I'd be interested in hearing your take on combining economy and environment. There's a dichotomy there that tends to get separated. All too often the economy is separate from the environment, and we either have to be good for the economy or we have to be good for the environment. I think the view people are taking more and more these days is that one obviously can't be strong without the other also being strong, particularly when it starts to take a long-term perspective. I'd be interested in your reflection on that.
Perhaps, since your taxation expertise is significant, you could give a little overview of your feelings on consumption taxes versus carbon taxes versus income taxes as tools to deal with environmental issues.
