Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

EIA: US energy-related CO2 emissions in 2012 lowest since 1994; reflects drop in coal use

Green Car Congress

The largest drop in emissions in 2012 came from coal, which is used almost exclusively for electricity generation. During 2012, particularly in the spring and early summer, low natural gas prices led to competition between natural gas- and coal-fired electric power generators.

EPA report shows progress in reducing urban air toxics across US; 50% reduction from mobile sources since 1990

Green Car Congress

The US Environmental Protection Agency (EPA) released the Second Integrated Urban Air Toxics Report to Congress—the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics (also referred to as hazardous air pollutants or HAPs).

EPA proposes CO2 limits for future power plants; flexibilities for phasing in control technology; anticipates negligible impacts

Green Car Congress

The US Environmental Protection Agency (EPA) has proposed the first Clean Air Act standard for CO 2 greenhouse gas (GHG) emissions from new power plants. EPA is proposing that new fossil?fuel?fired Coal with carbon capture and storage (CCS): 200 lbs CO 2 /MWh. A company could build a coal?fired kg CO 2 /MWh. on controls.

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

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 Tg or million metric tons CO 2 equivalent.) Field production.

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

The US Environmental Protection Agency (EPA) released the already widely-discussed (albeit without much detail) “Clean Power Plan” proposal, which mandates a national average 30% cut in greenhouse gas emissions from existing power plants from 2005 levels by 2030. EPA is only proposing goals for states with fossil fuel-fired power plants.

Electric vs. Gasoline Cars: Uncovering the Real Climate Savior

The Truth About Cars

For instance, electricity generated from coal or natural gas is associated with higher carbon emissions, while renewable sources like wind or solar energy contribute negligible carbon pollution. The EPA's Power Profiler is an interactive tool that provides information about the electricity production mix in different regions.
