AMS-III.B — Switching fossil fuels

About this methodology

Projects switch to lower-emission fossil fuels; the method measures emissions saved in providing the same energy service.

How methodology v3 reads projects of this type

What CarbonMeld reads

  • shown

    Grid emission factor: the methodology sets rules for it in some cases. CarbonMeld reads it in the project's documents. CM-F-AMS-III-B-GRID-EF

    Link

  • 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).

Figures set against the methodology's own values

  • Integrity comparison

    The small-scale limit is 60 kt CO2e per year (p. 5). CarbonMeld compares the project's annual estimate with it. CM-F-AMS-III-B-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

    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-B-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.

Which registries list projects under AMS-III.B?

In CarbonMeld's data, AMS-III.B projects are on 3 registries: CDM (92), Verra (5) and American 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.

RegistryProjectsRegisteredProjects list
CDM (UNFCCC)9224See the list
Verra (VCS)50See the list
American Carbon Registry (ACR)10See 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 (13 November 2026); projects in a later status, such as awaiting verification approval, late to verify or completed, are not in that column.

9 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.
