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.

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.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

In this paper, we focus on the implications of growing shale gas production for the climate. If natural gas is abundant and less expensive, it will encourage greater natural gas consumption and less consumption of fuels such as coal, renewables and nuclear power. —Newell and Raimi.

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.
