You're not actually looking at per capita emissions, you're looking at overall emissions. It isn't that the 1% to .1% are the biggest emitters, it's their emission levels multiplied by the size of the class.

Billionaires aren't the 1%, they're the 0.00003%.

Top 1% globally is basically anyone making more than $100k/yr.

If you deleted all billionaires from existence, it would make no impact on climate change. If you deleted all 1% ers and left the billionaires, there will be a huge improvement in climate changing emissions
