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.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

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.)

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.

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.
