Our global responses to the recession and climate change are inextricably linked. Political and policy decisions in the next ten months on the recession and on climate change will define whether our planet and its people are heading for a brighter future of prosperity and climate security, or a future of inequality, poverty, conflict, and destructive climate change. If governments round the world respond appropriately, the twin economic and climate crises could prove a profound and catalysing turning point in moving to a more just, equal and sustainable world. A just and global green new deal could be both an economic and a political turning point that will mark the start of a new era.
