Introduction: Joining Forces to Accelerate Action

Abstract

Swift and comprehensive action is necessary for addressing the global challenge of achieving sustainability. The previous part has set out a series of opportunities and challenges to optimize urban sectors and the urban economy by greening them. However any fundamental change in pathway, be it through the transformation of a mature urban economic system and urban infrastructure or the steering of rapid urban growth, requires the involvement and active engagement of a range of stakeholders. Such a spectrum encompasses public, private and civic actors, groups and institutions; each has a range of roles to play, but most importantly each has the ability to maximize their potential through collaboration, cooperation and coordination.
