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.

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

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

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
