AMS-III.AF — Avoidance of methane emissions through excavating and composting of partially decayed municipal solid waste (MSW)
About this methodology
Projects aerate, excavate and sort waste in closed disposal sites, then compost its organic fraction. The method measures methane emissions avoided by this treatment.

How methodology v3 reads projects of this type
What CarbonMeld reads
A confirmed investment analysis A-INVEST
The documents show a project-level additionality test, the validation confirmed it, and it is an investment analysis (a numeric test of the project's finances with and without carbon revenue).
A methane activity the law requires A-LEGAL
The rule applies to projects that capture or avoid methane. These are landfill gas, manure, wastewater, composting and coal-mine methane. They also include orphan wells, oil and gas leaks, rice, enteric methane and household biogas. The documents state that the law requires the activity. Or the documents state that a law requires the capture of the gas. An activity that the law already requires is not additional. If the documents show that the baseline already deducts the amount that the law requires, CarbonMeld takes no point.
Figures set against the methodology's own values
- Integrity comparison
The small-scale limit is 60 kt CO2e per year (p. 2). CarbonMeld compares the project's annual estimate with it. CM-F-AMS-III-AF-SMALL-SCALE-LIMIT
small-scale limit: 60 kt CO2e per year
Set by the methodology or the programme, not assessed by our current method
- not assessed
Leakage: the methodology sets rules for it in some cases (AMS-III.AF v01 Leakage para 19, p. 6). Our current method does not assess it. CM-F-AMS-III-AF-LEAKAGE
- not assessed
Tracking of the end use: the methodology sets rules for it (AMS-III.AF v01 para 25 monitoring, p. 8). Our current method does not assess it. CM-F-AMS-III-AF-END-USE-TRACKING
- not assessed
Social safeguards and consent of communities (FPIC): any such rules come from the programme, not the methodology. Our current method does not assess it. CM-F-AMS-III-AF-SAFEGUARDS-FPIC
Not applicable to this type — never a gap in our current method
The criterion does not apply to this methodology. Our current method never counts it as a gap.

Which registries list projects under AMS-III.AF?
In CarbonMeld's data, AMS-III.AF projects are on 2 registries: International Carbon Registry (3) and Verra (1). Being listed on a registry is not the same as being registered: the «Registered» column counts the projects each registry shows as registered, and credits are issued only after each verification.
| Registry | Projects | Registered | Projects list |
|---|---|---|---|
| International Carbon Registry (ICR) | 3 | 2 | See the list |
| Verra (VCS) | 1 | 0 | See the list |
Counts of project records in CarbonMeld's data, with or without a CarbonMeld analysis. «Registered» counts the records whose current registry status is «registered», as last read (15 November 2026); projects in a later status, such as awaiting verification approval, late to verify or completed, are not in that column.
2 of these projects have no number: additionality, quantification or both have no public grade of their type of project that applies to them yet. Their pages show the analysis.
