It's not just the price of carbon today that is driving investment, but the expected price of carbon and the value of credits into the future. These are long-lived projects, and as a result, their costs or their revenues are going to extend across the life of the project, pending the existence of carbon pricing, pending the reliability and robustness of these credit markets that it creates. The uncertainty is hugely important for driving that investment and making those projects bankable. It depends on the existence of the policy, as well as the robustness of those credit markets.
