The problems that the world faces - from nuclear proliferation to climate change - can't be tackled by the West alone. They need a coalition of not just West and East, but they need a coalition of Christian and Jew and Muslim.

Dangerous climate change... It's important not to be alarmist but it is very important to be alarmed

We know from history that the way wars are concluded is absolutely the key to whether or not there is any peace to be kept.

Turning every business into an environmental industry will involve applying new principles...first, we need to make more with less...second, we need to design out waste...third, we must begin to decarbonise our energy supply

I'm a great believer in the Arsene Wenger school of management - which is, you don't worry about the opposition, you just get your own act together.

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
