Sustainability

Low environmental-footprint proxy from clean air, climate resilience, car-light transportation, low smoke, disaster safety, and sea-level risk scores.

Scale0-100

Higher values rank better for this score.

How It's Calculated

The latest published score is normalized to a 0-100 scale. The method below explains what the score rewards, with technical source metadata available for audit.

Scoring Method

How the ranking is built

Sustainability is a low environmental-footprint proxy that rewards places with cleaner air, stronger climate resilience, car-light transportation options, lower smoke exposure, lower disaster risk, and lower sea-level-rise exposure.

  1. 1

    The score is a weighted average of already-published 0-100 component scores.

  2. 2

    Weights are 18% Clean Air, 18% Climate Resilience, 18% Car-Light Living, 12% Transit Access, 12% Low Car Dependence, 8% Low Wildfire Smoke Risk, 8% Natural Disaster Safety, and 6% Low Sea-Level Rise Risk.

  3. 3

    The scorer fails fast if component weights do not sum to exactly 1 within a tiny floating-point tolerance.

  4. 4

    If a component is unavailable, it is imputed as a neutral 50 rather than treated as positive evidence, and the scorer still requires at least 80% component-weight coverage.

Statistics Feeding This Score

  • Clean Air

    Published air-quality score from EPA AirData PM2.5, ozone, and AQI inputs.

    Source: Published score components
  • Climate Resilience

    Published future climate-risk composite from CMRA-derived heat, drought, wildfire, flood, sea-level, and hurricane signals.

    Source: Published score components
  • Car-Light Living

    Published transportation composite from walkability, transit, low car dependence, and bike/pedestrian commute behavior.

    Source: Published score components
  • Transit and low car dependence

    Published transit access and low car-dependence scores used as direct low-driving lifestyle proxies.

    Source: Published score components
  • Smoke and disaster risk

    Published low wildfire-smoke and natural-disaster safety components.

Known Limits

  • This is a low environmental-footprint proxy, not a full household carbon-accounting model.
  • It does not yet include clean-electricity mix, exact water stress, building energy use, recycling policy, local food systems, or address-level land-use data.
  • Transit and car-light scores are place-level proxies from commute behavior and mapped transit stops, not exact lifestyle emissions for a specific household.
  • Some users may prefer sustainability through rural self-sufficiency rather than urban car-light living; use this alongside the more survival-oriented Prepper / Resilience score when that distinction matters.
