AMS-I.I — Biogas/biomass thermal applications for households/small users
About this methodology
Projects supply households and small users with heat from renewable biomass or biogas. The method measures emissions avoided by replacing fossil fuels for cooking, drying, water heating or space heating.

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).
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
No additionality test in the documents (renewable energy) A-TEST-NOT-STATED
Renewable energy, power generation and supply: the documents read state no additionality test. A test that the documents do not name is a different case. It takes no points. CarbonMeld applies this rule only where a check of the documents has confirmed its condition; without that check, the rule takes no points.
Set by the methodology or the programme, not assessed by our current method

Sustainability of the feedstock: the methodology sets rules for it (AMS-I.I v07 para 4, p. 4). Our current method does not assess it. CM-F-AMS-I-I-FEEDSTOCK-SUSTAINABILITY
- 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-I-I-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.

Top projects using AMS-I.I
This page ranks projects using AMS-I.I by their CarbonMeld document-based ratings. The rank compares project ratings; it is not a rating of the methodology itself.
10 rated projects of the 59 tracked in this methodology · average rating 4.9/10 · ranked by CarbonMeld's document-based rating: additionality, quantification, permanence (where carbon is stored) and claim safety.

Which registries list projects under AMS-I.I?
In CarbonMeld's data, AMS-I.I projects are on 3 registries: Gold Standard (56), CDM (2) and Universal Carbon Registry (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 |
|---|---|---|---|
| Gold Standard (GS) | 56 | 55 | See the list |
| CDM (UNFCCC) | 2 | 2 | See the list |
| Universal Carbon Registry (UCR) | 1 | 0 | See 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 (14 November 2026); projects in a later status, such as awaiting verification approval, late to verify or completed, are not in that column.
