EPA WARM model
When we estimate pounds diverted from the landfill or CO₂ emissions avoided, we use EPA's Waste Reduction Model — the same model federal grant reviewers use. The math is shown alongside every estimated number.
Verified, Estimated, Directional, or Needs more data
Every number in every grant report carries one of four labels: Verified (a resident reported back that they actually did what we recommended), Estimated (we did the math from observed activity using a published model), Directional (useful for trend, not a precise number), or Needs more data (we don't have enough yet to publish responsibly). Nothing ships without a label.
We never double-count
If a single resident search led to multiple outcomes (a verdict, a feedback message, a confirmed action), only the strongest outcome is counted. No number is inflated by counting the same resident in multiple categories.
Your data stays your data
Your county's impact numbers belong to your county. We never publish anything that could identify an individual resident, facility, or county without permission.
Environmental-justice overlay when you need it
When your grant program requires an environmental-justice analysis, we can pair your participation map with EPA's public EJSCREEN demographic data. The overlay uses publicly-available demographic boundaries — no individual resident data leaves your county.
