📋 Evidence Levels & Conservative Crediting (click to expand)

Level 1: Desk-based estimate — Use household/facility counts + IPCC defaults. F=1.0, U=1.0. Suitable for programme screening.
Level 2: Programme MRV — Add verification surveys, photos, GPS, functionality checks. Adjust F for flood risk (-0.3 flooded, -0.2 collapsed). Suitable for carbon finance with auditor sign-off.
Level 3: Locally calibrated — Measure flux / use locally measured emission factors. Refine MCF values for your context.

Conservative rules: Do NOT credit systems that are flooded, collapsed, overflowing, unused, or where sludge is dumped untreated. Do NOT assume all "improved" latrines reduce methane (dry systems yes; wet pits may increase CH₄). Apply F < 1.0 where functionality is uncertain. Keep estimate low, central, high range.
