Methodology for Quantifying GHG Emission Reductions from Plastic Waste Diversion into Concrete

The proposed methodology applies to project activities that reduce greenhouse gas (GHG) emissions by diverting low-value plastic waste from landfills and incineration, and embedding it permanently into concrete products as a partial aggregate replacement.

On March 16, 2026, the development of this revision was rejected per the VCS Methodology Development and Review Process (PDF) due to the following reasons:

• Available resources, including funding, Verra staff time, and external expertise, are limited.
• This proposal does not satisfy the criteria under Section 3.1.11 of the MDRP as fully as other ideas.
