I found out that there is approximately .035% carbon in the atmoshere on a molar basis. -Universiy of Michigan

I calculated the amount of carbon in the atmosphere and got 2,730.8 Gigatons. I got the mass of the atmosphere from the Handbook of Chemistry and Physics. I calculated the mass percent of carbon in the atmosphere and multiplied the two numbers.

I found out that 9 million metric tons of carbon dioxide were produced during cement production in 1993. -Energy Information Administration

I found out that 100 million tons of carbon dioxide are emitted into the atmosphere each year from cement production. -Greenhouse Gas Online

Carbon dioxide emissions from cement production are estimated at 560 million tons per year. -Information Unit on Climate Change

Interesting facts:cement prodution is the third largest cause of man-made carbon dioxide emissions. While fossil combustion and deforestation produce a significantly larger amount of carbon dioxide, cement production accounts for 2.5% of total worldwide emissions from industrial sources. -Information Unit on Climate Change
