Book excerpt: Some have argued that the rate and scale of human-induced global environmental change is so significant that it now constitutes a new geological epoch in the Earth’s history called the Anthropocene (Zalasiewicz et al, 2011; Steffen et al, 2011). More than ever, there is a need to have appropriate and effective environmental policies that address the challenges of climate change, biodiversity, food, water and energy insecurity, environmental pollution, poverty alleviation and environmental equity. The short guide to environmental policy provides a concise introduction to post-war environmental policies, bringing together perspectives from a range of fields including economics, sociology, politics and social policy. It covers a broad range of issues, including causes and effects of contemporary environmental issues, policy approaches to addressing environmental problems, challenges to implementing environmental policies and future environmental challenges. This book is an essential introduction to all those interested in how policies can address environmental problems.
