The impetus for sustainable development resulting from the Earth summit will have significant consequences in many areas of our national life. The Government are committed to reporting regularly on the progress that we make in following up the summit's conclusions.
The hon. Gentleman is right. That lies at the heart of the whole concept of sustainable development, and I welcome his support for the steps that we have taken.
Does my right hon. and learned Friend agree that any proposed carbon tax ought to be introduced world wide, rather than imposed on countries such as ours in isolation?
