Abstract:
The objective of the research aims to develop a theoretical study with different positions on the terms sustainable development and sustainability. Although fairly debated and accepted by common sense, the concept of sustainability does not have precision and ends up acquiring various senses, sometimes contradictory. The distinct ideological perceptions of environmental issues translate into different discourses. Each social sector presents its position on the “environmental crisis”, some catastrophic other weighted, some guiding solutions inside the current economic and social system and others suggesting drastic changes. In this context, and especially in the last three decades, the ideas of sustainable development (SD) and urban sustainability began to be discussed more intensively seeking possible solutions to urban and environmental problems.
