Stop the Coal Giveaways!

At a time when pollution from burning coal is wrecking our climate and making our air and water unsafe, an outdated federal coal-leasing program still allows big coal companies to shortchange American taxpayers for mining on public land. The American people deserve a fair price for the minerals on your land, and you deserve to know that your government isn't giving away dirty, dangerous coal to a huge and polluting industry. The BLM's system for mining on public lands needs to be reformed. 

Tell BLM: It's time for Big Coal to pay its fair share.

Wyoming Wildlife - Protect and Enjoy

SC Wyoming Chapter Working to Protect Public Lands

Welcome to Sierra Club Wyoming Chapter

The Sierra Club is America’s largest, oldest and most influential grassroots environmental organization.  Our mission is to explore, enjoy and protect the planet.

Wyoming is the home of some of the best national parks, intact ecosystems and wildlife populations in the world.  Wyoming is also rich in energy and mineral resources and has an economy presently dependent on the coal, gas and oil industries.   Sierra Club Wyoming Chapter works to protect our phenomenal natural environment from industrial development while promoting the transition in Wyoming to clean energy and a sustainable economy.

We urge you to become a member or renew your membership today.  We also invite you to get involved.  Be sure to check out our calendar below to participate in our hikes, films, meetings, and community events.  We welcome your donations to support our important work.

Thank you for all you do to protect Wyoming’s environment.

Our website proudly features images of Wyoming’s public lands, as captured by local and regional photographers.  We appreciate their generosity in donating the use of their photos.  The website header photo was contributed by Wayne Karberg.  Place cursor over other photos to see photographer credits.  If you would like to submit your photos for consideration, please contact us.
