Yes, I'd like to comment on this point too, and really go back to several of the comments I made before.
On this problem of climate change, we have to get the economy working for us rather than against us. It seems to me that this is really the job of the legislative regime, right?
Clearly, no single company wants to take a leadership position on this issue. It's a matter of competitive disadvantage. That's why a legislative regime that encourages mandatory efforts to work toward a less carbon-rich development regime is absolutely crucial.
We can't expect our companies, as individual companies, to take a leadership position in this, because they'll see themselves to be at an enormous competitive disadvantage. We have to make a regime that levels the playing field and makes it possible for them to compete on that playing field, to our collective advantage.
