| Data source: Monthly Energy Review, April 2024; preliminary data Note: Sum of data in columns and rows may not equal the totals because of independent rounding. 1 Energy-related CO2 emissions are emissions resulting from use of energy. 2 Other includes emissions from combustion of waste materials derived from petroleum and emissions from some types of geothermal power plants. 3 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 sector emissions are not included in the source total emissions for all sectors to avoid double counting. | ||||||
