Case Study
SANGEATM Emissions Monitoring Software

In 2002, ChevronTexaco implemented a new software program it had developed to help it more easily and accurately estimate and manage energy use and greenhouse gas emissions at its facilities worldwide. We developed this program over several years to help our businesses estimate their emissions based on standard methods compiled by the American Petroleum Institute. Our goal was to provide an easy-to-use tool for estimating emissions based on the latest methodologies available. In an effort to take a leadership role in promoting industry standardization of comparable, consistent greenhouse gas emissions data, we have released the software free of charge to the worldwide energy industry.

The software, called SANGEATM Energy and Emissions Estimating System, is an automated, electronic data management information system for gathering greenhouse gas emissions and energy usage data from energy company operations. ChevronTexaco used the software in 2002 to compile the first, comprehensive greenhouse gas inventory for the newly merged company.

By combining greenhouse gas emissions and energy utilization estimates, the SANGEATM software is highly efficient-eliminating duplicate work and providing for consistent energy use reporting at a facility. The SANGEATM software is implemented as an enterprise-wide, complete process for data generation, calculation, analysis, reporting and management of data from exploration and production, refining and marketing, petrochemicals, transportation, electricity generation, manufacturing, real estate and coal activities.

In the six months since we announced that our software is available free of charge, more than 150 companies have contacted us to learn more about it. ChevronTexaco has delivered more than 80 copies of the software. For more information about SANGEATM , please contact:
