The book is divided into three sections. The first part, Meeting the Challenges of the Anthropocene: Back to planning? identifies new forms of planning; forms which could foster the transition to sustainability. Because the stakes are high - nothing less than the type of society we choose to promote in the long term - planning should be designed as a political process rather than just a technical or economic program. An important question is Can sustainability planning be considered as an emerging norm at the international level? The second section, Towards a New Social Contract, addresses the point that present generations are held accountable by future generations, and discusses strategies for designing and adopting a pathway to sustainability. A chapter entitled Insights for a Better Future in an Unfair World addresses the challenges of combining sustainability policies with social justice. The third section, Some Governance Issues, addresses global energy governance, multi-stakeholdergovernance for sustainable mobility, and territorial governance.
