Cool Cities Campaign

Cool Cities Co-Chairs: Lee Berryman-Tedman, 214-726-6328; Clark Shaffer


The Dallas Sierra Club is getting more cities on board the Cool Cities train! We’re asking mayors of all cities all over North Texas to sign the U.S. Mayors Climate Protection Agreement and make a commitment to address global warming by making their cities more energy-efficient. There’s a lot you can do to help!


Join a Lobbying Team


Help us convince your city’s mayor to get on board. Teams are working now on the following cities and can use your help. Don’t see your own North Texas city? Contact Lee to talk about starting a team where you live.

Cities that have signed: Addison, Allen, Celina, Farmers Branch, Flower Mound, Forney, Garland, Grand Prairie, Grapevine, Irving, Lewisville, Mesquite, Prosper, Rockwall, and Wylie.

Join or Support Our Speaking Team 


There are 2 ways to help our speaking team:

  • Be a public speaker. Take our message of energy efficiency to adult Sunday School classes, homeowner’s associations, PTAs and business groups.
  • Support our speaking team. Help us get speaking appointments.

We’ll provide all the training and resources you need. Do something good for the environment, your community and yourself – join our Cool Cities team!
