AMS-III.AU — Methane emission reduction by adjusted water management practice in rice cultivation

About this methodology

Projects change rice cultivation and water management, for example by allowing fields to dry between flooding periods. The method measures methane reductions from less anaerobic decomposition in the soil.

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.

Figures set against the methodology's own values

  • Integrity comparison

    The small-scale limit is 60 kt CO2e per year (p. 4). CarbonMeld compares the project's annual estimate with it. CM-F-AMS-III-AU-SMALL-SCALE-LIMIT

    small-scale limit: 60 kt CO2e per year

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

  • not assessed

    Usage rate of the devices: the methodology sets rules for it (AMS-III.AU v04.0 para 36, p. 17). Our current method does not assess it. CM-F-AMS-III-AU-USAGE

  • 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-AMS-III-AU-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 4 versions

  • v04.0adopted 28 Nov 2014source

    Takes into account the proposed standardized baseline PSB0019: “Standardized baseline for methane emissions from rice cultivation in the Republic of the Philippines”, and introduces a simplified option for emission reductions calculation …

  • v03.0adopted 20 Jul 2012source

    Includes a simplified approach to calculate emission reductions using default values derived from IPCC tier 1 approach, as an alternative to the reference field approach.

  • v02.0adopted 2 Mar 2012source

    Allows for an alternative procedure to ensure efficient fertilization.

  • v01.0adopted 15 Apr 2011source

    Initial adoption.

Which registries list projects under AMS-III.AU?

In CarbonMeld's data, AMS-III.AU projects are on 2 registries: Verra (285) and CDM (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.

RegistryProjectsRegisteredProjects list
Verra (VCS)2851See the list
CDM (UNFCCC)41See 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.

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.
