About the data. Figures are energy-related carbon dioxide emissions: CO₂ from burning coal, natural gas and petroleum, in million metric tons. Emissions from power plants are counted in the state where the electricity is generated, not where it is used. Other greenhouse gases and non-energy sources such as agriculture are not included.
