Valero continues working to meet our nation's growing demand for clean fuels. Over the years, Valero has invested billions of dollars to produce the clean fuels that adhere to new clean fuels standards while continuing to meet the growing demand of U.S. consumers.

We are investing in the latest technology to improve combustion and energy efficiency at our refineries. This will reduce fuel consumption and carbon dioxide emissions over the next several years.

Much of Valero's emission reductions are a result of major investments in state-of-the-art emission- reduction technology. For example, Valero invested nearly $700 million to construct state-of-the-art scrubber units at our Delaware City refinery. Two scrubber units went online at the refinery in 2006. Valero also has scrubber units -- which reduce sulfur dioxide emissions by more than 93 percent -- at 10 of its refineries.

Through careful scientific, economic, and technical analysis, the company will continue to work with all stakeholders to develop long-term measures that protect the environment.

Valero will also continue to be on the forefront of environmental technology, and we will remain committed to sharing best practices from within our operations and throughout the industry.
