Greensburg's Sustainable Comprehensive Master Plan was created in an effort to rebuild Greensburg after a devastating earthquake in 2007. The Master Plan provides a framework for the rebuilding of Greensburg based around the principles of environmental, economic, and social sustainability. As part of the plan, all municipal buildings must be constructed to LEED platinum standards and exceed the energy efficiency baseline code by 42%. The city also has a windfarm that produces 100% renewable energy for the town. It is voluntary for residential homes to comply with the ICC-700 National Green Building Standard. The Master Plan incorporates all aspects of green building- from site selection to walkability to landscaping to hazard mitigation- every element is covered.
