Carbon dioxide emissions rose by more than 11 percent in Montana last decade as the state continued to have one of the highest per capita greenhouse gas emission rates in the country.
The Energy Information Administration says in a new report that energy-related carbon dioxide emissions in Montana totaled 34.9 million tons in 2010. That translates into more than 35 tons per resident.
Total U.S. carbon dioxide emissions fell 4 percent during the same period.
Only five states had high per capita emission rates — Wyoming, North Dakota, Alaska, West Virginia and Louisiana.
Montana is a net exporter of energy, meaning most of its electricity production is consumed by residents in other states.
Carbon dioxide is considered by scientists to be a major contributor to climate change.
