Active states
Five active Verra VCS projects, two carbon-removal pilots, and the only carbon credit methodology built from the ground up for cold recycling of US roads. Each project rehabilitates roads throughout the US, reusing the pavement in place instead of quarrying, heating, and hauling new material.

Four Steps, All On-Site, No Asphalt Plant
Every stage happens on-site using the existing pavement as the primary material. By eliminating quarrying, plant heating, and long-distance hauling, cold recycling delivers a faster, lower-carbon approach to road rehabilitation.
Failed Roads Qualify
Cold recycling is a reconstruction method, not a maintenance treatment. The road must have reached the end of its structural life, where resurfacing and repair are no longer effective solutions.
Mill and Remove Aged Asphalt
A cold recycler pulverizes the existing asphalt and base layers into loose material in a single pass. The failed road becomes the raw material for the new one, processed entirely on site.
Material Processed
The pulverized material is processed into a uniform, size and engineered mix.
Recycled and Remixed
A recycling agent is introduced into the reclaimed material, reactivating the old binder and transforming it into a structurally stable base layer without heat.
Compacted and Installed
The finished cold mix is laid right behind the recycling train and immediately compacted, allowing traffic to reopen within hours. It’s highly efficient: contractors typically finish 1 to 1.5 center line miles per shift, making it two to three times faster than conventional repaving.
Traditional Approach vs. the VM0039 Intervention
Compare conventional hot mix asphalt rehabilitation with ClimatePave's verified cold recycling methodology. By eliminating plant heating, reducing hauling, and reusing the existing pavement, VM0039 delivers lower emissions, lower costs, and longer-lasting infrastructure.

Cold Recycling vs. Conventional Hot Mix - Key Metrics
These key metrics highlight the measurable environmental, operational, and economic advantages of cold recycling compared with conventional hot mix asphalt rehabilitation.
01
Circularity
Cold recycling reuses up to 90% of the existing road in place, compared with the 20 to 25% typically recovered through conventional methods. This reduces demand for virgin aggregate and asphalt binder while diverting millions of tonnes of material from landfill.
02
Emission Reductions
Eliminating high-temperature asphalt production and reducing haulage cuts project emissions by up to 60%. Every reduction is measured using field data and independently verified under VM0039.
03
Air Quality
Removing the need for asphalt plants significantly reduces combustion emissions, volatile organic compounds (VOCs), and other pollutants associated with traditional paving operations, helping improve air quality around production sites and transport routes.
04
Reduced Pollution
Cold recycling avoids many of the pollutants generated during conventional asphalt production, including silica dust, diesel particulate matter, and hazardous solvent emissions, creating cleaner and healthier environments for surrounding communities.
05
Env. Justice
Asphalt production facilities are often located close to disadvantaged communities. By reducing reliance on asphalt plants and heavy haulage, cold recycling helps lower local exposure to industrial emissions and transport-related pollution.
06
Traffic & Safety
Processing materials directly on-site eliminates hundreds of truck movements per lane-mile, reducing congestion, improving road user safety, lowering noise levels, and allowing projects to be completed up to three times faster than conventional methods.
07
Cost Savings
Reusing existing materials reduces construction costs by 28 to 50%, helping transportation agencies extend budgets further while delivering long-lasting infrastructure improvements.
08
Preserved Structure
Rather than placing a new surface over deteriorated pavement, cold recycling rebuilds the structural foundation of the road. This extends pavement life, reduces future maintenance, and lowers the long-term environmental and financial cost of repeated interventions.
Why the Reductions Are Additional and Verified
Financial Additionality
Cold recycling competes against established HMA contractors who benefit from the status quo. A cold-recycling train costs roughly $6M, with additional operator training costs. Conventional HMA repaving yields an IRR above 34%, while investing in cold recycling reduces it to approximately 12.6%. Carbon finance closes that gap. Formal investment analysis under the UNFCCC CDM framework is available as a supporting attachment.
Common Practice
According to the NAPA 2023 survey, HMA and WMA account for ~98.5% of all US asphalt production. Cold in-place recycling (CIR) represents less than 0.4% of the market; FDR just over 1%. These technologies have been commercially available for decades yet adoption has not grown meaningfully, reflecting persistent structural barriers.
Regulatory Additionality
Cold recycling is not legally mandated by any federal, state, or local requirement applicable to the project sites. FSB and emulsion use remain discretionary engineering choices, not code-required practices.
Reversal Risk
Physical reversal risk is effectively zero. The reduction occurs at the point of production by avoiding fuel combustion and virgin-material processing. There is no carbon stock that can be re-released. No buffer pool or post-crediting monitoring for permanence is required.
