Key Takeaways
- • Buildings account for 37% of global energy-related emissions, with property assets across 34 OECD countries valued at approximately US$111 trillion as of 2022, according to a new OECD report released January 14, 2026.
- • Climate-related risks affecting real estate are not systematically embedded in land-use planning, zoning, or investment frameworks, despite continued urban expansion into hazard-prone areas; European and Central Asian urban development between 1985 and 2020 increasingly occurred in flood zones due to land scarcity and weak zoning enforcement.
- • Real estate faces dual climate exposure: physical risks (floods, wildfires, heatwaves) and transition risks from regulatory, technological, and market changes tied to decarbonization, with severe shocks generating financial impacts through property value changes, lending constraints, and insurance cost volatility.
- • Global climate-related economic losses range between US$50 billion and US$430 billion annually, with climate hazards already affecting the usability, valuation, and affordability of real estate assets in highly exposed locations.
- • Climate-related risks remain primarily location-specific, yet systematic risk assessment and integration into institutional investment frameworks remains underdeveloped across OECD jurisdictions.
Summary
Climate-related risks are fundamentally reshaping real estate investment dynamics, according to a new report from the Organisation for Economic Co-operation and Development released on January 14, 2026. The OECD's analysis reveals that buildings represent a critical vulnerability point in global emissions architecture, accounting for 37% of energy-related emissions globally. Property assets across 34 OECD countries alone represent approximately US$111 trillion in value as of 2022, making real estate a substantial component of household and institutional wealth—yet this asset class faces mounting exposure to both physical and transition climate risks.
The report identifies a critical gap in risk management infrastructure: climate-related hazards are location-specific but remain inadequately embedded in land-use planning, zoning regulations, and investment frameworks. This structural deficiency has manifested in tangible patterns of urban development expansion into hazard-prone areas. In Europe and Central Asia specifically, urban development between 1985 and 2020 increasingly concentrated in flood zones, driven by land scarcity pressures and weak zoning enforcement mechanisms. This geographic concentration of investment in high-risk areas exposes institutional portfolios to correlated climate shocks.
The OECD distinguishes between two complementary risk vectors affecting real estate valuations. Physical risks—including floods, wildfires, and heatwaves—pose direct threats to asset usability and structural integrity. Transition risks stemming from regulatory tightening, technological disruption, and market repricing of carbon-intensive assets create indirect but consequential valuation pressures. These hazards are already measurably affecting real estate asset usability, market valuations, and affordability in highly exposed regions, with cascading effects through property lending conditions, investment capital flows, and insurance market dynamics.
Financial losses attributable to climate-related hazards are substantial and volatile. The OECD estimates global annual economic losses in the range of US$50 billion to US$430 billion, reflecting the wide variance in climate event frequency and severity across geographies and time horizons. These losses translate directly into investment performance impacts through property value depreciation, reduced lending availability as financial institutions reassess collateral quality, and rising insurance costs that compress net returns on real estate holdings.
The report's findings carry significant implications for institutional investors and asset owners managing real estate allocations: current investment frameworks systematically undervalue climate risk exposure, particularly in concentrated geographic portfolios. Institutional investors face pressure to embed systematic climate risk assessment into underwriting, valuation, and portfolio construction processes, even as regulatory and planning frameworks remain fragmented across OECD jurisdictions.
