Click
here to access my latest article in The Conversation, How green is your city: towards an urban sustainability index, that
discusses metrics used to assess the ecological, carbon and water footprint of
cities. As we transition into a more urban future, measuring, assessing and
evaluating urban environmental impact of cities is of major importance. We are
only just beginning the difficult task. We
need to refine these metrics, develop new ones and so create a standardized and
easily understood index of city sustainability. With better data and a standard
index, policies can be evaluated, targets set and institutions held to account.
A robust city sustainability index would benchmark
where we are now and provide a measure of progress in the future.
