Document summary
In June 2012, a panel from the US Court of Appeals for the District of Columbia Circuit unanimously upheld the US Environmental Protection Agency’s (EPA) landmark greenhouse gas (GHG) regulations, keeping intact the EPA’s authority to regulate carbon emissions from vehicle tailpipes and stationary sources. This report emphasizes the importance of the case as it effectively clears the way for the EPA to proceed with its proposed rules to regulate CO2 emissions from both new power plants and from other new stationary sources, in addition to pressing ahead with new vehicle emission standards. In addition, it looks at implications for investors in energy markets.
