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.
Concrete is the second most-used substance on Earth (behind water), and it's responsible for eight percent of the world's carbon footprint. Cement researcher Karen Scrivener shares the research behind a pioneering new kind of cement known as LC3, which could slash carbon emissions from this crucial building material by 40 percent, if adopted at scale.
