I'm afraid I'm going to repeat myself, and I'll elaborate a bit. The impacts depend, first of all, on the direct impact of the carbon charge on commodities that the household purchases, such as gasoline.
Second, the impact also depends on the cost of goods that are produced by large industries that will not be subject to a carbon charge, but will be subject to the output-based pricing system that will relieve those industries of a significant portion of the carbon charge on their emissions. It will charge them on the margin of their emissions. While we have laid out the authorities for that system in the bill and have published a number of papers proposing an overall approach to that system, we're in the middle of consultations to develop the actual standards that will be the heart of the output-based pricing system. They will actually determine the impact on the price of commodities and goods made by those industries. We don't know the details of that yet.
Third, again, the impact depends very significantly on the way that revenues are returned. We know that in other jurisdictions, in jurisdictions that have pricing, in some cases household costs are completely covered. Alberta estimates a direct impact on households ranging from about $280 to $500, and they've committed to returning all of those direct costs to about 60% of households in Alberta, so it's tailored to low-income versus high-income—
