Let me start with the comment you made at the beginning, which was about using 2005. The base year that the Paris Agreement uses is 2005, so every country around the world uses it, but we have seen significant reductions since 2015 as well.
In terms of the carbon price—and we've had this discussion in the House of Commons many times—eight out of 10 families actually get more money back. It works directly inverse to income, so people who live on the most modest incomes get the most money back. This is something that more than 300 economists have weighed in on, including Trevor Toombs from the University of Calgary and Brett Dolter from the University of Regina.
It is an affordability mechanism, but it is also effective in addressing the climate crisis. In 2030, we'll be at about half of the emissions reductions, so will it address the impacts of climate change? Yes, over time, it will, just as deploying electric vehicles, deploying carbon capture and sequestration and improving energy efficiency will all have an impact on reducing the impacts of climate change.
