Milwaukee's Vision for Community SustainabilityReFresh Milwaukee

On July 16, 2013, Mayor Barrett launched Milwaukee's first Sustainability Plan. The ReFresh Milwaukee Plan is a citywide strategic plan to develop a sustainable future for the community. ReFresh Milwaukee provides the vision for community sustainability over the next 10 years and seeks to make Milwaukee a center for sustainability innovation and thought leadership.

This plan sets goals and targets for individuals and organizations to achieve and provides a citywide roadmap for improving the environmental, economic and social conditions of Milwaukee's neighborhoods. ReFresh Milwaukee is a call to action to the community and connects residents, businesses and other groups working on sustainability issues.

The Global Compact Cities ProgrammeThe City of Milwaukee is proud to participate in the Global Compact Cities Programme (or Cities Programme), an urban component of the United Nations Global Compact; the world’s largest corporate responsibility initiative.
