National Parks Initiative

Clean Cities partners with the National Park Service (NPS) through the Clean Cities National Parks Initiative to support transportation projects that educate park visitors on the benefits of cutting petroleum use and vehicle emissions. Since 2010, Clean Cities and NPS have partnered on 35 projects to deploy alternative fuel and fuel-efficient vehicles to the road, reduce vehicle idling, and improve vehicle efficiency. These actions support and coincide with NPS's efforts to address climate change impacts.

Mammoth Cave National Park started using E85 in 1999 and today runs all its vehicles on alternative fuels. Thanks to new funding, the park is adding four propane-powered school buses, two propane-powered pickup trucks, and one electric utility vehicle to its fleet. In addition, park personnel are partnering with the Kentucky Clean Cities Partnership to enhance efforts to educate visitors, employees, and the media about the benefits of using alternative fuels.
