AMS-III.AQ — Introduction of Bio-CNG in transportation applications
About this methodology
Projects produce and upgrade biogas into compressed fuel for vehicles. The method measures emission reductions from replacing fossil transport fuels with this biomass-derived gas.

How methodology v3 reads projects of this type
What CarbonMeld reads
- shown
- shown
Leakage: the methodology sets rules for it (AMS-III.AQ v02.0 Leakage paras 35–38, p. 10). CarbonMeld reads it in the project's documents. CM-F-AMS-III-AQ-LEAKAGE
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).
Set by the methodology or the programme, not assessed by our current method
- not assessed
Sustainability of the feedstock: the methodology sets rules for it in some cases (AMS-III.AQ scope, p. 3). Our current method does not assess it. CM-F-AMS-III-AQ-FEEDSTOCK-SUSTAINABILITY
- not assessed
Tracking of the end use: the methodology sets rules for it (AMS-III.AQ v02.0 para 24, p. 7). Our current method does not assess it. CM-F-AMS-III-AQ-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-AQ-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.AQ?
In CarbonMeld's data, AMS-III.AQ projects are on 4 registries: Verra (18), Universal Carbon Registry (3) and CDM (1), and 1 more. 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 |
|---|---|---|---|
| Verra (VCS) | 18 | 3 | See the list |
| Universal Carbon Registry (UCR) | 3 | 0 | See the list |
| CDM (UNFCCC) | 1 | 1 | See the list |
| Global Carbon Council (GCC) | 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.
