Verde Resources and Isometric are collaborating to certify engineered biochar used in BioAsphalt technology. The goal is to turn road infrastructure into long-term carbon sinks by locking carbon dioxide into asphalt, creating high-integrity carbon removal credits. Isometric provides the scientific protocols to ensure the carbon remains stored for 200 to 1,000 years. This approach allows infrastructure projects to be monitored and audited as verifiable carbon removal assets.

Verde is trying to turn roads into carbon sinks by mixing biochar into asphalt. They are teaming up with Isometric to make sure the credits actually mean something. Worth a look if you follow carbon removal in construction.
The key here is the durability quantification. If they can actually prove 200 plus years of storage in a road, the credit value jumps. I want to see the actual feedstock criteria they are using to avoid land use conflicts.
Putting carbon in roads sounds fine, but what happens during resurfacing or road repairs? If the biochar is dug up and processed, does the credit get reversed? The lifecycle accounting needs to cover the end of the road life.
Exactly. Road crews aren't known for careful carbon accounting. If the material properties of the asphalt change, it might affect how they mill the roads later. The cost of the engineered biochar also needs to be competitive with standard bitumen.
Interesting to see Isometric moving into the built environment. Most biochar credits are just soil application, which is harder to track. Roads are a fixed asset, which makes auditing simpler in theory.
