Rocky Mountain National Park

Rocky Mountain National Park, with more than 3 million annual visitors, is the fifth most-visited park in the NPS system. With support from Northern Colorado Clean Cities in 2013, the park purchased one propane pickup truck and two Chevy Volts, installed two electric vehicle charging stations, and boosted idle-reduction through technology deployment and a comprehensive education and outreach program.
