Strongly different approaches to sustainability appear side by side in economics. The differences, the study argues, are not worth examining in terms of strong and weak dimensions of sustainability, as often occurs in professional debate. The distinction has much more to do with two clear schools of thought on the relation between nature and the economy - neo-classical environmental economics resting on welfare foundations, and ecological economics - though the dividing line is not always a sharp one. It is concluded that ecological economics makes cogent criticisms of the sustainability-related views and methods of environmental economics, often offering methodologically clear solutions as an alternative to these.
