AM0028 — N2O destruction in the tail gas of Caprolactam production plants

About this methodology

Projects install units that destroy nitrous oxide in the tail gas of caprolactam production plants. The method measures the greenhouse gas releases avoided by this treatment.

How methodology v3 reads projects of this type

What CarbonMeld reads

  • shown

    Leakage: the methodology sets rules for it in some cases (AM0028 v06.0 Leakage paras 96–97, p. 31). CarbonMeld reads it in the project's documents. CM-F-AM0028-LEAKAGE

    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).

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

  • not assessed

    No legal requirement for the activity: the methodology sets rules for it (AM0028 v06.0 baseline, p. 30). Our current method does not assess it. CM-F-AM0028-REGULATORY-SURPLUS

    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-AM0028-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 AM0028?

In CarbonMeld's data, AM0028 projects are on 2 registries: CDM (18) 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)1813See the list
Verra (VCS)22See 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.

4 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.
