Climate and Nature Financial Risk
The Global Risks Alliance (GRA)
As climate hazards grow, some property and activities may become uninsurable at affordable prices, and lenders may stop financing them. Adaptation, through flood defences, building standards, land-use change and nature-based solutions, can keep risks insurable. This page sets out how adaptation affects insurability and finance, how it is measured, and which public and private institutions decide.

Layers and dates
Climate adaptation and insurability is the question of whether property and activities stay insurable and financeable as hazards grow, and how adaptation keeps them so. Defences, standards and land-use change lower expected loss; public schemes shape incentives. Insurers, governments, local authorities and lenders hold the decisions.

Risk reduction and protection gaps. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Risk-based premiums show where hazard is rising. Very high premiums can push owners to drop cover, shifting losses to lenders and governments.
Defences, elevation, fire-resistant materials and wetlands reduce damage. If recognised in pricing, they can restore insurability.
Subsidised pools and backstops keep cover available but can encourage building in risky areas unless paired with risk reduction requirements.
Adaptation benefits are spread across owners, insurers and public budgets, so no single party funds it fully. Financing models try to capture the shared benefit.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Insurability | The conditions under which a risk can be covered at a price buyers can pay and insurers can sustain. |
| Impact underwriting | Insurance practice that rewards policyholders for adaptation measures that reduce expected loss. |
| Backstop | A public arrangement that absorbs losses beyond what private markets will carry. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Premiums as a share of household income in high-risk areas | percent | periodic | Regulator and survey data | ESTIMATED |
| Properties with adaptation measures recognised in pricing | count or share | periodic | Insurer and programme data | REPORTED |
| Public pool and backstop exposure | currency | annual | Pool records | OFFICIAL |
| Adaptation investment | currency per year | annual | Public budgets and tracking studies | REPORTED |
| Avoided losses from defences | currency per year | per study | Benefit studies | MODELLED |
| Insurance availability index | index | periodic | Regulator studies | ESTIMATED |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Climate and Nature Financial Risk prepares evidence. The decisions below are taken by the authorities named, under their own rules, and never by the platform.
| Who decides | The question | Evidence this page serves |
|---|---|---|
| Insurers | Whether and how to recognise adaptation measures in pricing | Loss reduction evidence and data |
| Governments | Whether to establish or reform public schemes and backstops | Scheme designs, costs and incentives |
| Local authorities | Which adaptation investments and land-use rules to adopt | Hazard and loss evidence |
| Lenders | Whether adaptation changes lending terms | Collateral risk and insurance evidence |
When expected losses rise, risk-based premiums rise. At some point cover becomes unaffordable for households and firms, or insurers limit capacity, leaving losses uninsured. Protection gaps are largest in lower-income countries, but they are also growing in high-risk areas of wealthier economies.
Adaptation reduces vulnerability and exposure, lowering expected losses and helping keep risks insurable. Insurance can encourage adaptation through pricing signals, but only if risk reduction is reflected in premiums. Public schemes, risk pools and other mechanisms can help where private markets withdraw, with trade-offs for public budgets and incentives.
Comparing economic and insured losses. Economic losses are uncertain in data-poor regions.
Estimating how risk reduction lowers expected losses, using climate and atmospheric science. Benefits depend on maintenance and future hazards.
Relating premiums to incomes, with spatial statistics and geostatistics. Household data are limited.
Comparing public, private and blended arrangements. Context limits transfer of lessons.
