Keystone Foe Steyer Brings Fight to Site of Obama Pledge

As the U.S. prepares to release an environmental review of the proposed Keystone XL pipeline, opponents are arguing that the project can’t meet a standard for carbon emissions that President Barack Obama set in June.

The opponents made their case yesterday during a conference at Georgetown University in Washington, where earlier this year Obama declared he wouldn’t back the project if it were found to significantly increase carbon-dioxide emissions, which many scientists have linked to global warming. The event was sponsored by NextGen Climate Action, a group funded by billionaire investor and pipeline foe Tom Steyer.
