A 3°C world has no safe place

I don't think those figures are right - 5.3T/7.5T would mean 70% of CO2 in the US is caused by coal-fired power plants. According to the EPA data for 2019 [1], power generation accounted for 25% of greenhouse gas emissions, and 62% of that was fossil fuels ("mostly coal and natural gas") - so that means fossil fuels for electricity accounted for 16% of the greenhouse gas emissions. The EPA report shows transportation as the largest source, at 29%

Their figures also suggest CO2 emissions were 20T pp in the US in 2019! (6558MT of CO2, 328.2M population)

The reason I'm so struck by the coal-fired electricity production numbers are that this seems VASTLY easier to fix than the transportation numbers. Even if the latter would have more impact, I think we're still a long way from being able to dramatically affect that, whereas ramping up renewable electricity generation and ramping down fossil fuels seems like a (relatively) simple challenge.

Yeah, add it to the long list of things we're just not doing :-( nuclear could have made a significant dent in CO2 from base load generation, but we didn't fund work into safer nuclear generation so we're stuck with fairly limited options for base load now

Just edited it. I missed the 1 from the 17.

My source was

http://www.ecocivilization.info/three-tons-carbon-dioxide-pe...

which I think is from about 2017 (and has several citations at the end).
