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.

Great Smoky Mountains National Park is working with East Tennessee Clean Fuels and the Land of Sky Clean Vehicles coalition to cut petroleum use. The park will add four propane pickup trucks and install two propane refueling stations. The park is also replacing three gasoline pickup trucks with all-electric vehicles, converting five gasoline mowers to operate on propane, and installing four publicly accessible electric vehicle charging stations. These activities are estimated to help the park reduce its annual greenhouse gas emissions by almost 40 million tons of CO2 and displace the use of nearly 8,900 gasoline-gallon equivalents of petroleum per year.
