TransAlta would strongly support the establishment of a regulatory framework. We believe that it is important to make progress, that certainty is critical for our decision-making. Since it is a long-term business, we need long-term certainty, so we are strong supporters of a regulatory framework.
As it relates to emissions trading, you're quite right that it is not required to have a viable emissions trading market. However, I believe that again it would cement certainty in the marketplace, which is important, especially in the early days of any emissions trading market.
So for that reason and for the benefits to the emissions trading, we would support a regulatory approach.
