EIA: U.S. Greenhouse Gas Emissions Increased by 1.4% in 2007
The total emission of greenhouse gases in the United States increased by 1.4% in 2007, according to DOE's Energy Information Administration (EIA). An EIA report released on December 3 found that U.S. greenhouse gas emissions reached the equivalent of 7.282 million metric tons of carbon dioxide in 2007, with the increase mainly attributed to greater weather extremes and a decrease in hydropower production. While carbon dioxide emissions increase by 1.3% in 2007, other greenhouse gases increased at a faster rate, including a 3.3% increase in emissions of the most powerful greenhouse gases, such as refrigerants. Since 1990, U.S. greenhouse gas emissions have risen by nearly 17%. See the EIA press release and the full report.
