As the sole regional designee of the Department of Energy’s Clean Cities program, Yellowstone-Teton Clean Cities (YTCC) functions as Department of Energy’s on-the-ground advocate focused on petroleum displacement activities in the Greater Yellowstone Region. Currently consisting of nearly 90 organizations across the country, the Clean Cities program has been responsible for displacing over 2.5 billion gallons of petroleum fuel since its inception. Affiliation with the Clean Cities Program provides YTCC with access to regional and national support networks in order to bring a much broader perspective to local transportation projects. It also allows for access to unique funding opportunities related to supporting the Clean Cities mission. This affiliation, along with YTCC’s regional standing as a resource and advocate for sustainable and efficient transportation, creates an ideal scenario for YTCC to function as a clean transportation leader within the Greater Yellowstone Community in order to lessen the detrimental impacts of local transportation.
