Tammie Bostick

Executive Director & Utah Clean Cities State Lead

Tammie Bostick leads Utah Clean Cities Coalition (UCCC) as Executive Director with a passion for clean fuels, clean air, and clean strategies. Tammie joined Utah Clean Cities in 2015 and considers now is the most exciting time to work in transportation in history – thinking globally and acting locally, in a world where everyone is an ally. 

She was appointed in 2017, to the Utah Governor’s Motor Vehicle Review Board consulting with state fleet operations. Since 2019, Tammie has also served as the Vice President of Transportation Energy Partners, TEP, a collaborative board with the Clean Cities Coalition Network that advocated for advanced transportation focused federal policy and Clean Cities advocacy. Beginning in 2021, she was honored to begin serving on the Utah State University ASPIRE Societal Impact committee focusing on near port communities and underfunded transportation areas.

Beginning in 2020, Utah Clean Cities became the primary investigator of two highly innovative projects with the Department of Energy Vehicle Technologies Program: EVZion and CORWest. EVZion is piloting and demonstrating the feasibility of zero-emission electric shuttles in the East Zion National Park area. The CORWest project connects eight Western regional states developing electric corridors in rural, gateway communities across the intermountain region. 

Additional projects that Utah Clean Cities mobilized under Tammie’s leadership include an innovative recognition program for workplace charging, Work Electric which is housed in Drive Electric Utah .This program pairs with the Beyond Zero Green Fleets Program which guides fleets to climate positive targets to clean energy infrastructure and zero emission transportation management plans targeting zero emissions and climate resiliency.

Tammie addresses private and public leadership locally and nationally on the future of transportation and climate communication focusing on actionable steps for fleets that include advanced fuels, vehicles and visionary deployments of new technologies. She is actively engaged with local and national Renewable Natural Gas, RNG, and innovative hydrogen projects with the goal of demonstrating carbon-benefiting fleets and infrastructure modeling. 

Tammie is a Utah native and graduated from the University of Utah in Organizational Communication. Her life experiences have helped deepen her commitment to preserving the delicate balance of Utah’s beautiful landscape and abundant resources with advanced, state-side clean energy and fuels that are economically and ecologically sound, renewable, and ultimately sustainable. 

Tammie lives and works in Salt Lake City.  She enjoys the splendor of Utah’s natural spaces and practices mindful mobility with her electric car, e-bike and her favorite hiking shoes.

Clean Cities University Workforce Development Program

Argonne National Laboratory offers internships through the Clean Cities University Workforce Development Program, which unites Clean Cities coalitions across the country with students interested in changing the future of on-road transportation.

Internships with Clean Cities coalitions are available throughout the year for undergraduate (junior or senior) or graduate students in a variety of majors, including communications, public relations, business, marketing, engineering, environmental sciences, urban planning, and others.

Each year, students in the program work with Clean Cities coalitions to implement and increase awareness of alternative fuels, fuel-saving technologies and practices, and new mobility choices. Interns work with coordinators and stakeholders in the community to plan events, analyze data, research markets, design websites, and promote initiatives through social media and public relations.
