This book argues that ethical reasoning should be adopted into policy processes in order to improve environmental regulations. It considers how public administrators and civil servants play key roles in policy making and implementation, and demonstrates how the inclusion of green public ethics at every stage of the policy process could drastically enhance sustainable development initiatives. Filling an important void in the literature on policymaking and environmental ethics, the book draws from empirical case studies to demonstrate how 'green' ethical reasoning can be utilised by practitioners and stakeholders in democratic governments. It will appeal to all those interested in public policy, public administration, philosophy and environmental studies.
