This book emerges from a three-year Australian Research Council-funded study that asks how the formation and (d)evolution of leadership has impacted on public environmental debate. To do this, it draws on extensive news text analysis and public opinion survey data, as well as qualitative interviews with Australian and international movement actors. The volume investigates environmental leadership in a period of rapid political and media change by examining the nature, variety and scope; specifically, how it is understood and generated and how it changes over time. For the first time, the interconnected roles of leaders and media in constructing environmental issues are researched together, providing new evidence-based understandings of the people and processes driving public debate on environmental futures.
