The proposed revision methodology expands on VM0041 to allow the use of a vaccine pathway. The vaccine pathway is intended to reduce methanogenesis by suppressing the growth and performance of microbes that produce methane in the rumen of ruminant animals.
Summary of Development
- In March 2026, the development of this revision was rejected per the VCS Methodology Development and Review Process (PDF). After careful review, Verra determined that the proposal’s climate impact was not as high as that of other ideas. Verra will therefore not proceed this approach to the full methodology development process at this time.
