A new report released today shows that the EPA's proposed replacement rule could lead to  a rebound in power plant emissions of CO2 and co-pollutants that can degrade air quality and harm human health. The new report, titled "Carbon Standards Examined", is the result of four years of work by researchers with Science Policy Exchange, Resources for the Future, Syracuse University, Harvard T.H. Chan School of Public Health, and Boston University School of Public Health. The authors compared two hypothetical scenarios for "inside the fence line" and "beyond the fence line" power plant carbon standards compare to a no policy alternative.
