AM0021 — Baseline Methodology for decomposition of N2O from existing adipic acid production plants

About this methodology

Projects destroy nitrous oxide produced as a by-product of adipic acid manufacture. The method measures the greenhouse gas emissions prevented by that destruction.

How methodology v3 reads projects of this type

What CarbonMeld reads

  • shown

    Grid emission factor: the methodology sets rules for it in some cases. CarbonMeld reads it in the project's documents. CM-F-AM0021-GRID-EF

    Link
  • shown

    Leakage: the methodology sets rules for it in some cases (AM0021 v03 Leakage, p. 13). CarbonMeld reads it in the project's documents. CM-F-AM0021-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 (AM0021 v03 baseline Step 2, p. 5). Our current method does not assess it. CM-F-AM0021-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-AM0021-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.

History and transitions

All 5 versions

  • v03adopted 13 Feb 2009source

    Revision includes the procedure in Annex 1 to calculate the adipic acid production in cases it cannot be measured directly.

  • v02.2adopted 2 Aug 2008source

    Editorial revision to add footnote 3 to clarify that volume of gas and N2O concentration should be measured simultaneously and at same basis (wet or dry) and should be expressed at the normal conditions. The clarification made in the …

  • v02.1adopted 16 May 2008source

    “Tool to calculate baseline, project and/or leakage emissions from electricity consumption” replaces the withdrawn “Tool to calculate project emissions from electricity consumption”.

  • v02adopted 30 Nov 2007source

    Include the following Clear procedures for the identification of the baseline scenario; Clearer procedures for estimating the baseline N2O emission using equations; A requirement to measure the N2O emissions before the destruction unit to …

  • v01adopted 25 Feb 2005source

    Initial adoption.

Which registries list projects under AM0021?

In CarbonMeld's data, AM0021 projects are on one registry: CDM (4 projects, 4 registered).

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.

3 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.
