Check out Canada! I’m guessing the frigid climate and sheer size of the country translates to heavy-duty heating systems and much driving.
There’s not a one-on-one relationship between a country’ energy consumption and CO2 emissions, but the relationship is still pretty close:
Now for a comparison of the top country-level emitters and their per capita emissions:
