This methodology provides procedures to estimate enteric methane (CH4) emission reductions generated from the inhibition of methanogenesis through the introduction of a feed additive into ruminants’ diet. The methodology considers emission reductions from enteric fermentation and is globally applicable for all livestock operations which manage ruminants’ diet.

The proposed revisions to the methodology will expand the applicability conditions to include any type of feed additive approved for animal use and with scientific evidence demonstrating its efficacy. The revisions also increase the stringency of the procedure by which project proponents establish the enteric methane emission reduction factor to better reflect latest best practices within the animal sciences field.

The revisions were prepared by an independent external expert and were posted for public consultation. The methodology was also circulated to the FAO feed additive working group and leading experts in enteric methane emissions. Verra’s in-house experts and a second, independent external expert will review the methodology to assess the revisions, determine whether the revised methodology is at least as rigorous as the previous version, and that the revised methodology complies with the VCS Methodology Requirements. Given the number of experts involved in drafting and reviewing the revisions (including world-leading experts on the subject) and the technical nature of the revisions, the assessment will not include review by a validation/verification body.
