When we think of things that release carbon dioxide into the atmosphere, we often imagine cars and factories. But a huge emitter of CO2 that's often overlooked is cement.
For every metric ton of cement produced, there's an equal amount of CO2 that's released into the atmosphere. Every year, more than 4 billion metric tons of cement are produced, accounting for around 8% of global carbon dioxide emissions. To put that in context, if the cement industry were a country, it would be the third-largest emitter of CO2 in the world.
"Cement is kind of the glue that holds concrete together, and concrete is used more than any other material on the planet other than water," said Tom Schuler, President and CEO ofSince 2007, Schuler and his team have been working to create a green cement to reduce the amount of CO2 the material releases into the environment.
"When you make Solidia cement, we are cutting the CO2 emissions at least by 30%," said Vahit Atakan, chief science officer at Solidia. "And when we cure Solidia cement, when we make the concrete, we add an additional 20, 30% of CO2, we consume it during curing. So this adds up to 50, 60%. And depending on the formulations, our CO2 savings can go up to 70%."

if everyone who made/laid the concrete bought a battery powered car, then 'no harm -- no foul'.....
lets please eliminate all the CO2, this is what the left want, before they think as usual, eliminate CO2, which will eliminate plants, which will eliminate humans. FYI, CO2 has been at higher levels before in Earths lifetime, several times.
slimdogmike An interesting report, perhaps Graphene added to concrete would produce a better result.
Are humans a huge emitter of CO2?
So do mouth-breathers
Let's all just live in caves again.
Yes, I knew. A lot of people know
And did you know that CO2 as a factor in ClimateChange is tiny and of no significance? I bet you didn't!! This talk to the Canadian Senate in 2011 is only 15 minutes long and tells it as it is - a MUST SEE
Sigh
News Flash; There’s no Free Lunch
rgay
We should outlaw concrete
So Trump should be attacking them any day now.
