Carbon Negative Cement

[Nathanael]

The cement industry is a huge emitter of carbon dioxide. This post highlights two companies that have developed cement that not merely carbon neutral, but the cement actually absorbs carbon, making it carbon negative.

Check it out:


According to the EPA, the cement industry was responsible for 829 million metric tons of CO2 emissions, or approximately 3.4% of global emissions in 2000. Today, that number is reported to be as high as 5%.

The cement industry is also a major contributor to industrial process-related emissions and a product used in nearly all construction. In fact, annually, we use about 2.5 billion tons of the stuff.

Now, several companies are developing cement that is CO2 absorbing. That’s right, this cement is not just carbon neutral, it’s carbon negative.

California’s Calera Corporation is one of them, as is British start-up, Novacem, which just raised $1.7 million.
