Concrete is responsible for nearly 10% of global carbon emissions. CarbonBuilt is changing that.

Our Carbon XPRIZE-winning technology reduces concrete’s carbon footprint by 70% to over 100%. We can do this without compromising product performance or plant operations — and our blocks don’t cost more to make.

Take a walk through our first plant: Blair Block

In just a few minutes, you’ll see how we solve concrete’s carbon problem from two sides. First, we remove carbon-intensive portland cement from the mix and replace it with a proprietary low-cost alternative made from widely-available low carbon materials. Then, we cure it at ambient pressure, to harden the concrete and store the CO2 permanently.
