"Per capita basis" is meaningless for GHG emissions when a country, such as Canada, has few capitas. That is what the author of the article is saying.  It is deplorable that that Stephen Harper was too meek to come out of the closet and say outright what he thought about the whole Climate Change business. It is too late now. The country will be gravely harmed by our naive (but oh so good looking!) Mr. Trudeau. Only Donald J. Trump can save us rom ourselves!
