Grid emission factor: the methodology sets rules for it in some cases (AM0022 v04 project boundary, p. 2). CarbonMeld reads it in the project's documents. CM-F-AM0022-GRID-EF
AM0022 — Avoided Wastewater and On-site Energy Use Emissions in the Industrial Sector
About this methodology
Projects introduce improved anaerobic treatment at existing industrial wastewater lagoons. The method measures methane emission reductions from changing the treatment system.

How methodology v3 reads projects of this type
What CarbonMeld reads
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).
A methane activity the law requires A-LEGAL
The rule applies to projects that capture or avoid methane. These are landfill gas, manure, wastewater, composting and coal-mine methane. They also include orphan wells, oil and gas leaks, rice, enteric methane and household biogas. The documents state that the law requires the activity. Or the documents state that a law requires the capture of the gas. An activity that the law already requires is not additional. If the documents show that the baseline already deducts the amount that the law requires, CarbonMeld takes no point.
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-AM0022-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 AM0022
This page ranks projects using AM0022 by their CarbonMeld document-based ratings. The rank compares project ratings; it is not a rating of the methodology itself.
6 rated projects of the 30 tracked in this methodology · average rating 4.5/10 · ranked by CarbonMeld's document-based rating: additionality, quantification, permanence (where carbon is stored) and claim safety.

Which registries list projects under AM0022?
In CarbonMeld's data, AM0022 projects are on 2 registries: CDM (26) and Gold Standard (4). 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) | 26 | 12 | See the list |
| Gold Standard (GS) | 4 | 4 | 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.
