Who cares about Canada's paltry 1.6% contribution to world CO2 emissions? Even if cutting this back to 1.2% would make any difference to the climate, which it won't, the US will be totally ignoring the Paris "Agreement", and their contribution is 10 times ours. And China, at 30% currently, only commits to peaking its emissions by 2030. Forget about it - it is a total waste of our money.
