In the 21st century, cities will increasingly be the frame through which we
understand and shape our shared economic, political and cultural circumstances.
They will also be ground zero for the collision of economic, environmental and
social imperatives that define sustainability. Together, these facts suggest that in
proactively addressing the challenge of urban sustainability, business and others
may have an opportunity to harness the power and positive characteristics of cities
to drive sustainability more widely.
It is in this context that Citystates proposes a pair of related hypotheses: (1)
sustainability needs cities as much as cities need sustainability, and (2) business
and others should view cities as an increasingly crucial and constructive frame
through which to understand and pursue sustainability. Specifically, we see cities
as both linchpins and levers for sustainable development, and a source of potential
lessons for how to drive the sustainability agenda forward.
