The U.S. Environmental Protection Agency’s Clean Power Plan, proposed in June, would require existing power plants to reduce carbon dioxide (CO2) emissions 30 percent below 2005 levels by 2030. Although the national average would be 30 percent below 2005 levels by 2030, the specific reduction target for each state varies.
The CO2 reduction targets for each state are based on that state’s energy mix. Because each state has a unique energy mix, the various reduction techniques achieve different savings in each state and thus significantly different targets.
Under the proposed rule, the benchmark year would be 2012, which means any improvements completed at coal-fired power plants during that year or before would not be recognized.
EPA is expected to issue a final rule by June 2015. States would have until June 2016 to file their compliance plans, with one- and- two-year extensions available to qualifying states.
The following table shows the proposed state reduction targets (lbs/MWh) compared with historic emissions rates.
