AM0031 — Bus rapid transit projects

About this methodology

Projects build or expand bus rapid transit systems for urban passengers. The method measures emission reductions against the transport modes passengers would otherwise use.

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-AM0031-GRID-EF

    Link
  • shown

    Leakage: the methodology sets rules for it (AM0031 v08.0 Leakage para 52, p. 20). CarbonMeld reads it in the project's documents. CM-F-AM0031-LEAKAGE

    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).

Set by the methodology or the programme, not assessed by our current method

  • not assessed

    Usage rate of the devices: the methodology sets rules for it (AM0031 v08.0 baseline emissions, p. 14). Our current method does not assess it. CM-F-AM0031-USAGE

    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-AM0031-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 AM0031?

In CarbonMeld's data, AM0031 projects are on 2 registries: CDM (15) and Verra (2). 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)1510See the list
Verra (VCS)20See 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.

One of these projects has no number: additionality, quantification or both have no public grade of its type of project that applies to it yet. Its page shows the analysis.
