Abstract: Texaco's global greenhouse gas emissions inventory methodology

An emission inventory is a powerful, multi-purpose tool for regulators, public interest groups and other stakeholders in the environmental protection arena. Given growing conviction that market-based approaches are more effective than command-and-control regulations, inventories will increasingly be used to influence the behavior of companies in the market place. Carbon dioxide (CO2) and other greenhouse gas (GHG) emissions are becoming important elements in the emissions inventory. Nations have already been required to report estimates of their emissions under the Framework Convention for Climate Change. Under the Kyoto Protocol, the emissions inventory of the regulated community will come under additional scrutiny as emissions targets and timetables will have to be met once the Protocol is put in place. This paper describes methodology for the generation of a Texaco worldwide emissions inventory.

Data accuracy and consistency, and the cost and timing of delivery of data from Texaco worldwide business units were important considerations in the establishment of the emissions inventory methodology. Texaco's methodology is largely based upon the coupling of emission factors with fuel or product throughput or equipment component count. The Texaco emission source list is comprehensive across Texaco’s emissions sources worldwide and, in some cases, uses emission factors based upon more recent source measurements. This paper describes the basis for generation of a worldwide emissions inventory for the company.
