In the revised and updated second edition of his 2005 book, Porritt extends his controversial argument that the only way to save the world from fuel shortages, climate change and environmental catastrophe is to embrace a new type of capitalism, and to do it quickly.

In this edition, Porritt also responds to critics with fresh evidence and suggestsa range of new actions, including in-depth coverage of the United States and the politics of climate change, the state of environmental debate and the massive upsurge in religious engagement with climate and the environment.

Porritt has also added new case studies to this edition, looking at the role of corporate giants like Wal -Mart and General Electric in a sustainable capitalist future. Porritt also looks in-depth at China and the global impact this economic giant may have as it grows into the most environmentally damaging -- or perhaps the first sustainable -- superpower of the 21st century.
