This book examines the impact of current and emerging digital technologies on global environmental governance, and in particular on environmental civil society organizations. Technological innovations are constantly emerging: internet and social media platforms, blockchains, big data, and artificial intelligence are some of the most common or promising digital technologies of our times. Through case studies and the analysis of concrete applications of digital technologies, this book shows how these digital technologies can be deployed to support global environmental governance, and in particular a multi-stakeholder approach to the protection of the environment. It provides an overview of the diverse uses of these digital technologies by civil society organizations (CSOs) in global environmental governance. In this fast-changing context, the capacity of environmental CSOs to manage and benefit from digital technologies, and to produce and distribute information, can strengthen their participation in global environmental governance. Their key roles, including advocacy, monitoring, knowledge production, fundraising, nudging individual behaviors, and project implementation, greatly benefit from the use of these technologies. By examining some of the most-utilized current digital technologies and presenting some of the most prominent emerging ones, this book aims to illustrate how active civil society organizations operate, and how ICTs support some of their roles, and therefore their participation in global environmental governance. This book will appeal to scholars and students of environmental studies and politics, global governance, political sociology, geography and communication studies along with policy makers and communication specialists from the environmental community.
