AMS-III.AR — Substituting fossil fuel based lighting with LED/CFL lighting systems

About this methodology

Projects replace portable fuel-burning lamps with rechargeable electric lighting. The method measures emissions avoided by reducing the fuel used for lighting.

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.AR v09 equation, p. 11). CarbonMeld reads it in the project's documents. CM-F-AMS-III-AR-GRID-EF

  • shown

    Usage rate of the devices: the methodology sets rules for it (AMS-III.AR v09 paras 19–20, p. 8). CarbonMeld reads it in the project's documents. CM-F-AMS-III-AR-USAGE

    Link
  • reading

    Emission factor: CarbonMeld does not print a factor above 2.4 tCO2/MWh. This limit is the highest value of the methodology (p. 15). CM-F-AMS-III-AR-EF-BOUND

    upper bound: 2.4 tCO2/MWh · source: AMS-III.AR v09 (tmp/factsheet-20261003/methodology_texts/AMS-III.AR.txt), p. 15

  • 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

    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-AR-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.AR?

In CarbonMeld's data, AMS-III.AR projects are on 3 registries: CDM (23), Gold Standard (22) 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)2316See the list
Gold Standard (GS)2221See 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 (14 November 2026); projects in a later status, such as awaiting verification approval, late to verify or completed, are not in that column.

17 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.
