Verra has released Verified Carbon Standard (VCS) Methodology VM0039 Foam Stabilized Base and Emulsion Asphalt Mixtures in Pavement Application, v1.1. This is a revision of VM0039 Methodology for Use of Foam Stabilized Base and Emulsion Asphalt Mixtures in Pavement Application, v1.0, and it constitutes a minor revision under the Methodology Development and Review Process, v4.4 (PDF). The new version includes a discount factor for upstream emission reductions that result from reduced energy consumption from the mining, processing, and transport of aggregates, as per the VCS Methodology Requirements, v4.4 (PDF).
VM0039 provides a framework for the quantification of greenhouse gas emission reductions associated with the production and installation of foam stabilized base and/or asphalt emulsions as substitutes for hot mix asphalt in road construction projects within the United States.
The revision to VM0039 reflects Verra’s commitment to enhancing the integrity and impact of the VCS Program, per the New Era for Verra initiative and in alignment with the August 2023 update to the VCS Program.
Additionally, Verra has received a proposal for a major revision to VM0039. The proposed changes would update the methodology’s performance benchmarks and expand its geographic scope.
Projects seeking to complete registration in the VCS Program under VM0039, v1.0 must request pipeline listing on the Verra Registry before June 15, 2024, and complete validation by December 15, 2024.
