Reductions in carbon dioxide emissions result from our reduced energy consumption. Taking into account our production rate increases, we have reduced our CO2 emissions on a revenue-adjusted basis by 24.4 percent since 2002. And we will continue to reduce emissions to support our goal of reducing greenhouse gas emissions intensity by 25 percent in the next five years so that we more than offset the projected increases in our production rates with environmental improvements.
In this report, Boeing uses measurements of carbon dioxide emissions and energy use from major U.S. facilities. This method allows us the most consistent and accurate way to measure targets and performance improvements. The energy consumption at those facilities in 2007 resulted in 1.3 million tons of CO2.
Boeing may later in 2008 disclose an estimate of more comprehensive carbon dioxide emissions and energy use figures under the scope of the Carbon Disclosure Project (CDP6).
