U.S. Energy Information Administration Report Released: State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010

Recently, the U.S. Energy Information Administration (EIA) released a report titled, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010 (2013). According to the overview for the 21-page report available here,
[e]nergy-related carbon dioxide emissions vary significantly across states (Figure 1), whether considered on an absolute or per capita basis. The overall size of a state, as well as the available fuels, types of businesses, climate, and population density, play a role in both total and per capita emissions. Additionally, each state’s energy system reflects circumstances specific to that state. For example, some states are located near abundant hydroelectric supplies, while others contain abundant coal resources.This paper presents a basic analysis of the factors that contribute to a state's carbon dioxide profile. This analysis neither attempts to assess the effect of state policies on absolute emissions levels or on changes over time, nor does it intend to imply that certain policies would be appropriate for a particular state.
. . .
The term "energy-related carbon dioxide emissions" as used in this paper, includes emissions released at the location where fossil fuels are used. For feedstock application, carbon stored in products such as plastics are not included in reported emissions for the states where they are produced.

It is also important to recognize that the state-level carbon dioxide emissions data presented in this paper count emissions based on the location where the energy is consumed as a fuel. To the extent that fuels are used in one state to generate electricity that is consumed in another state, emissions are attributed to the former rather than the latter. An analysis that attributed "responsibility" for emissions with consumption rather than production of electricity, which is beyond the scope of the present paper, would yield different results.
