Earlier this year, Sara Law of the Carbon Disclosure Project raised her hand at a conference in New York on government and private sector initiatives to address climate change. She politely asked the panel, which had been assembled to discuss opportunities for investing in low-carbon infrastructure, whether they knew how much cement each project might require. The panel members shifted uncomfortably in their seats and chuckled; no one jumped in immediately to respond.
The problem is that many of these projects require concrete. A lot of concrete. This worries Law and her colleagues at the Carbon Disclosure Project, a non-profit that tracks industrial greenhouse-gas emissions and promotes proper carbon disclosure. The CDP recently released a report, “Building Pressure: Which cement companies will be left behind in the low-carbon transition,” warning the cement industry — cement being the main binder in concrete — that “in its current form, it will not be compatible with” any nation’s commitment in the Paris agreement; and if radical changes do not occur the world will “risk missing [its] climate goals.”

Sacre bleu. What will gay paree say? ;-)
Natural gas is regulated some places. Texas, California and other states do. But some states are very lax and the authority to regulate that on private land falls to the states. Obama implemented regs on federal lands where he had the authority, but Trump undid it.
How about sulfur?
They determined long ago that the sulfur in coal caused acid rain and global cooling so they shifted to low sulfur coal and Congress amended the Clean Air Act to regulate sulfur. Coal fired Power plants are allowed emit up to 100 tons per year of sulfur.
Along with sulfur, Congress included mercury, arsenic and other metals but that has never been implemented at the national level. But some states regulate mercury at 50 tons per year.
CO2 is not massively targeted.
Only the largest emitters are targeted. There are many sources of CO2 that are not and will not be regulated. Obama's first set of CO2 regs that he implemented in 2010 and were approved by SCOTUS in 2014 which applied to new and expanded permits affected only steel mills, cement kilns, and power plants. New permits had regulatory threshold of 100,000 tons per year of CO2. Expanded permits were at 75,000 tons/yr.
Obama's second set of CO2 regs that applied to existing permits and was called the Clean Power Plan and is still in court. It applied only to power plants.
Otherwise, the other large source of CO2 was auto and light duty truck tail pipes which were to be reduced by rising CAFE stds
There are no boring pollutants and many are regulated. The smog gasses which are NOx and VOCs are regulated at 250 tons/yr. Ozone it self is regulated at 75 ppm and if your locale exceeds that, you have to get your tailpipe tested. Chloro, Flouro, CFCs are regulated. There is a big long list of chemicals that was regulated in the 70s and congress expanded that list recently
CO2 is part of the desired outcome....
Of
“During complete combustion carbon and hydrogen combine with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). During incomplete combustion part of the carbon is not completely oxidized producing soot or carbon monoxide (CO).”
We baby boomers learned this 7th grade science.....
There is a lot of other stuff in coal besides carbon. Did they teach that to you in Podunk?
That's what I was thinking. And maybe some grass huts. A cave here and there, maybe a nice mud hovel. And we could call it "progress."
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!
Excellent! By the way, I clicked through to the original study the article is “reporting” on and it clearly says cement is responsible for 6% of carbon emissions.
So perhaps in the common core 6/100 reduces to 1/3.
The point was made in reference to automobile CAFE standards to reduce CO2.
No effort was made on my part to discuss other combustion by products. Just the demonized carbon dioxide.
Silly little man..
These people need to be thrown into a deeply excavated footing and covered with a LOT of concrete.
Let’s just see how Social Justice Sarah enjoys living with a primitive and unsound infrastructure.
ARE WE STUCK WITH CEMENT?
What do you call 10,000 “environmentalists” up to their necks in concrete?
A good start.
Pozzolan provides an alternative for the Portland process. Use of fly-ash in modern mixtures is an attempt to gain attributes of volcanic ash as applied in Roman cement, which is very resistant to salt water.

Pumice found to be the best cement material for sealing nuclear material storage/ containment vaults which have cracks. Made in USA—sourced from Idaho!

There is a substitute. Volcanic ash. The Romans used it and their concrete has lasted for thousands of years. Modern concrete doesn't last more than a couple of hundred years.
Here is a point of trivia. We spent millions of dollars trying to replicate the formula of Roman concrete. Well, we figured it. How? Marcus Vitruvius Pollio, an engineer for Octavian, who became Emperor Augustus wrote it down.
The cement plant in Charlevoix Michigan when I moved there in 1976 was named, appropriately enough, Medusa Cement.
