VIDEO | A concrete idea to reduce carbon emissions

Karen Scrivener | TED Countdown

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.

This talk was presented at an official TED conference, and was featured by our editors on the home page.
