Help protect 3 million acres of forest in Western Colorado

The Forest Service is accepting public comment on the management of Colorado’s Grand Mesa, Uncompahgre, and Gunnison National Forest (GMUG) until May 3rd. Add your voice to protect one of our treasured public lands!

Stop the Trump Administration's attack on our clean air

This proposal would severely weaken efforts to curb waste on public lands, leading to the loss of hundreds of millions of dollars of taxpayer-owned energy every year. This is a gut punch to Americans that will make our kids sick and hurt Western communities.

Protect the Clean Power Plan

EPA Administrator Scott Pruitt just announced his intention to repeal the Clean Power Plan, one of our nation’s most important climate change actions. The EPA is now accepting comments on their polluter-backed plan, but not for long.


Stand up against Trump's rollback of vehicle pollution standards

The Trump administration just announced its intention to roll back the 2012 Federal Vehicle Emissions Standards. Without them, the amount of pollution from passenger vehicles — already dangerously high — will get even worse. Urge Governor Hickenlooper to stand up to the Trump administration and fight back against these rollbacks!
