In June 2004 Zion hosted a Climate Friendly Park workshop involving the Environmental Protection Agency and National Park Service. Following the workshop, a greenhouse gas emissions inventory was conducted and an action report prepared which you can see below. Since this initiative, Zion has implemented many of the action items resulting in a significant reduction in greenhouse emissions and cost savings. The work continues.
