13. Waste handling and disposal
AMS-III.Y. applies to project activities that avoid or reduce methane emissions from anaerobic wastewater treatments and/or anaerobic manure management systems through the removal of volatile solids. The separated solids must be further treated, used, or disposed of in a manner that reduces methane emissions.
Please note:
- CDM methodology AMS-III.Y. will be inactivated as a standalone methodology in the VCS Program on July 1, 2027. Projects that request registration on the Verra registry on or after July 1, 2027 must apply VMR0018, v1.0. See “Implications for VCS Projects” below for more details.
- On July 5, 2024, Verra released Clarifications to AMS-III.Y. Methane Avoidance through Separation of Solids from Wastewater or Manure Management Systems (PDF). All projects using AMS-III.Y. must apply these corrections and clarifications.
- AMS-III.Y. will be inactivated as a standalone methodology in the VCS Program on July 1, 2027.
- Projects that request registration on or after July 1, 2027 must apply VMR0018, v1.0.
- Registered projects and project activity instances registered under AMS-III.Y. must update to an active version of VMR0018 at their next crediting period renewal submitted on or after July 1, 2027.
- For grouped projects registered using AMS-III.Y., new project activity instances added to the project on or after July 1, 2027 as part of a verification approval request must meet all applicability conditions in VMR0018. Such grouped projects must fully adopt VMR0018 to include new instances.
- Further requirements for projects that transition from AMS-III.Y. to VMR0018 are provided in VMR0018.
- Registered projects using AMS-III.Y. may update to VMR0018 during their crediting period using one of the following:
- Procedure to Change Project Methodology through a Project Description Deviation to align with VMR0018 for future monitoring periods, or
- Methodology Change and Requantification Procedure to align with VMR0018 for past and future monitoring periods and requantify the reductions from past verifications
