AM0027 — Substitution of CO2 from fossil or mineral origin by CO2 from biogenic residual sources in the production of inorganic compounds
About this methodology
Projects use residual CO2 from biological processes instead of fossil or mineral CO2 to manufacture inorganic compounds. The method measures emission reductions from changing the feedstock.

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).
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-AM0027-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.

History and transitions
-
v03.0adopted 9 Sept 2021source
Clarify the source of baseline CO2; expand the eligibility of sources CO2 in the baseline; and address provisions that could potentially lead to claiming emission reductions from CO2 sequestration.
-
v02.0adopted 29 Sept 2006source
Clarify that the approved methodology is applicable to project activities where the generation of CO2 from fossil or mineral sources in the baseline is only for the purpose of producing CO2 used for the production of inorganic compounds …

v01.0adopted 25 Nov 2005source

Projects using AM0027
Browse 1 published project using AM0027, listed alphabetically. There is no ranking for this methodology yet: it appears here automatically once 5 of its projects not in the pipeline or under validation are rated.

Which registries list projects under AM0027?
In CarbonMeld's data, AM0027 projects are on one registry: CDM (1 project, 1 registered).
| Registry | Projects | Registered | Projects list |
|---|---|---|---|
| CDM (UNFCCC) | 1 | 1 | See 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.
