AMS-II.J — Demand-side activities for efficient lighting technologies
About this methodology
Projects replace household light bulbs with more efficient lamps. The method measures emissions avoided through reduced electricity use for lighting.

How methodology v3 reads projects of this type
What CarbonMeld reads
- shown
Leakage: the methodology sets rules for it (AMS-II.J v08, p. 4). CarbonMeld reads it in the project's documents. CM-F-AMS-II-J-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
Usage rate of the devices: the methodology sets rules for it (AMS-II.J v08, p. 7). Our current method does not assess it. CM-F-AMS-II-J-USAGE
- not assessed
Tracking of the end use: the methodology sets rules for it. Our current method does not assess it. CM-F-AMS-II-J-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-II-J-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-II.J
This page ranks projects using AMS-II.J by their CarbonMeld document-based ratings. The rank compares project ratings; it is not a rating of the methodology itself.
19 rated projects of the 108 tracked in this methodology · average rating 5.1/10 · ranked by CarbonMeld's document-based rating: additionality, quantification, permanence (where carbon is stored) and claim safety.

Which registries list projects under AMS-II.J?
In CarbonMeld's data, AMS-II.J projects are on 3 registries: CDM (76), Verra (27) and Gold Standard (5). 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 |
|---|---|---|---|
| CDM (UNFCCC) | 76 | 55 | See the list |
| Verra (VCS) | 27 | 1 | See the list |
| Gold Standard (GS) | 5 | 5 | 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 (12 November 2026); projects in a later status, such as awaiting verification approval, late to verify or completed, are not in that column.
