The focus of Norton's book is the distinction between objectives and values in developing environmental policies. Norton argues that environmentalism is a coalition of many groups working toward common objectives, but unlike other social action movements the environmental coalition does not have shared moral principles.

Very few moral philosophers have written on climate change.1 This is puzzling, for several reasons. First, many politicians and policy makers claim that climate change is not only the most serious environmental problem currently facing the world, but also one of the most important international problems per se.2 Second, many of those working in other disciplines describe climate change as fundamentally an ethical issue.3.
