AMS-III.R — Methane recovery from livestock and manure management at households and small farms

About this methodology

Projects recover and burn methane from manure or mixed agricultural wastes, including in household biogas digesters. The method measures reductions from preventing methane releases and eligible displaced energy supplies.

How methodology v3 reads projects of this type

What CarbonMeld reads

  • shown

    Grid emission factor: the methodology sets rules for it in some cases (AMS-III.R v05.0 project emissions para 16, p. 8). CarbonMeld reads it in the project's documents. CM-F-AMS-III-R-GRID-EF

  • shown

    Fraction of non-renewable biomass (fNRB): the methodology sets rules for it in some cases (AMS-III.R v05.0 applicability, p. 3). CarbonMeld reads it in the project's documents. The fNRB enters only through a combined AMS-I.E part. Where the documents apply AMS-I.E with this methodology, CarbonMeld's fNRB rules apply to that part. CM-F-AMS-III-R-FNRB

  • 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).

  • No usage monitoring (cookstoves, biogas, water treatment) Q-NO-USAGE-MONITORING

    Cookstoves, biogas and water treatment: the monitoring or verification reports that CarbonMeld read give no usage rate. For biogas and water treatment, the rule applies where the methodology asks for a usage survey or an operation survey. Where CarbonMeld read no monitoring or verification report, the rule does not apply. A usage check by the verifier counts as usage monitoring. Operation logs and the share of units still in operation count too. CarbonMeld applies this rule only where a check of the documents has confirmed its condition; without that check, the rule takes no points.

Deductions that can apply

  • 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.

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.R v05.0 section 5.4 Leakage, p. 8). Our current method does not assess it. CM-F-AMS-III-R-LEAKAGE

  • not assessed

    Tracking of the end use: the methodology sets rules for it (AMS-III.R v05.0 monitoring para 21, p. 9). Our current method does not assess it. CM-F-AMS-III-R-END-USE-TRACKING

    Link
  • 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-R-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.

The general rules apply as well. Read the general rules.

Top projects using AMS-III.R

This page ranks projects using AMS-III.R by their CarbonMeld document-based ratings. The rank compares project ratings; it is not a rating of the methodology itself.

8 rated projects of the 54 tracked in this methodology · average rating 4.4/10 · ranked by CarbonMeld's document-based rating: additionality, quantification, permanence (where carbon is stored) and claim safety.

Which registries list projects under AMS-III.R?

In CarbonMeld's data, AMS-III.R projects are on 2 registries: CDM (46) and Verra (8). 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.

RegistryProjectsRegisteredProjects list
CDM (UNFCCC)4640See the list
Verra (VCS)81See the list

Counts of project records in CarbonMeld's data, with or without a CarbonMeld analysis, so they can be larger than the ranking below. «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.
