For one, Canada isn't closing perfectly good nuclear plants prematurely. Germany could have saved a billion tons of CO2 emissions and billions of euros by just letting the last six plants run to their end of life.

Second, Canada didn't risk their whole industry on Russian pipeline gas, which everyone warned Germany against and now the worst case materialized with the Ukraine war.

Third, Germany is pumping in a huge amount of free carbon credits into the EU ETS. And Europeans don't get any benefit of the ETS fees.

The Canadian scheme directly kicks back part of the benefit to citizens, which makes it much more palatable

And fourth, the amount of subsidies that Germany is pouring into wind and solar energy just isn't sustainable. It's better to have carbon pricing and letting markets transition to low carbon energy, paid for by private capital.
