TED: How we could make carbon-negative concrete | Tom Schuler

The video discusses the widespread use of concrete and its environmental impact, particularly the CO2 emissions from cement production. It introduces a new cement chemistry that reduces CO2 emissions by up to 70% and eliminates water use. The new method involves curing concrete with CO2, making it stronger and more durable. The video also highlights the challenges of adopting this innovation in a traditional industry and explores future possibilities of making concrete a carbon sink.

In what ways does the new concrete technology contribute to water conservation?

Explain how the new concrete technology could potentially turn the concrete industry into a carbon sink.
