spill prevention

ExxonMobil is committed to the prevention of spills from our operations. Our industry-leading spill performance is a result of ongoing upgrades, key equipment replacements, and comprehensive inspection and surveillance programs. The number of spills in 2007 was down by about 15 percent from 2006 and continued a trend that has resulted in an average 13-percent reduction per year since 2000. In 2007, our total volume spilled was about 8000 barrels, most of which was recovered at the site of the spill.

Despite achieving a record low in both the number and volume of spills in 2007, we continue to strive for further improvement. We conduct spill reduction awareness communications and workshops in key areas. We also prioritize and incorporate spill reduction opportunities into site-specific environmental plans. For example, in our Malaysian upstream operation, we launched a Field-Wide Spill Prevention Program in 2007 to promote more effective on-the- deck cleaning.

We are particularly proud of our marine spill performance in 2007. There were no spills from ExxonMobil-operated vessels, and spills from our marine operations—whether operated by ExxonMobil or not—amounted to a fraction of a teaspoon of oil per million barrels transported.
