Air emissions

We continue to seek opportunities to reduce the environmental impacts from our operations and our products.

Our combined emissions of volatile organic compounds (VOCs), sulfur dioxide (SO2) and nitrogen oxides (NOx) have decreased more than 40 percent over the past 10 years across all of our operations. Our Baytown (Texas) refining and petrochemical complex has also achieved near double-digit improvements in energy efficiency and air quality during the past decade. Despite its size and complexity, the Baytown Refinery now uses energy more efficiently than 90 percent of all other U.S. refineries. Over the past decade, energy efficiency across the Baytown complex has improved by 10 percent, and NOx and VOC emissions have been reduced by 46 percent and 40 percent, respectively. During this same period, air-related incident performance has improved by 64 percent.

    “As a community partner in Baytown for 95 years, we are proud of our accomplishments. We remain committed to maintaining operational excellence and pioneering new ways to reduce emissions and improve air quality. Our mission is clear: Protect Tomorrow. Today.

In 2014, we completed our clean fuels project at our refinery in Saudi Arabia, a joint venture of ExxonMobil and Saudi Aramco. This project’s desulfurization facilities are designed to cut sulfur levels in gasoline and diesel by more than 98 percent. The ultra-low sulfur fuels produced as a result of this investment will allow for reduced emissions when used in modern engines.
