AB: Using data from the Department of Energy's Energy Information Administration (EIA), a technique is developed to estimate the monthly consumption of solid, liquid and gaseous fossil fuels for each state in the union. This technique employs monthly sales data to estimate the relative monthly proportions of the total annual carbon dioxide emissions from fossil-fuel use for all states in the union. The University of North Dakota (UND) results are compared to those published by Carbon Dioxide Information Analysis Center (CDIAC) at the Oak Ridge National Laboratory (ORNL). Recently, annual emissions per U.S. state (Blasing, Broniak, Marland, 2004a) as well as monthly CO2 emissions for the United States (Blasing, Broniak, Marland, 2004b) have been added to the CDIAC website. To determine the success of this technique, the individual state results are compared to the annual state totals calculated by CDIAC. In addition, the monthly country totals are compared with those produced by CDIAC. In general, the UND technique produces estimates that are consistent with those available on the CDIAC Trends website. Comparing the results from these two methods permits an improved understanding of the strengths and shortcomings of both estimation techniques. The primary advantages of the UND approach are its ease of implementation, the improved spatial and temporal resolution it can produce, and its universal applicability.
