Since 2000, we have used our Global Energy Management System (GEMS) in the Downstream and Chemical business lines to identify and act on energy-savings opportunities. The GEMS equivalent in the Upstream business is the Production Operations Energy Management System.
From 2002 to 2012, we improved energy efficiency by approximately 10 percent in refining and 12 percent in chemical manufacturing. For example, to help reduce energy consumption at our polymer manufacturing facility in Cologne, Germany, a local team inspected the plant’s steam system to identify areas for potential savings. System improvements reduced steam consumption by 90 tons per month, a 20 percent reduction. At many of our sites, recovering waste heat to generate needed steam provides heat to processes that would otherwise require the combustion of additional fuel. ExxonMobil’s Global Real Estate and Facilities Group has been working on an initiative to reduce the environmental footprint of our offices. In 2012, we continued construction of our new 155-hectare campus just north of Houston, Texas. We carefully considered energy conservation during the design phase of the campus. By optimizing daylight availability and incorporating other energy efficiency measures, we expect to reduce our energy demand in the office buildings by more than 40 percent compared with traditional office buildings. ExxonMobil will install systems to monitor energy consumption to ensure campus buildings achieve a U.S. Environmental Protection Agency Energy Star rating.
In Calgary, Alberta, we are working with the developer of the new Imperial Oil campus to incorporate sustainable design practices into the construction process, buildings and associated green spaces. The use of high-efficiency heating and cooling systems, and lighting and motion sensors will make the campus 40 to 50 percent more efficient than our existing office buildings. In addition, we plan to launch energy conservation, waste minimization and recycling programs when this campus becomes operational. The new Aviation Lubricants Blending & Packaging Plant in Port Allen, Louisiana, will also have a sustainability focus that extends to the design, construction and operational phases.
