🌍 '''Climate risk assessment''' is the systematic process by which [[Definition:Insurance carrier | insurers]], [[Definition:Reinsurance | reinsurers]], and related financial institutions evaluate how physical and transitional climate-related hazards affect their [[Definition:Underwriting | underwriting]] portfolios, investment holdings, and long-term business viability. Unlike traditional [[Definition:Catastrophe modeling | catastrophe modeling]], which focuses on the probability and severity of discrete natural perils, climate risk assessment grapples with the compounding, non-stationary nature of climate change — rising sea levels, shifting wildfire zones, intensifying tropical cyclones, and the economic disruptions accompanying the transition to a low-carbon economy. For the insurance industry, which prices risk over future time horizons, this assessment sits at the heart of both product sustainability and strategic planning.

🔬 Insurers approach climate risk assessment through multiple lenses. Physical risk analysis uses forward-looking climate scenarios — often aligned with frameworks from the Intergovernmental Panel on Climate Change (IPCC) or the Network for Greening the Financial System (NGFS) — to project how changing weather patterns will alter [[Definition:Loss frequency | loss frequency]] and [[Definition:Loss severity | severity]] across [[Definition:Property insurance | property]], [[Definition:Agricultural insurance | agriculture]], [[Definition:Marine insurance | marine]], and other exposed lines. Transition risk analysis examines how regulatory shifts, carbon pricing, technological disruption, and changing consumer behavior might impair the value of insured assets or the insurers' own investment portfolios — particularly holdings in fossil fuel industries. Leading [[Definition:Catastrophe modeling | catastrophe model]] vendors and specialist climate analytics firms now offer tools that integrate climate projections into [[Definition:Pricing model | pricing models]] and [[Definition:Portfolio management | portfolio accumulation]] analyses, though significant uncertainty remains around the pace and distribution of climate impacts.

📋 Regulatory and disclosure momentum has made climate risk assessment a governance-level priority rather than a purely technical exercise. The [[Definition:Task Force on Climate-related Financial Disclosures (TCFD) | TCFD]] framework — now embedded in mandatory disclosure rules in the UK, the EU (via the Corporate Sustainability Reporting Directive), Japan, Hong Kong, and Singapore — requires insurers to articulate how climate risks are identified, managed, and integrated into strategy. [[Definition:Solvency II | Solvency II]]'s Own Risk and Solvency Assessment (ORSA) increasingly expects climate scenario testing, and the [[Definition:National Association of Insurance Commissioners (NAIC) | NAIC]] in the United States has introduced climate risk disclosure surveys for larger insurers. Beyond compliance, robust climate risk assessment enables insurers to reprice or restructure coverage in high-exposure regions, develop new products such as [[Definition:Parametric insurance | parametric insurance]] for climate-vulnerable populations, and maintain the confidence of [[Definition:Rating agency | rating agencies]] and investors who increasingly view climate preparedness as a marker of institutional resilience.
