Verra is pleased to announce that revisions to the Methodology for the Reduction of Enteric Methane Emissions from Ruminants Through the Use of 100% Natural Feed Supplement are open for a 30-day public consultation from 16 August through 14 September 2021.

This methodology addresses enteric methane (CH4) emission reductions achieved by introducing a 100% natural feed additive into ruminants’ diet. The methodology considers emission reductions from enteric fermentation and is globally applicable.

The proposed revisions to the methodology will expand the applicability conditions to:

  1. include any type of feed additive approved for animal use and with scientific evidence demonstrating its efficacy;
  2. update the evidence required to establish the enteric methane emission reduction factor; and
  3. account for potential project emissions from manure decomposition within the project boundary.

The methodology will also be updated to reflect new default factors derived from the 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.
