CarbonBuilt produces ultra-low carbon concrete masonry and hardscapes, reducing the carbon footprint of our products by >70%. We do this by replacing much of concrete's cement ingredient with Reversa, our upcycled low-carbon cement replacement made from industrial byproduct materials, and investing holistically in the plants we own to reduce waste, cement, and CO2. We are producers ourselves -- in February 2025 we bought a family-owned concrete masonry plant in CT and have now deeply decarbonized it as we scout for future acquisitions. We also distribute Reversa to other concrete masonry producers to support their decarbonization goals. We have enabled the production of >50,000 tons of ultra-low carbon CMU since our commercial debut in mid-2023, reducing >2,500 tCO2. We intend to continue buying masonry plants and pushing the boundaries of CO2 reductions in plants that we own. Our EPD is already the lowest-carbon CMU in the USA.
