They will then realise, as we have with the financial crisis, that we are up against the wall and hitting the buffers and we have got to change.

We have an overdraft with the earth something in excess of 130 per cent. We currently consume something like 30 per cent over and above what we are replacing and rather like an overdraft at a bank that can't go on.

Forward thinking companies that adapt positively to the sustainable business agenda will be at the forefront of resource productivity, reducing waste and of environmental reporting. They and their management teams make things happen ahead of their competitors

Globally, emissions may have to be reduced, the scientists are telling us, by as much as 60% or 70%, with developed countries likely to have to make even bigger cuts if we're going to allow the developing world to have their share of growing industrial prosperity...The Kyoto Protocol is only the first rather modest step. Much, much deeper emission reductions will be needed in future. The political implications are mind-blowing.
