EIA: “Energy-related carbon dioxide emissions vary significantly across States, whether considered on an absolute or per capita basis. The overall size of a State, of course, determines much of the absolute level of a State’s emissions. Available fuels, types of businesses, climate, and population density also play a role in overall and per capita emissions. It should be noted that 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.”
