How each number is derived

The same meal is never counted in more than one category

  • Prevented
    Difference between the baseline 730-meal plan and the proposed AI recommendation (562 meals). Counted only when a human approves a reduced plan before service.
  • Recovered
    Observed meals confirmed safe after service and successfully distributed by a verified partner.
  • Nonrecoverable
    Observed surplus that fails the human-completed eligibility checklist or expires before pickup.
  • Forecast accuracy
    Rolling 30-day mean absolute percentage error of attendance prediction. Updated nightly.
  • Carbon estimate
    Estimated kg CO2e avoided from prevented plus recovered meals. Not audited carbon accounting.
All numbers above are prototype demonstration data, tracked locally for this session. The carbon figure is an estimate, not audited carbon accounting, based on 232 prevented or recovered meals and public ReFED methodology.
