On June 2, the EPA released its much anticipated proposed rule mandating a reduction in carbon emissions from existing power plants.[1] The rule requires an overall national decrease in carbon emissions by 30% from existing plants by 2030. The proposed rule instructs states to submit plans to achieve state specific goals for emission reductions. Alternatively, states may collaborate with other states and submit a joint plan. Plans must be submitted by 2017, or 2018 if collaborating with other states.[2]
