You may want to take another look at that list. Proudly declaring you’re only the 16th worst per-capita (already very high!) when ahead of you are tiny places like Pulau, New Caledonia, Gibraltar and Curacao is really quite funny.
Facts are neutral, when someone says something incorrect it’s worth pointing out the truth.
UAE, Saudi Arabia, Canada, Russia, and Australia are mid sized countries that emit more CO2 than the US per capita but you need to come up with a new metric to get that list. CO2 emissions by countries with more than 10m people or whatever. Perhaps bump it to countries with over 100m people so America is #2 on a list of 16 countries, or 300m so America is #1 on a list of 3 countries.
