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.

We are living as if we had three planets' worth of resources to live with rather than just one. We need to cut by about two-thirds our ecological footprint. For that we need one planet farming as well as one planet living - one planet farming which minimises the impact on the environment of food production and consumption, and which maximises its contribution to renewal of the natural environment

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

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

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.

The window of opportunity to avoid dangerous climate change is closing more quickly than previously thought.

And the truth is, those who are terrorists only have to succeed once, and those of us who are trying to build an inclusive society have to succeed every time.
