Can Green Cement Reduce Global Warming?

Carbon dioxide is probably the greatest issue with global warming. As it stays in the atmosphere for a really long time, up to a couple hundred of years, it is an issue that needs to be addressed. For the future health of our planet, could green cement help the reduction of carbon dioxide emissions?

CO2, or carbon dioxide, is one of the many greenhouse gasses that trap heat from the sun. While some are natural and necessary, like water vapor, others are becoming too potent.

Green Cement Changes Fight in Global Warming

Typical cement creates a lot of carbon dioxide during production. For every ton of cement, a ton of carbon dioxide is released into the atmosphere. That's a 1:1 ratio.

Brent Constantz, has figured out how to create a green cement to help with the problem. In an effort to reduce the large amounts of carbon dioxide emitted, Constantz is looking for venture capitalists to make his dream a reality.

He wants to "repair the world."

From SFGate.com:

Back when Stanford Professor Brent Constantz was 27 he created a high-tech cement that revolutionized bone fracture repair in hospitals worldwide. People who might have died from the complications of breaking their hips lived. Fractured wrists became good as new.

Now, 22 years later, he wants to repair the world.

Constantz says he has invented a green cement that could eliminate the huge amounts of carbon dioxide spewed into the atmosphere by the manufacturers of the everyday cement used in concrete for buildings, roadways and bridges.
