Revision to VM0043: Methodology for CO2 Utilization in Concrete Production, v1.0

VM0043 v1.0 is applicable to project activities that use waste CO₂ as a feedstock in the production of concrete. GHG emissions are reduced by incorporating waste CO₂ in concrete and lowering the amount of cement required in the production of concrete.

The proposed revision expands the scope of VM0043 to include project activities that use CO₂ as a feedstock in the production of concrete (both ready-mix and pre-cast), concrete additives, recycled concrete aggregates, and reclaimed water at concrete plants. The proposed methodology is globally applicable.

The proposed methodology is being developed by CarbonCure Technologies Inc. (external) and CarbonBuilt (external). On December 19, 2024, the development of this methodology was put on hold. Verra will consider resuming the development once the following criteria are met:

• Resources are available to support the methodology development process
• The development process can be prioritized over other VCS methodology development work according to the VCS Methodology Development and Review Process.

Verra will reassess whether to resume the development of this methodology in Q2 2025.

Stakeholders interested in collaborating during methodology development or developing projects that this methodology might enable are encouraged to contact methodologies@verra.org. Please include the Methodology Development ID# CN0128 in the subject line.
