US energy-related CO 2 emissions in 2012 were the lowest since 1994, at 5.3 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. Duke study.

For the first eleven months of 2013, natural gas consumption in the electric power sector was below 2012 levels because of relatively higher natural gas prices compared with coal prices, and cooler summer weather compared with 2012, according to the US Energy Information Administration (EIA).

US greenhouse gas emissions by gas. The US Environmental Protection Agency (EPA) released its 19 th annual report of overall US greenhouse gas (GHG) emissions, showing a 3.4% decrease in 2012 from 2011. Total emissions of the six main greenhouse gases in 2012 were equivalent to 6,526 million metric tons of carbon dioxide.

Among the findings of the EIA analysis: CO 2 emissions form natural gas surpassed those from coal in 2016. Natural gas CO 2 emissions have increased every year since 2009. These emissions were highest in 2007, prior to the recession, and have not returned to those levels, despite increasing every year since 2012.

over the prior year, according to the EPA’s newly published Inventory of US Greenhouse Gas Emissions and Sinks: 1990–2013. By sector, power plants were the largest source of emissions, accounting for 31% of total US greenhouse gas pollution. From 2012 to 2013, CO 2 emissions from the transportation end-use sector increased by 1.0

For purposes of this rule, fossil fuel-fired EGUs include utility boilers, IGCC units and certain natural gas-fired stationary combustion turbine EGUs that generate electricity for sale and are larger than 25 megawatts (MW). The proposed rulemaking establishes separate standards for natural gas and coal plants. Background.

Specific circumstances, such as the very warm fourth quarter of 2015 and relatively low natural gas prices, put downward pressure on emissions as natural gas was substituted for coal in electricity generation. Coal’s share of total electricity generation in the power sector fell from 54% in 1990 to 34% in 2015.
