Impact & Verification
Not all cleanup records are equal. letscleanup.org distinguishes between verified and reported impact — and explains exactly how each metric is calculated, so the civic record is honest, not inflated.
Why Measurement Matters
Most cleanup efforts go unrecorded. A group of 30 people cleans a lake for 3 hours, collects 200 kg of waste — and the only evidence is a few WhatsApp photos that disappear from memory within weeks. This makes it impossible to understand cumulative impact, identify which areas need recurring attention, or demonstrate to institutions that community-led civic action produces measurable results.
letscleanup.org was built to fix this. Every cleanup event on the platform generates a permanent record — not just of intent, but of verified, structured proof.
Verified vs Reported
✔ Verified (QR)
Verified metrics come from events that use letscleanup.org's QR attendance system. Each participant scans a QR code at the event — this records their check-in time, creating a tamper-evident attendance log.
RSVP / Reported
Reported metrics come from events that use RSVP-only attendance — no QR verification. The organiser submits their best estimate of actual participants and duration after the event.
Both types of events are accepted and recorded. The distinction is clearly visible on every event page, organiser profile, and the platform'simpact dashboard— so the record is honest and comparable.
The Three Core Metrics
Participants
Count of individuals who scanned the event QR code during the cleanup window.
Count declared by the organiser in their post-event impact submission.
Why it matters: Participant count is the most visible signal of community engagement. It tells you how many people cared enough to show up.
Participant-Hours
Verified participants × actual event duration in hours, calculated from QR timestamps.
Reported participants × organiser-declared duration.
Why it matters: Participant-hours normalise impact across events of different scales. A 5-person 4-hour cleanup and a 20-person 1-hour cleanup both produce 20 participant-hours.
Area Cleaned
Calculated from the cleanup polygon drawn by the organiser at the time of proposal submission. The polygon area in square metres is locked at approval and cannot be modified.
Same polygon-based calculation — the area metric is consistent across verified and unverified events since it derives from the submitted geography, not attendance.
Why it matters: Area cleaned provides a geographic scale to the impact. It anchors the effort to a real, locatable place.
The Civic Archive
Every completed and verified event on letscleanup.org is permanently added to theCivic Archive— a public record of all community cleanup activity on the platform. Metrics are locked at completion and cannot be modified retroactively.
The archive is also aggregated into theImpact Dashboard, which shows cumulative totals across all events — broken down by state and terrain type. This creates a living picture of where civic environmental action is happening in India.
