Normative justifications for sustainability: Approaches based on theories of justice
In the context of approaches that justify sustainability through concepts of intra- and intergenerational justice, the argument that a future generation should be at least as well off as the current one is relevant. In this sense, sustainable economic activity is required. What is meant by "doing just as well" is disputed within the theoretical strand. Technological, cultural, political and nature-related aspects of sustainability are discussed, among others.
