There are over 2,605,331 miles of paved road in the United States

When combined with the heat released by vehicle engines, paved areas can boost the temperature in cities by as much as 22°F, according to the Environmental Protection Agency.
The number of urban dwellers worldwide is rising by as much as 78 million people annually, according to the United Nations Population Division. That’s the equivalent of adding nine New York Cities to the planet every single year.

More than 4 billion tons of cement were produced in 2021, contributing 8% of global CO2 emissions, according to think tank Chatham House.
So while all you try to fix CO2 emissions with EVs you will still need concrete and the net effect of how that increases "climate change" is yet to be seen.
My whole point of this post is simple...
why are we so worried about 422 ppm CO2 when 1/2 billion years ago the world was living successfully at 7,000 PPM!
Some 500 million years ago, when the number of living things in the oceans exploded and creatures first stepped on land, the ancient atmosphere happened to be rich with about 7,000 ppm of carbon dioxide. "

posted on November 1, 2017 The United States has a lot of roads—3,980,817 miles to be exact. Roads are relatively simple but make a big impact, and they exist nearly everywhere…

Feeling the Heat? Blame Concrete
There's a good case to be made that we should stop using concrete in our cities—if only we had another option.

How the World Passed a Carbon Threshold and Why It Matters
Last year marked the first time in several million years that atmospheric concentrations of CO2 passed 400 parts per million. By looking at what Earth’s climate was like in previous eras of high CO2 levels, scientists are getting a sobering picture of where we are headed.
