Concrete and CO2

I was just blogging how much we like earthen floors because for one it doesn’t use CO2 producing concrete.

Then I decided to calculate how much CO2 your typical Brownstone basement would produce if you poured a concrete slab.

Answer: Almost ONE MILLION cubic feet of CO2 is let off to pour a simple brownstone basement concrete slab!

To pour a slab on a measly brownstone floor?!?!? Hey, we have to stop this act of ignorance.

Here is the math (disclaimer – I am not a genius at math):

For every tonne of concrete made there is a tonne of co2 gas put into the atmosphere.

One tonne covers 19,641 square feet of space! That is a lot of space.

Your typical brownstone basement requires cubic 16 yards of concrete if you are doing a 6″ slab.

One cubic yard of concrete will weigh 3.14 tonnes.

So…..your typical brownstone basement slab creates 3.14 tonnes x 16 yards  which is 50.24 tonnes of co2!

Multiply the tonnes of CO2 by the number of square feet in a tonne and that is an astounding 986,764 cubic feet of space.

Almost one million square feet of co2!!!

People, use earthen floors in your basement. They are just as good as concrete in so many ways and don’t create any CO2.

Here is an example of an earthen floor with a sacred design on it:
