Verra consults on VM0043 methodology revision for concrete CO2 utilisation

Verra has launched a public consultation on a significant revision to its VM0043 methodology, 'CO2 Utilization in Concrete Production', which will run from 10 July to 10 August 2026. The proposed updates, leading to version 2.0, broaden the scope to include additional optional project activities such as using supplementary cementitious materials and mineralising CO2 into recycled concrete aggregate. The revision also introduces new requirements for project-based calculations, updates the default cement displacement factor from 30% to 6.5%, and includes natural carbonation in emission reduction calculations. CarbonCure Technologies sponsored the methodology revision, with 3Degrees also contributing technically. This update aims to enhance the accuracy and applicability of carbon credit generation from CO2 use in concrete production.
