ICLEI's Five Milestones provide a simple, standardized means of assessing sustainability challenges, establishing goals, developing and implementing a plan, and monitoring, measuring and reporting performance.

The methodology underlying the Five Milestones for Sustainability is based on the Five Milestones for Climate Mitigation and involves a more broad process for addressing both climate and sustainability.

Local governments that wish to develop a plan that not only addresses greenhouse gas emissions reductions, but also includes related measures to improve local sustainability, should follow the Five Milestones for Sustainability. The Five Milestones for Sustainability also complement the STAR Community Index, which is currently in development. Local governments will be able to follow the Milestones while also receiving credits through the STAR rating system.
