| 1 Emissions from combustion of waste materials derived from petroleum and emissions from some types of geothermal power plants. 2 Electricity-related CO2 emissions are based on electric power sector electricity sales to the other sectors and the emissions associated with the generation of that electricity. The electric power total emissions of 1,551 million metric tons is not included in the source total emissions for all sectors (of 4,872 million metric tons) to avoid double counting.
