3 tons per capita per year, globally, is 24 gigatons — that would only be a 30% or so reduction from the status quo.
We need a 99.9% reduction to be long-term sustainable; that's 4375 grams of CO2 per person per year. If there was no carbon capture, it would be at the level of "everything everywhere except for North Korea" or "everything in every country except for land-use changes to grasslands"
Thinking of simplification, France is ~70% nuclear electricity, which I emphasise because I'd already noted a roughly 10x gap between worldwide electrical and worldwide all-forms power.
