"The ruling, which addresses four separate lawsuits, upholds the underpinnings of the Obama administration's push to regulate carbon dioxide emissions, and is a rebuke to a major push by heavy industries including electric utilities, coal miners and states like Texas to block the EPA's path."
Several Reuters reporters explained the regulatory ramificatons of the ruling and their historical underpinning. The basis for the four lawsuits was the 2009 'endangerment finding' by the EPA that stemmed from the landmark Massachusetts vs. Environmental Protection Agency in 2007 "that greenhouse gases are an air pollutant that can be regulated under the Clean Air Act."
"The ruling clears the way for the EPA to proceed with first-ever rules limiting carbon dioxide emissions from newly built power plants, and to move forward with new vehicle emission standards this summer.
Brent Kendall of the Wall Street Journal explains the likely effects on coal power plants.
"The standards, first proposed in March, are expected to make construction of new coal plants increasingly unlikely as power generators opt for natural gas.
Southern Co. and Duke Energy Corp. are building two "clean coal" power plants that will turn coal into a combustible gas to make electricity. But the cost of the plants-about $3 billion apiece-means that the technology is unlikely to be widely adopted."
Kendall writes that an appeal will most likely be unsuccessful. Undoubtedly coal supporters will turn to Congress in hopes of curtailing EPA's authority. An alternative path would be to have Congress adopt a "market-based climate bill", suggested by Paul Bledsoe, a senior adviser at the Bipartisan Policy Center.
