As governments around the world grapple with the challenge of delivering environmental sustainability, attention has recently focused on the role that citizens should play in meeting the challenge. In advanced industrial countries such as ours, which operate in the political framework of liberal capitalism, what relevance can we place on 'environmental citizenship'?This book looks at the obstacles and opportunities which exist within this context and examines the possibility of ethical investment, the social economy and considers whether there is space in the capitalist economy for environmental citizens to 'do the right thing?'This book is a special issue of the leading journal Environmental Politics.
