The debate about sustainability can be traced back into the eighteenth century. It was revived following the publication of the Brundtland Report “Our Common Future” (1987) and the United Nations Conference on Environment and Development in Rio de Janeiro (1992). Since then, interest has been focused on developing new concepts between the seemingly opposing paradigms of strong and weak sustainable development as well as on their application in practice. Moreover, sustainable development entails normative implications that affect inter- and intragenerational justice.
