    Climate Risks Assessment

    Three pillars of climate intelligence — each covering exposure analysis, financial impact, and actionable strategies.

    Quantifies an asset's exposure to acute and chronic physical climate hazards — from heatwaves and droughts to coastal flooding and tropical cyclones. Scores are normalized 0–10 across 9 hazards and 3 warming scenarios.

    Water Stress

    Water demand vs. supply imbalance under climate pressure.

    Heatwave

    Days per year exceeding historical temperature thresholds.

    Heat Stress

    Combined heat and humidity impact on human health and productivity.

    Cold Spell

    Extreme cold events disrupting operations and supply chains.

    Fire Weather

    Combined conditions driving wildfire risk using the FWI index.

    Heavy Precipitation

    Frequency of extreme rainfall events above the 99th percentile.

    Drought

    Hydrological drought intensity via the PDSI index.

    Tropical Cyclones

    Probability and intensity of cyclone events and storm surges.

    Floods

    Composite flood risk from river overflow, surface runoff and storm surge.
