Verra has published a Request for Proposals (RFP) (PDF) for an independent expert review of a major revision to the Verified Carbon Standard (VCS) methodology VM0042 Improved Agricultural Land Management, v2.1, as well as to the VCS module VMD0053 Model Calibration, Validation, and Uncertainty Guidance for Biogeochemical Modeling for Agricultural Land Management Projects, v2.1.
The ongoing major revisions to VM0042 and VMD0053 will result in versions 3.0 of the methodology and module.
Under the scope of the major revision to VM0042, Verra has worked with diverse technical contributors to prepare the following draft revision documents:
- A red-lined version of the draft VM0042, v3.0
- A draft of the new Soil Sampling and Analysis Handbook
- A red-lined version of the draft VMD0053, v3.0, including an accompanying new Model Calibration and Validation Report Template
Verra expects that the independent expert review will start during the public consultation on the revisions to VM0042 and VMD0053.
Independent expert reviewers may submit a proposal to review all three draft revision documents or conduct a partial review with a focus on soil sampling and analysis, biogeochemical modeling, or woody biomass quantification. Verra welcomes proposals from academics, researchers, practitioners, consultants, validation/verification bodies (VVBs), and other experts with demonstrated experience in agronomy and using VM0042 and VMD0053.
Proposals must be submitted by email with the methodology development ID# M0264 in the subject line by August 15, 2025, to methodologies@verra.org. Verra plans to finalize the selection of the consultant(s) by August 31, 2025, with the work to begin as soon as possible after then.
