Since the promulgation of the 2030 Agenda for Sustainable Development, adopted by the member states of the United Nations in 2015, the concept of sustainability has become pervasive in society. Most social organizations, businesses, institutions, political forces, associations, movements recognize themselves around the idea that sustainability is a goal to be hit. Businesses and public bodies are directing their social and environmental balance sheets, their development programs and plans on the basis of the indications that come from the thematic objectives set by the United Nations. No development strategy could therefore disregard sustainability objectives. Paradoxically, the major limitation of the concept of sustainability lies precisely here.
