Siena has a responsibility to live in a way that benefits not only our campus, but the greater community as a whole. Sustainability can be a broad topic, but is nicely summarized by the Brundtland Report (Our Common Future):
"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."
It contains within it two key concepts:
the concept of needs, in particular the essential needs of the world's poor, to which overriding priority should be given; and
the idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs."
