly acute and severe weather events also contribute to ass

22、et devaluation.Municipal and corporate bonds make up a significant portion of insurer investment portfolios the NAIC estimated that the US insurance industry held approximately$500 billion in municipal bonds and$2.8 trillion in corporate bonds as of December 31,2022,totaling 39%of its total assets.T

23、hese instruments have long been central to duration matching strategies,but these assets increasing risk profiles will challenge carriers ability to meet capital requirements.In the case of municipal bonds,more intense storms,wildfires,droughts,heatwaves and floods impose higher costs on state and l

24、ocal governments,raising spending.In addition,storm damage and resulting declines in property value(coupled with climate-induced migration)can undermine the municipal tax base on the revenue side.In fact,climate change is already making it more difficult for some municipalities to service their bond

25、 payments and raise new capital for needed climate investments.And bond markets are watching.Fifteen-and 30-year municipal bonds have declined in appeal and ratings agencies have already noted weather-related challenges for coastal communities.For carriers,this could have knock-on effects related to

29、while exiting markets suffering the most from the effects of climate change sends stakeholders and the wider public conflicting messages and increases reputational risk for the industry.Regulatory riskAs regulators increase their focus on climate transition and climate risk,carriers may be subject t

30、o a myriad of climate-related regulations on public disclosure,including requirements from the SEC,the state of California,the EU Corporate Sustainability Reporting Directive(CSRD)and the International Sustainability Standards Board(IISB).Of specific relevance to insurers is how to measure Scope 3 G

31、HG emissions,including financed and insured emissions.Further challenges include differing approaches to measuring financed emissions,the nascent nature of insured emissions standards and the fact that emissions data for all asset classes isnt available yet.6Unsustainable risks,declining resilienceP

32、wC|Climate risk and insuranceTransition riskThe world isnt standing still in the face of climate risks.However,efforts to address them are introducing new ones for insurers.As initiatives to transition to lower greenhouse gas(GHG)emissions have become more far-reaching,such as the Inflation Reductio

33、n Acts earmarking of approximately$370 billion in tax credits,incentives and other financing to halve GHG emissions by 2030(compared to 2005 levels),carriers face increasing pressure from regulators and new underwriting requirements for more energy efficient technologies.In response to climate risk,

34、insureds are developing and adopting more climate-friendly technologies.But for insurers this creates both pricing disincentives and reserving uncertainty.Solar panels,for example,increase the overall insured value of a home,therefore increasing premiums compared to the same home without solar panel

35、s.Additionally,electric vehicles have different claims development and costs than their internal combustion counterparts.Without new underwriting and reserving approaches,insureds may be disincentivized to invest in more energy efficient solutions as the cost of insurance may be higher for such prod

39、earables in life and health).Considering increasingly severe weather trends,carriers may need to rethink traditional admitted insurance products to contemplate multi-year policies and other types of products such as parametric insurance.Parametric insuranceInsurers are starting to redefine the natur

40、e of coverage via the burgeoning parametric market.Parametric policies which determine whether a claims payment is warranted based on a pre-defined“trigger”such as amount of rainfall in a given time offer insureds a way to accept more risk for specific perils.This means that coverage is available,ge

41、nerally at lower cost than traditional products,and that the claims process is faster and more efficient for everyone.Moreover,parametric insurance can be more than just restitutive and promote sustainability.A prominent example is the Nature Conservancys use of parametric insurance to protect Hawai

42、is coral reefs.If hurricanes or tropical storms damage the reefs,then a parametric payout goes directly to restoring them.This also has a long-term benefit for insurers because a healthy ecosystem can significantly mitigate storm damage over the longer term.Carriers and their stakeholders are increa

45、isk transfer,these securities are typically purchased by institutional investors in other financial sectors.Making use of such products enables the industry to reduce the financial burden from catastrophes and frees up capital that can be invested in technologies or products that increase resilience

46、.For example,a large global insurer recently issued an ILS that also embedded innovative green features,including investment of the collateral into reconstruction and development projects.Another new product is sustainability-linked insurance,which is similar to sustainability-linked loans and green

47、 bonds.Sustainability-linked coverage offers premium incentives and rebates if policyholders meet stated environmental goals.This type of coverage is especially relevant for climate-resilient and clean energy transition projects as well as companies,communities and even individuals who are looking t

60、 resilience on its own.Accordingly,collaboration among many different stakeholders must occur to encourage wider effort and adoption.This includes active,ongoing carrier interaction with policymakers,regulators,other industries,customers and others.Regulators:First and foremost,insurers and regulato

61、rs need to work together on the serious risks climate change poses to the insurance industry and policyholders.Greater transparency in this regard can build acceptance of regulatory action,as well as encourage wider efforts to address climate-related challenges.As part of this effort,carriers should

62、 encourage regulators to account for the financial and economic costs of regulation and disclosures.To promote a robust insurance market and prevent taxpayers from becoming claims backstops,insurers and regulators need to arrive at solutions that enable the insurance industry to offer coverage to al

63、l potential customers and reduce the burden on“carriers of last resort,”which are increasingly becoming the only choice in many markets.A promising recent development in this area is the NAICs March 2024 issuance of its National Climate Resilience Strategy for Insurance plan,which sets clear goals a

64、nd direction for solvency.Policymakers:Mitigating climate risk will be expensive for everyone.Governments can incentivize resilience by offering meaningful funding for and tax concessions on a wide variety of resilience interventions and emissions lowering initiatives.While there has been some progr

65、ess in this area,insurers can do more to influence policy that helps mitigate climate risk and supports resilient communities.Lenders and banks:Insurers should collaborate with lenders and banks to incorporate resilient property incentives.Potential rate modifications or discounts for resilient home

66、 builds or retrofitting could incentivize adoption by both consumers and builders.Frequent monitoring and reappraisal that offers customers incentives could increase property longevity.Additionally,green bonds and other investments in the larger community could increase resiliency program reach and

67、adoption.Builders:Carriers should work with the construction industry to actively monitor and assess leading edge codes and standards,materials and construction/refurbishment techniques.This will help builders and property owners make more climate resilient choices and comply with local regulations

68、while enabling insurers to more accurately price loss patterns and potential costs.12PwC|Climate risk and insurance Climate and clean energy technology providers:Some carriers already collaborate with a variety of stakeholders to develop new products and services that facilitate the clean energy tra

73、Insurers and all stakeholders should do more to educate customers on the property and health risks of climate change and the underlying reasons for premium increases.They also should provide customers greater encouragement to take mitigation steps that can reduce coverage costs and availability.As o

74、ne example,a large insurer is informing its retail customers about sustainable mobility and electric vehicle transition.Another example is the California Department of Insurance,which recently released standards on wildfire safety and how individual properties stack up.Because California law makes p
