Draft Methodology

CDM methodology AM0073 (external) is applicable to project activities where manure is collected from multiple livestock farms and subsequently treated in a single central treatment plant. Existing anaerobic manure treatment systems in multiple livestock farms are replaced with a central treatment plant with one or a combination of animal waste management systems (AWMS) that results in less GHG emissions.

The scope of the proposed minor revision includes:

  • incorporation of existing AM0073 Corrections and Clarifications:  E&C AM0073 (11Apr23) (PDF) and C&C AM0073 (15Jan24) (PDF).
  • incorporation of minor updates from M0284 and M0290 that aim to make the methodology more applicable and easier to implement for projects involving small farms by addressing monitoring and logistical challenges.
  • other minor improvement to language and readability.

Summary of Development

The proposed revision follows an alternative process, per Section 2.1.2 of the VCS Methodology Development and Review Process, v4.4 (PDF). Verra is leading and authoring the revisions, with input from technical experts. The draft revision is currently at “Step 3: Draft Methodology Development” of the VCS Methodology Development and Review Process (PDF).
