Yes, I did use a very general term, “market failures”. Maybe I could just expand on that a little. There are various scenarios in which carbon pricing on its own either won't work or won't work fast enough. It's for that reason that the pan-Canadian framework also includes regulations and financial incentives for innovation. I'll give you a few examples.
One very straightforward one that the chair will be familiar with is that carbon pricing can only work when it's imposed on something we can measure accurately and systematically. It's for that reason that we don't impose carbon pricing on methane emissions from livestock. We know it happens. There's no generally accepted way to measure, monitor, report, and attribute it to an individual farmer. There's no system and there's no way to use carbon pricing to address that kind of issue. You need a different kind of measure to create an incentive to reduce that kind of emission. That's one area where, with the market itself—and maybe “market failure” is not the right term—the use of a carbon price wouldn't work.
At the other extreme, an example of emissions we absolutely know about and can measure are emissions from electricity generation facilities that are coal-fired. We know those are major contributors to greenhouse gas, but we also know that investments in electricity generation facilities cost tens of millions of dollars and have a capital lifespan of decades. To ensure that no further investments are made in coal-fired electricity generation, rather than rely on a price signal that would increase over time and that may or may not deter future investment, the government chose, in addition to carbon pricing, to also regulate those facilities. This would provide clear direction to the Canadian economy and to provincial governments and others that might invest in electricity generation that certain types of investments will no longer be allowed, regardless of what the prevailing carbon price would be.
On your question as to whether there are industries that might be adversely affected, the position of the government is not that a carbon price—and I'm going to use a double negative—should not be imposed on those facilities, but rather that those kinds of considerations are more realistically to be considered regional industrial policy and can be best dealt with by means of decisions that provincial governments can make about carbon pricing revenue return. As an intermediary policy, the government has also put in place various financial programs that can be used, among other things, to, for example, enable industry to invest in energy efficiency or in low carbon technology to enable them to minimize their exposure to a carbon price.
I hope that answered your question at least in part.
