Energy efficiencies achieved through Exxon Mobil Corporation’s Global Energy Management System (GEMS) have reduced annual greenhouse gas emissions by approximately 8 million metric tons, the equivalent of removing about 1.5 million cars from the roads.¹

Exxon Mobil Corporation continues to promote and develop cogeneration projects. Cogeneration, the simultaneous production of electricity and useful thermal heat/steam in a single process, significantly reduces energy consumption and improves efficiency. At our Baytown Olefins Plant, for example, a 160-megawatt gas-turbine generator, coupled with a heat-recovery unit that can produce 560,000 pounds-per-hour of steam for use in manufacturing processes, has an efficiency rate of about twice that of traditional power generation.

Overall, more than $1 billion has been invested in cogeneration projects at over 30 locations worldwide. These projects have reduced global carbon dioxide (CO2) emissions by more than 10.5 million metric tons annually. That’s the equivalent of removing an additional 2 million cars from the roads.

Globally, we strive to minimize the flaring of natural gas. That includes investing more than $3 billion worldwide in gas utilization and commercialization projects to eliminate routine gas flaring. ExxonMobil refineries and petrochemical plants were successful in reducing flaring by more than 10 percent in 2006. At our Baytown complex in Texas, we have reduced flaring by 80 percent since 2003.

ExxonMobil's building in Fairfax, Virginia, was recently awarded Energy Star recognition by the U.S. Environmental Protection Agency (EPA) for its energy efficiency efforts. In November 2007, the Baton Rouge Refinery was awarded Energy Star status.  The Energy Star Award is the national mark of excellence in energy performance.
