US electric power sector CO 2 emissions have declined 28% since 2005 because of slower electricity demand growth and changes in the mix of fuels used to generate electricity, according to the US Energy Information Administration (EIA). In the United States, most of the changes in energy-related CO 2 emissions have been in the power sector.

for year 2007. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. 2007); and predicted national data from the National Long-term Development Plan (NLDP) (2008?2050). 2007 were used in this study.

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Most of the two countries’ sulfur dioxide emissions come from coal-fired power plants and coal-burning factories.

With the exception of 2010, emissions have declined every year since 2007. The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation. The regulations would make 65% of coal plants nationwide as expensive as natural gas, even if gas prices rise significantly.

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 In 2011, CH4 emissions from coal mining were 63.2

Underground coal gasification uses paired wells in a coal seam: one an oxidant injection well, the other the syngas producer well. CIRI), an Alaska Native corporation, is proposing an underground coal gasification (UCG) project that would use the resulting syngas to fuel a new 100 MW combined cycle power plant.

Overall, US energy-related CO 2 emissions have fallen 15% from their peak of 6,003 MMmt in 2007. CO 2 emissions from coal fell by 14.6%, the largest annual percentage drop in any fuel’s CO 2 emissions in EIA’s annual CO 2 data series dating back to 1973. The United States now emits less CO 2 from coal than from motor gasoline.
