Minnesota GreenStep Cities is a voluntary challenge, assistance and recognition program to help cities achieve their sustainability goals through implementation of 28 best practices. Each best practice can be implemented by completing one or more specific actions from a list of four to eight actions. These actions are tailored to all Minnesota cities, focus on cost savings and energy use reduction, and encourage innovation. The program is administered by the Minnesota Pollution Control Agency (MPCA) and CERTs is one of the project partners. Luke Welle, an undergraduate student from Bemidji State University and Tashi Wougdi Gurung, an Environmental Science undergraduate student on the Crookston Campus, will identify challenges to implementing GreenStep cities and how to overcome them. These results will be used to celebrate completed sustainability best practices by cities, identify implementation barriers for additional best practices and improve the CERTs program to cities in the Northwest Region.
