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.
This talk was part of the Countdown Global Launch on 10.10.2020. (Watch the full event here: https://youtu.be/5dVcn8NjbwY.) Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world. Get involved at https://countdown.ted.com/sign-up
