According to the CDP report, the cement industry is the second-largest industrial emitter of carbon after the steel industry. And when accounting for its use in human-made structures, it is responsible for more than a third of the world’s carbon emissions.

This shows the complete and utter lack of critical thinking that befalls anyone who writes about climate change. Did this writer turn off his or her brain completely before typing that last sentence?

If cement accounts for 1/3 of all carbon emissions and it's less than steel, then that means that cement and steel alone account for at least 2/3 of all emissions, which would mean that everything else in the whole world put together (oil, coal, natural gas ... all energy) would be less than 1/3rd. OR the author thinks that all the various sources of carbon emissions add up to some number much greater than 100%.

Major error in you post. You assumed there was brain activity involved.

OR the author thinks that all the various sources of carbon emissions add up to some number much greater than 100%.

1/3 due top Cement
1/3 due to Steel and other metals
3/4 caused by Automobiles and Trucks
1/2 is caused by Humans exhaling
1/3 is caused by outdoor bbq’s and firepits
2/3 is caused by Power Plants

If you would have passed your common core exit exam in high school you would know all these add up to 100%.

I am old and we didn’t have common core back then, but it looks exciting!
