I wonder if there should be some scaling for extreme hot/cold countries. Most of our output here in Canada must be related to heating during our 6 months of cold climate.

Electricity and heat is indeed the largest sector by emissions in Canada (about a quarter) [1]. Though depends on where you are. In BC all electricity is hydropower, and if you have electric heating, your emissions are close to zero.

Transport is also about a quarter. So Canada can indeed cut emissions in half with present day tech by fixing these two sectors. Still a long way to go.

Also note that Estonia is at 7.3t, Finland 5.6t, Sweden 3.5t (Sweden was 8.6t in 1980). So climate is not really an excuse. It is just politics.

There’s lots of inefficiencies all around in Canada. Poor insulation, too much suburbanization, not enough heat pumps. Transportation is also very inefficient (not enough public transit, too much suburbanization, not enough rail).

Tar sands are an issue, as is other oil.
