Greenovation : urban leadership on climate change Cities on the front lines Energy efficiency : from buildings to districts and neighborhoods Beyond the building : district heating and cooling Renewable cities Electrifying transportation Liberating cities from cars Eco innovation districts accelerating urban climate action Cities and a green new deal The elements of greenovation. Collectively cities take up a relatively tiny amount of land on the earth yet emit 72 percent of greenhouse gas emissions. Clearly cities need to be at the center of any broad effort to reduce climate change. This book argues that too many cities are only implementing random acts of greenness that will do little to address the climate crisis. It instead calls for greenovation using the city as a test bed for adopting and perfecting green technologies for more energy efficient buildings transportation and infrastructure more broadly. Further the text contends that while many city mayors cite income inequality as a pressing problem few cities are connecting climate action and social justice another aspect of greenovation. Focusing on the biggest producers of greenhouse gases in cities buildings energy and transportation the book examines how greenovating cities are reducing emissions overall and lays out an agenda for fostering and implementing urban innovations that can help reverse the path toward irrevocable climate damage. Drawing on interviews with practitioners in more than twenty North American and European cities the book identifies the strategies and policies they are employing and how support from state provincial and national governments has supported or thwarted their efforts
