Yes, absolutely. For the question as to whether or not it should be financial instruments or commanded patrol, my answer would be that it eventually will be both.
What we're talking about here is anticipating that at some point in time there will be indeed regulations, there will be a carbon-constrained future that we will all be operating in. This is an anticipatory move that we are attempting to make. We want to be able to develop, before we get to that point, the ability to in fact move to a more carbon-neutral approach, particularly in the regions where they don't have other options.
