Energy Conservation Program: Energy Conservation Standards for Automatic Ice Makers

Our comment primarily concerns the Department of Energy’s (DOE) use of the social cost of carbon (SCC) in the cost/benefit analysis of the Energy Conservation Program: Energy Conservation Standards for Automatic Commercial Ice Makers proposed rulemaking. The determination of the SCC is so discordant with the best scientific literature on the equilibrium climate sensitivity and the fertilization effect of carbon dioxide — two critically important parameters for establishing the net externality of carbon dioxide emissions, at odds with existing Office of Management and Budget (OMB) guidelines for preparing regulatory analyses, and founded upon the output of Integrated Assessment Models (IAMs) which encapsulate such large uncertainties as to provide no reliable guidance as to the sign, much less the magnitude of the social cost of carbon. Additionally, as run by the Interagency Working Group (IWG), the IAMs produce illogical results that indicate a misleading disconnect between a climate change and the SCC value. And we show that the sea level rise projections (and thus SCC) of at least one of the IAMs (DICE 2010) cannot be supported by the mainstream climate science.

Until this situation can be properly rectified, the SCC should be barred from use in this and all other federal rulemaking. It is better not to include any value for the SCC in cost/benefit analyses such as these, than to include a value which is knowingly improper, inaccurate and misleading.
