First of all, we have to say loud and clear to all those who are engaged in the fighting that attention to and respect for humanitarian needs is absolutely imperative. Anyone with any knowledge of Iraq, never mind any concern about the future, knows that the way in which the war is prosecuted has a big impact on what comes afterwards.

My advice is very simple: if you can win a small battle, it gives you confidence in the political process to take on bigger battles, and so it is very much a bottom-up grass-roots way of doing politics.

In the future, every industry should be an environmental industry. In a world where energy and carbon emissions are constrained, every business must take resource productivity seriously

The clearest evidence that we are living beyond environmental means is the threat of dangerous climate change. The scale of this threat, to human life and to the natural resources and assets on which it depends, for everything from oxygen and clean water to healthy soils and flood defence, means that this simply must be our top priority

John Major put the 'er' back into Conservative, David Cameron's put the Con into Conservative - and Norman Lamont put the VAT into Conservative!

Today, the UK must be the pioneer of a new model of economic change, that integrates social and environmental consideration. This is not just a question of values and moral duty. It is about our economy's capacity to sustain itself

Essentially, by 2050 we need all activities outside agriculture to be near zero carbon emitting if we are to stop carbon dioxide levels in the atmosphere growing
