The term for this is "consumption based emissions." You can find charts for it at Our World In Data. Here's the chart for the US along with an explanation of the methodology:
The US is improving even after accounting for imports. Consumption-based emissions were 20.3 tons per capita in 1990 and peaked in 2005 at 22.7 tons per capita, declining to 14.9 tons per capita as of 2022. Of course present emissions per capita are not as low as if imports had no CO2 footprint.
Yeah. I believe the reason is rapid industrialization. As far as I’m aware that tends to be associated with high emissions. There is some hope that as African nations industrialize, they can use greener technology so we don’t see the same pattern repeat there. The population in Africa is nearly that of India and it’s growing rapidly.
