The Keystone pipeline encourages the development for many decades of Alberta's tar sands, some of the dirtiest fuel on the planet.

The United States can, and must, refuse to be complicit--refuse to be a partner--in harvesting this filthy fuel.

Keystone is about yesterday’s power. We must focus--as engineers, economists, and parents and consumers--on tomorrow's power. Our goal is to power our country with energy that is clean, affordable, and sustainable.

We must defeat this pipeline. Sign the petition to send a message to President Obama to stop the Keystone pipeline.
