Leslie is joined by Timothy Cama, energy and environment staff writer at "The Hill."

They discussed Timothy's recent piece regarding President Obama's executive order that he will sign Thursday ordering federal government agencies to slash their greenhouse gas emissions.

Since the federal government is the largest single consumer of energy in the country, its actions can make a major dent in the greenhouse gas emissions of the country as a whole.

That means cuts in the government can send the country a long way toward Obama’s goal of reducing the United States’s greenhouse gases 26 percent to 28 percent below 2005 levels by 2030.
