In terms of the intensity targets, I agree with you that theoretically, if you ratchet up the levels of the intensity of reductions, you're going to get to the same outcome, but I'm not so sure that that's where we're headed.
What about the question of value-added and natural gas? What sorts of market signals do we need to make sure we're getting the highest and best use out of our natural gas resources?
