USA per capita CO2 emissions are large, but at least they have been coming down moderately fast. From 2007 to 2017, USA reduced emissions by 20%, whereas if we take Germany as an example of a country with strong "green" element in politics, Germany reduced by 8%.
Apply linear extrapolation, and USA would go below Germany in 20 years. Extrapolating with exponential decay, in 40 years.
