With over 56% of the BC popular vote going to the two anti-pipeline parties compared to 41% for Christy Clark's Liberals, it is a real stretch for AB Premier Rachel Notley to claim social licence for the Kinder Morgan pipeline expansion.
Notley certainly does not have scientific license to build pipelines.
Notley's climate/pipeline rhetoric is completely divorced from reality.

Why would a tiny carbon tax in conjunction with a huge boost in oilsands emissions buy social license?
Social licence is something you receive from affected citizens, communities, and stakeholders.
Social licence is not something governments can award themselves.
Carbon taxes do not constitute social license for pipelines any more than rehab constitutes license for a stiff drink.
