What We Need To Do Now sets out a comprehensive programme of action to counter the threats to our environment. The book emphasises the importance, and relative simplicity, of decarbonising our energy supply but also stresses that this is a small part of the switch to a sustainable planet. Among many other urgent transitions, we also need to focus on changing the agricultural system and reducing our hugely wasteful use of resources. And, fundamentally, we need to ensure that the transition to a zero carbon world benefits the less well-off and reinvigorates the smaller cities and towns around the world that have been left behind. This is a practical, original and inspiring book: a new green deal for an inhabitable earth.
