US Cut CO2 Pollution by 3.8 Percent in 2012, Say Fed Energy Chiefs
From Al Jazeera
The United States cut energy-related carbon dioxide pollution by 3.8 percent last year, the second biggest drop since 1990, according to the Department of Energy’s Energy Information Administration (EIA).
The only recent year with a bigger percentage drop was in 2009, and reflected, in part, the impact of the financial crisis on industrial output and lower overall energy use.
But this year’s drop comes amid rising domestic GDP, suggesting that environmental and cultural trends rather than economic factors alone could be behind the cut in emissions.
The EIA said American cars and factories spewed 5.83 billion tons of carbon dioxide into the atmosphere in 2012, down from 6.06 billion in 2011, representing the lowest level for U.S. emissions since 1994.
Energy Department economist Perry Lindstrom said carbon pollution reduction is due to warm winter weather, more efficient cars because of new mileage requirements and an ongoing shift from coal-power to natural gas to produce electricity.
