According to the U.S. Energy Information Administration (EIA), energy-related carbon dioxide (CO2) emissions decreased by 146 million metric tons (MMmt), from 5,405 MMmt in 2014 to 5,259 MMmt in 2015. This decline occurred despite growth in real gross domestic product (GDP) of 2.6% as other factors more than offset the growth in GDP. Energy-related CO2 emissions in 2015 were about 12% below 2005 levels. Emissions have declined in 6 out of the past 10 years. For additional details see the report.
