We are committed to operating our business in an environmentally responsible way. Refining is an energy-intensive business and reducing overall energy consumption and increasing energy efficiency are key priorities across our refinery locations.
All four of our refineries are in the top 50% of refineries in the United States in terms of energy efficiency. We are committed to making continuous improvements in our performance, and each of our refineries have programs under way to reach their goals.
We also recognize our potential impact in other environmental areas, including water usage and waste, and are currently developing methods to track those impacts consistently across our businesses. Our Environmental, Health, Safety and Security Policy outlines our vision of excellence for a workplaces that is safe, secure, injury-free, and protective of the environment, and the steps we will take to reach our vision.
