Concrete is all around us: we use it to build our roads, buildings, bridges and much more. Yet over the last 2,000 years, the art of mixing cement and using it to bind concrete hasn't changed very much -- and it remains one of the world's biggest emitters of carbon. Entrepreneur Tom Schuler previews an innovative way to create concrete, potentially turning it into a carbon sink that traps CO2 from the atmosphere -- while producing a viable building material.

Tom Schuler: How we could make carbon-negative concrete

How we could make carbon-negative concrete

Innovative cement chemistry could slash CO2 emissions by 30%, turning the concrete industry into a potential carbon sink.

Concrete cured with CO2 not only locks away carbon but also saves trillions of liters of water, revolutionizing construction.

A breakthrough in concrete technology may enable roads to consume more CO2 than 100,000 trees annually, redefining sustainability.
