Is it enough? Aren't these changes being more than offset by increased emissions elsewhere?

> Deindustrialization of the West led to improvements in ecology as well, I imagine.

It seems doubtful, since production didn't stop but simply moved to other places, often with much looser regulatory regimes.

Car emissions are dwarfed by industrial and agricultural emissions. Plus, before an electric car is used for the first time, it already generated more carbon than the dirtiest of non-electric cars during its manufacturing.

Then, if factories move from one country to another, with a higher carbon footprint, the global emissions don't go down. You are just moving [while increasing] emissions to somewhere else.

So, the "cleaner environment" is just a local phenomenon and a global level it is not the case.
