CarbiCrete, a Canadian company that makes concrete blocks without cement, has been selected by the Government of Canada as a low-carbon construction solution. Their process uses steel slag instead of cement and captures CO2 from industrial sources to cure the blocks, permanently storing the carbon. This is a practical example of carbon utilization in a high-emissions sector. The selection means CarbiCrete's technology may be used in federal building projects, giving the company a direct path to scale. Concrete production accounts for roughly 8% of global CO2 emissions, so alternatives that eliminate cement and store carbon could have a significant impact if deployed widely. The government backing adds credibility and potential procurement demand. Still, the announcement lacks specific details on volume, timeline, or funding. It is a selection, not a contract. For the carbon credit community, the interesting angle is whether this leads to verified carbon removal credits from the CO2 permanently stored in the concrete, and how the accounting for that would work.
