Substanceless, like the woman who released the report.

It’s impossible for Canadians to assess the effectiveness of Prime Minister Justin Trudeau’s national carbon pricing plan when his government is pulling numbers out of a hat, making highly suspicious claims about its effectiveness.

A report released Monday by Environment Minister Catherine McKenna predicts Trudeau’s carbon price could come close to meeting Canada’s 2020 and 2030 industrial greenhouse gas emissions reduction targets, submitted to the United Nations.

But it is so flimsy, it appears to be an attempt by the Liberals to put a fig leaf over the recent political embarrassment Trudeau and McKenna suffered when they refused to say how many tonnes of emissions the PM’s $50 per tonne carbon price would eliminate by 2022.
