Madam Speaker, the member is actually wrong. The University of Ottawa did a study of the impact of the public transit tax credit and found that the decrease in greenhouse gas emissions was marginal and ended up costing the Canadian taxpayer, which the member purports all the time to be defending, $1,000 per tonne of greenhouse emissions reduced. The current price of carbon is about $20, going up to $50 by 2022. This is, of course, scandalous to the member, yet his government spent $1,000 per tonne to reduce greenhouse gas emissions with an ineffective credit.
This has been borne out by studies especially at the University of Ottawa. A price on carbon does work because the demand curve is downward sloping. This is economics 101. Prices and demand go in opposite directions. The track record in B.C. proves that through a price on carbon we can reduce greenhouse gas emissions by quite an amount.
