Here's what everyone seems to be missing in the PBO's climate policy math - 2019-06-15
Canada's greenhouse gas emissions are projected to decline to 592 megatonnes by 2030 — a significant reduction, but still 79 megatonnes above the target to which this country has committed. In the interests of framing future policy actions, the PBO estimated the sort of additional carbon levy that might be needed to eliminate those remaining megatonnes.
According to the PBO, that new carbon tax, applied broadly, could start at $6 per tonne in 2023 and rise to $52 per tonne by 2030.
The Conservatives were, perhaps predictably, aghast at the suggestion. But that puts Andrew Scheer's Conservative opposition in the odd position of complaining about the cost of meeting an international target that was first established by Stephen Harper's Conservative government — a government in which several of Scheer's frontbenchers were cabinet ministers.
