U.S. GHG Emissions Flow Chart

The U.S. GHG Emissions Flow Chart provides a detailed breakdown of 2003 emissions totaling 6,978 MtCO2 equivalent. The largest contributing sectors are Electricity & Heat (32.4%) and Transportation (27.2%), with Carbon Dioxide (CO2) accounting for 85% of the total gas composition.

• In 2003, total U.S. emissions were 6,978 MtCO2 equivalent, with the primary contributing sectors being Electricity & Heat at 32.4%, Transportation at 27.2%, Energy (Industry) at 12.4%, Agriculture at 6.2%, Industrial Processes at 4.5%, and Waste at 2.6%.
• The composition of greenhouse gases is dominated by Carbon Dioxide (CO2) at 85%, followed by Methane (CH4) at 8%, Nitrous Oxide (N2O) at 5%, and HFCs, PFCs, SF6 at 2%.
