Environmental issues are now firmly on the global political agenda. Major UN summits and even meetings of the G8 most powerful economies in the world often feature environmental issues, especially climate change. We have now had nearly fifty years of international environmental diplomacy, such that unsurprisingly ‘the environment’ is part of everyday parlance in the practice and teaching of global politics. The same cannot be said for Green politics and perspectives on key global issues coming from more radical Green positions. Despite the potential contributions of Green thinking to an understanding and explanation of the underlying causes and potential solutions to the multiple crises engulfing global politics around war, poverty and social inequality or climate change, Green perspectives on global politics issues have rarely been articulated or brought together and have yet to gain traction. In a modest way, this book seeks to remedy that.
