There are import corrected CO2 emissions data you can check if you care. Tl;Dr it's not as big as you think it is.
These are 3 relevant data sets from Our World in Data:
"Per capita consumption-based CO₂ emissions" (emissions adjusted for imports/exports)
https://ourworldindata.org/grapher/consumption-co2-per-capit...
"Imported or exported CO₂ emissions per capita" (shows the effects of imports/exports alone, as tons)
https://ourworldindata.org/grapher/imported-or-exported-co-e...
"Share of CO₂ emissions embedded in trade" (shows the effects of imports/exports alone, as percentage of total)
