New in paperback. Hardcover was published in 2022. In recent years, the Green New Deal has moved from relative obscurity to front and centre of policy discussions and public debates about how to respond to the climate crisis. It has been credited with radically changing the nature of the conversation on climate change and with re-energizing the environmental movement at a critical time. All Green New Deal proposals share an emphasis on the need for governments (rather than markets) to lead the energy transition. However, they differ in other respects. This Handbook analyses the fundamentals underlying all Green New Deals as well as exploring national and regional variations.
