The output-based pricing system will require some sort of analysis and information for each specific firm that is being regulated under an output-based pricing system. That requires a whole information-gathering effort and technical analysis validation. There are a number of steps in that process.
With absolute emissions trading systems, yes, there are complications. Firms need to be able to measure their inventory's greenhouse gas emissions, but we've been developing these capacities and practices over a decade in Quebec, and I think that probably most firms across Canada have already developed these capacities. There is a standardized process, whereas each output-based pricing system seems to have its own specific rules and regulations about how to calculate the thresholds and how to measure compliance, which become very complex.
