Alberta ground zero for green battle

Former Alberta Premier Peter Lougheed warns of an imminent constitutional battle over the environment.

 "On one side is the Canadian public, deeply worried about climate
change, putting pressure on the federal government for strong
environmental protection legislation that will lead to reduced
greenhouse gas emissions.

On the other side is the province of
Alberta, which has constitutional power over its non-renewable
resources, including the oilsands around Fort McMurray, which have been
dubbed "Alberta's Runaway Train" because they are the fastest-growing
source of greenhouse emissions in the country."
