Who We Are

Advancing Clean and Efficient Transportation in Central Texas.

Mission Statement

To enhance the nation’s energy security, support economic prosperity, and improve air quality by fostering locally driven transportation energy choices that leverage domestic energy resources and innovative mobility technologies through collaborative partnerships with public and private stakeholders.

Our History

In 1994, Austin Clean Cities was the 6th coalition to join the U.S. Department of Energy’s Clean Cities Program, the first in Texas and the first to join from an area in attainment of the EPA’s standards for air quality. In 2000, Austin Clean Cities became Central Texas Clean Cities, having expanded to cover Bastrop, Caldwell, Hays, Travis, and Williamson counties. In 2012, the coalition reorganized into a DOE-recognized, membership-based, 501(c)(3) non-profit coalition known as Lone Star Clean Fuels Alliance. In 2017, after 16 years of serving as Executive Director, Stacy Neef retired and passed over leadership to our current director Elizabeth Munger. In 2024, Lone Star Clean Fuel Alliance became Central Texas Clean Cities.

Meet The Team

Our Team is committed to promoting clean transportation fuels and technologies including electricity, hydrogen, propane, natural gas, micro-mobility technologies, and vehicle miles traveled reductions. We collaborate with our stakeholders, sister Clean Cities Coalitions, Board of Directors, industry partners, and community organizations sharing our mission.

Elizabeth has been the Director since 2017. She began her career in alternative fuels in 1995 as the first Coordinator of the Laredo Clean Cities Coalition. She worked for Gladstein & Associates (now a TRS firm) on a variety of DOE funded projects including a Texas Clean Corridor project and International trade missions. She started The Green Group in 2001 and worked as a consultant for American Honda selling natural gas vehicles, marketing electric and hydrogen vehicles. She has also consulted for utilities and industry organizations. Elizabeth holds a BS in business from Roger Williams College and an MBA from the University of Rhode Island.

A DOE Clean Cities and Communities Coalition

Clean Cities and Communities is a U.S. Department of Energy (DOE) partnership to advance clean transportation nationwide. More than 75 DOE-designated Clean Cities and Communities coalitions work locally in urban, suburban, and rural communities to strengthen the nation’s environment, energy security, and economic prosperity. As partners with DOE’s Vehicle Technologies Office, coalitions, like Central Texas Clean Cities, work to deploy affordable, efficient, and clean transportation fuels; energy-efficient mobility systems; and other fuel-saving technologies and practices. Since Clean Cities and Communities began in 1993, coalition activities have reduced greenhouse gas emissions by 72 million tons and helped put 1.6 million alternative fuel vehicles on the road. Together, coalitions create a compounding impact nationwide that advances U.S. energy resilience and reduces vehicle emissions while supporting regional economic development and job growth.
