Direct statements from DOT and municipal partners - each tagged to its VCS project

"The ClimatePave program gave us a legitimate way to report carbon outcomes on projects we were already doing. No additional cost, just documentation and a revenue share we didn't expect."

Director of Public Works • New York County DOT • VCS 3616

"Finding out our cold recycling projects produced verified carbon credits was a surprise. Our county board loved reporting the co-benefits to constituents."

County Highway Superintendent • Massachusetts DPW • VCS 3094

"After reviewing the VM0039 methodology and the Verra audit reports, the accounting is rigorous. These are real, measurable reductions, not tree-planting."

State DOT Pavement Engineer • Minnesota DOT • VCS 4546
