Measuring Our Progress

Carbon Dioxide Emissions

Boeing's CO₂ emissions primarily result from energy consumption. By focusing on conservation and efficiency improvements, we reduced absolute CO₂ emissions by 3 percent in 2010 compared with the previous year. Boeing has reduced CO₂ emissions by 28 percent on a revenue-adjusted basis since 2002.

CO2 Emissions at U.S. Sites – Absolute	CO2 Emissions at U.S. Sites – Revenue Adjusted
Includes data from, core metric sites, Bellevue, Wash.; Corporate Headquarters, Chicago, Ill.; Boeing Commercial Airplanes operations in Long Beach, Calif.; Seal Beach, Calif.; and West Hills, Calif. 1 metric ton = approximately 1.1 U.S. ton (or approximately 2,200 pounds). CO2 emissions are calculated based on consumption of electricity, natural gas and fuel oil. (Our facility in Philadelphia is the only major U.S. site that uses fuel oil for heating.) Consumption of other fuels is not represented. Emissions from purchased electricity is calculated using regional eGRID 2007 electricity CO2 factors. Emissions from natural gas and fuel oil are calculated using the emission factors provided in the U.S. EPA greenhouse gas mandatory reporting rule. 2008 data reflects reduced production as a result of a labor strike. Data in the chart is normalized for divestitures by excluding Boeing Commercial Airplanes operations in Wichita (now Spirit AeroSystem) from 2002 to 2005. Boeing Defense, Space & Security's Wichita operations are included in this data.
