The case studies demonstrate the implementation of some of the actions and programs included in the database. They are not intended to provide step-by-step guidance on how to implement an action or program, but to describe a community’s experience with the action or program. They include information on the community’s size, what prompted the decision to pursue the action or program, and the outcomes.
 
The case studies are written for use by staff and officials from local jurisdictions, to help learn about GHG reduction actions and programs which can be implemented at the local level. They can be used alone or in conjunction with the database. Also be sure to visit the Links and Resources page for additional support materials.
