You tell us how Canada, even if every single molecule of CO2 is  stopped in this country, could any meaningful impact on GHG's?  It can't.  That said, if you'd read my original post you'd recall that I made clear the greatest thing we can to do mitigate GHG rise is to STOP all coal-fired electricity production and replace it with Natural Gas, hydro, nuclear, wind and solar.

Even your pals at greenpeace say, "Burning coal is the biggest single source of carbon dioxide emissions from human activity". They are correct and there is loads of evidence to back that up.   We could meet world GHG reduction goals faster, cheaper and almost fully if we did that ONE thing. Stop coal fired power generation. 

Harming, punishing Canada's oil+gas industry will make no difference to world GHG balance.
