I think governments should have ambitious public policy objectives, put it that way. I think that's the responsibility of government: to identify what the public policy objectives are and to make sure they're ambitious in any kind of measuring. We've got international agreements, for example, to adhere to. We've got all kinds of other things. Then I think the role of governments is basically to set the policy framework, as I tried to say before. After that, there is potentially a role for it in being a direct participant in R and D types of projects. There is, as has been highlighted before, a role for it in setting the regulatory framework and in exercising that regulatory framework.
I find it more difficult to find a role for government in setting the direction that industry should be moving in. Signals should come from governments; decisions should come from people who are close to the activities. In my view, the latter know better than somebody sitting in an office somewhere at a distance from all of this about what key decisions are to be made and what competitive advantages are to be exploited. That's my view.
