Yes. One thing that's very unfortunate, I think, looking back, is that before we ratified Kyoto there was quite a bit of modelling done around how to achieve our targets, and implications for employment were studied fairly closely in that period. A several-year gap has gone by since we did a serious matching up of what needs to be done to meet our climate change targets with the employment goals.
I think the point is, on balance, that those are positive, but there are pluses and minuses in that equation.
