I think in that case you would have to say, as you said, it's guidance to the establishment of a standard.
My understanding is that the message here from the government is that it wants to do two things. It wants to make sure a standard is ambitious or is going in the right direction in terms of reducing greenhouse gas emissions, but at the same time it wants to make sure that it's balanced, that it will be possible for the industry with the technology that is coming up and so on to meet the standard. I think the message the government is sending is that you want to do two things. You want to have a standard that will help you reduce greenhouse gas emissions and tighten the fuel consumption standard, but at the same time you want to make sure the industry can do it, can have the technology to achieve the standard.
I think it's a balancing act. I would stop there.
