Just read a great article from @The Brawl Street Journal where a German research institute shows clearly that the green claims about EVs depend a lot on where they are made and the CO2 content embedded in the car. For instance, China’s CO2 generated per ton steel is ~ 2.5X that of European steel. Once again, the reason that many things from China are cheap is that they generate the pollution over there, but in the case of global CO2, it comes back in the end. See Brawl Street Journal recent post entitled “Autosterben”.

One of my favorite examples of technological innovation rather than government regulation leading to environmental improvement is the steel industry’s transition from charcoal to coking coal to make steel.

That only happened because the thermodynamics of blast furnaces improved the larger they got. The reason being that the increase in volume was a cubic function whereas the increase in surface area driving thermal losses was only a squared function.

Without this change there would have been practically no forests left in North America by now.

Without regard to spending more money to improve the technology used to save people from environmental harms, I am all for it.

But the level of carbon dioxide emissions drives the harm done to every other living thing on the planet as in the acidification of the ocean, the severity of droughts, etc.

Thinking we will be fine while the rest of the natural world goes down the drain is not particularly plausible.
