U.S. Greenhouse Gas Emissions Lowest Since 1994

U.S. greenhouse gas emissions (GHGs) haven't been this low since 1994, when Ace of Base and Sheryl Crow were at the top of music charts. The fall of nearly 1 billion a year from its peak in 2007 is largely a result of a major displacement of coal-fired electrical generation with natural gas, which only emits half the GHGs that coal emits per unit of energy.
