AMS-I.J — Solar water heating systems (SWH)

About this methodology

Projects install solar water heaters in homes or commercial buildings. The method measures emissions avoided by reducing electricity or fossil fuels used to heat water.

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-I.J v02 para 21, p. 6). CarbonMeld reads it in the project's documents. CM-F-AMS-I-J-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).

Deductions that can apply

  • No additionality test in the documents (renewable energy) A-TEST-NOT-STATED

    Renewable energy, power generation and supply: the documents read state no additionality test. A test that the documents do not name is a different case. It takes no points. CarbonMeld applies this rule only where a check of the documents has confirmed its condition; without that check, the rule takes no points.

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

  • not assessed

    Leakage: the methodology sets rules for it in some cases (AMS-I.J v02 §5.5, p. 9). Our current method does not assess it. CM-F-AMS-I-J-LEAKAGE

  • not assessed

    Usage rate of the devices: the methodology sets rules for it (AMS-I.J v02 para 5, p. 3). Our current method does not assess it. CM-F-AMS-I-J-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-AMS-I-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.

The general rules apply as well. Read the general rules.

Which registries list projects under AMS-I.J?

In CarbonMeld's data, AMS-I.J projects are on 4 registries: CDM (6), BioCarbon Registry (1) and Gold Standard (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.

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.

5 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.
