While we reduce our own carbon footprint we will encourage the companies who truck our DVDs and newspapers, sell us paper, and provide an enormous range of products and services to all contribute.

We need to push ourselves to make as many reductions as possible in our own energy use first - and that takes time. But we must do this quickly - the climate will not wait for us.

Why would I spend $5 billion for something in order to wreck it?

The world is changing very fast. Big will not beat small anymore. It will be the fast beating the slow.

We could make a difference just by holding our emissions steady as our businesses continue to grow. But that doesn't seem to be enough: we want to go all the way to zero... Today, I am announcing our intention to be carbon neutral, across all our businesses, by 2010.

So long as I can stay mentally alert - inquiring, curious - I want to keep going. I love my wife and my children, but I don't want to sit around at home with them. We go on safaris and things like that. I can do that for a couple of weeks a year. I'm just not ready to stop, to die.
