The price of carbon emissions does need to go up for carbon capture and storage to make sense. It probably needs to be somewhere in the order of $100 a tonne because of the costs of doing carbon capture. For the industries, for example, the power industry in Alberta, the consumer in Alberta will end up paying for the carbon capture and storage because the cost of electricity will be higher, and the extent to which the price of electricity is higher is partially related to the investment tax credit. If the investment tax credit was lower, the price of electricity just needs to go up further in order to justify the carbon capture and storage. The calculation on how to figure out the rate of return on the invested capital is not a very complex calculation.
I want to emphasize the point that many of these projects require billions of dollars of capital, so investors are rightly asking how durable the carbon tax is.
