Energy efficiency improvements

Producing fuel and petrochemicals requires significant amounts of energy. In 2010, our operations consumed approximately 1.47 billion gigajoules of energy. Since 2000, we have used our Global Energy Management System (GEMS) to systematically identify and address operational efficiency opportunities.

We remain on track to achieve our goal of improving energy efficiency across our worldwide refining and chemical operations by at least 10 percent between 2002 and 2012. We have improved energy efficiency by an average of 7.5 percent in refining and more than 10 percent in chemical since 2002. At our Baton Rouge Chemical Plant in Louisiana, we are upgrading existing equipment to improve energy efficiency, reliability, and raw material flexibility. We anticipate the upgrades will be completed by the end of 2011 and will reduce annual GHG emissions by approximately 80,000 metric tons. At Beaumont, Texas, we constructed a steam line from the chemical plant to the refinery, where there is a demand for steam. The line will reduce annual costs by more than $1.5 million and will reduce GHG emissions by 21,000 metric tons per year, or the equivalent of removing 4000 cars from U.S. roads.

In 2010, the four buildings at our Brookhollow campus in Texas received U.S. Environmental Protection Agency ENERGY STAR Awards, the national symbol for superior energy efficiency and environmental protection. Overall, the Brookhollow campus has reduced its total energy consumption by 27 percent from 2007 through 2010, or by 13,320 gigajoules.

Our Global Real Estate and Facilities group has been working on a Green Assets initiative to minimize the environmental footprint of our assets by utilizing best practices from building standards such as LEED, BREEAM, and Green Star. The group also developed design criteria to reduce energy consumption in facilities in the United States, which are now being expanded internationally.
