No legal requirement for the activity: the methodology sets rules for it (AM0034 v05.1.1 applicability, p. 3). Our current method does not assess it. CM-F-AM0034-REGULATORY-SURPLUS
AM0034 — Catalytic reduction of N2O inside the ammonia burner of nitric acid plants
About this methodology
Projects use a catalyst inside nitric acid production equipment to destroy nitrous oxide. The method measures the resulting reduction in releases of this greenhouse gas.

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-AM0034-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.

v05.1.1adopted 29 Sept 2011source
Editorial amendment to provide more clarity on how statistical procedures are to be applied to the baseline and project data.
-
v05.1.0adopted 26 Nov 2010source
Includes a definition for abnormal campaign.
-
v05adopted 30 Jul 2010source
Measurement interval for the purpose of equations 3 and 6 changed to one hour (or less), instead of 2 seconds, to account for the output of AMS based on 2 second measurements and output of statistical procedure. Several editorial changes.
-
v04adopted 12 Feb 2010source

v03.2adopted 24 Nov 2008source
Editorial revision to correct a typo in the paragraph of “Project Campaign Length”.
-
v03.1adopted 2 Aug 2008source
Editorial revision to add footnote-3 and footnote-4 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 …

Top projects using AM0034
This page ranks projects using AM0034 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 57 tracked in this methodology · average rating 4.7/10 · ranked by CarbonMeld's document-based rating: additionality, quantification, permanence (where carbon is stored) and claim safety.

Which registries list projects under AM0034?
In CarbonMeld's data, AM0034 projects are on 2 registries: CDM (53) and Verra (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) | 53 | 49 | See the list |
| Verra (VCS) | 4 | 2 | 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.
