but event "emissions" isn't a simple calculation No one is claiming that it is, but there are standardised reporting practices to ensure proper coverage of emissions when published. These are the Scopes 1, 2, and 3 (which includes 12 sub-scopes), listed in the Greenhouse Gas Protocol. They are the GAAP of the sustainability industry and is required by every major reporting mechanism (e.g. CDP, etc).

All the items you listed are covered within the scopes, include power generation, fuel processing (typically called well-to-tank), transmission loss, emissions embodied in purchased assets (e.g. construction emissions of a vehicle), employee commuting, waste, etc.

Depending on how you look at something, getting an electric car is a horrible thing to do. Even then, is that better or worse than charging it at night from a coal power plant? A common claim by climate-deniers that has been widely debunked for almost every power network in the rich world (where electric cars are most common). If I remember correctly, only two countries in all of Europe were found to have lower emissions with a petrol engine than plugging into a dirty grid.

I think a lot of the woke efforts in and of themselves are short sighted, and not very well thought out at all though. Woke? Not thought through? You wrote a long comment about carbon reporting when you clearly don't know the first thing about how carbon is reported or calculated...
