2002 ChevronTexaco Corporate Responsibility Report Environmental IssuesClimate Change (Continued)Performance: Conducting the FirstEmissions Inventory as a New CompanyIn 2002, we implemented our SANGEA Energy and EmissionsEstimating System to compile our first corporatewide greenhouse gasemissions inventory. For 2002, our total net emissions were approximately60 million metric tons of CO 22002 Greenhouse Gas Emissions*Millions of metric tons CO 2 equivalentequivalents for all businesses andoperations we have financial6050UpstreamDownstreamOther**interests in, based on its equityshare in those businesses andoperations. These emissions are34.44030roughly equal to the total greenhousegas emissions from thecountries of Austria or2023.5Singapore. Eighty-seven percent1002.3of our emissions are CO 2 and 13percent are methane, with traceamounts of nitrous oxide.*These numbers do not include Dynegy Inc.or Chevron Phillips Chemical Company LPemissions. ChevronTexaco’s net equity shareof Chevron Phillips’ emissions for 2002 isestimated to be 3.4 million metric tons ofCO 2 equivalents.**Other includes the greenhouse gas emissionsof ChevronTexaco’s shipping, power andgasification, and coal businesses as wellas administrative and corporate services.2002 Sources of Greenhouse Gas EmissionsMillions of metric tons CO 2 equivalentOther*18%Flaring& Venting26%Combustion56%We recognize that in additionto the greenhouse gas emissionsgenerated by our operations,the use of our products as fuelcontributes to worldwide greenhousegas emissions. Accordingto the Coalition for EnvironmentallyResponsible Economies(CERES), a U.S.-based environmentalorganization, our oiland gas production in 2002 wasthe source of 415.2 million tonsof end-use CO 2 emissions byour customers, equal to approximately1.7 percent of globalemissions from fossil fuels.Future Goals: Setting Emissions TargetsBeginning in 2003, ChevronTexaco will develop a consistent internalmetric for tracking greenhouse gas emissions on a per-unit-of-outputbasis and will make preliminary emission forecasts. We will establishemissions goals across our company in 2004. These goals will applyto our upstream, downstream and power and gasification operatingcompanies and, where possible, joint ventures and partially ownedsubsidiaries. Also beginning in 2003, we will initiate an independentthird-party review of our emissions management system, leading toan audited greenhouse gas emissions inventory that will ensure a strongfoundation for our emissions management program.*Other includes acid gas removal, coke combustion,crude oil transport, crude oil storage, flashing,fugitives, glycol dehydrators, indirect emissionsand sulfur recovery.© 2003 ChevronTexaco Corporation.
