Concept Note

VM0039, v1.1 provides a framework for the quantification of GHG emission reductions associated with the production and installation of Foam Stabilized Base (FSB) and/or asphalt emulsions as replacements for Hot Mix Asphalt (HMA) in road construction projects in the United States. The proposed major revision to this methodology comprises the following:

  • Re-assess and update the baseline performance benchmark to meet VCS requirements and ensure alignment with industry trends and research.
  • Expand the geographical scope of the methodology to include Canada (North America) due to similarities in technologies and practices in road construction.
  • Re-assess and possibly revise the default factor on upstream displacement that was published in version 1.1 of the methodology.


The concept note was submitted by Global Emissionairy, LLC (external) and is currently at “Step 2: Methodology Concept Note Development” of the VCS Methodology Development and Review Process, v4.4 (PDF).
