The wedding ring on my left hand was bought by my grandfather, Samuel Miliband, in Brussels in 1920. I never knew him, as he died when I was one. But his ring was kept by my aunt until it was placed on my finger by my wife Louise 32 years later.

Thirty years ago, if you said the country was living beyond its means, people would have thought about economics. Now, if you talk about the country, or the planet living beyond its means, you think about the environment. We are taking out more than we are giving back. We are consuming energy, water, and other natural resources in a way that is leading to huge and often irreversible damage to the planet. So too are most other developed nations. And so too will China and India if they follow the same path of economic development as us

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

Everything about my politics has been about the future.

What's now urgently needed [to stop environmental disaster] is the international political commitment to take action to avoid dangerous climate change.
