ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT • 25 SAFETY COMMUNITY PEOPLE GOVERNANCE ENVIRONMENT Our Approach to Environmental Management 1 MILLION METRIC TONS PER YEAR CAPTURED IS EQUIVALENT TO THE ANNUAL ENERGY CONSUMED BY MORE THAN 125,000 AMERICAN HOMES 6 More Than 1 Million Metric Tons of CO 2 Captured Each Year In 2013, our refinery in Port Arthur, Texas , became the first industrial site in the U.S. to sucessfully host a large-scale carbon capture project, and it remains the only U.S. refinery doing so, with more than 1 million tons captured each year. Two steam methane reformer units, owned by a provider that produces hydrogen from natural gas for the refinery, were retrofitted to capture the carbon dioxide generated from hydrogen production. Responsibility: refinery staff dedicated to environmental excellence and risk mitigation. Risk Assessment: formal risk assessments documented, implemented and maintained at sites, including hazard identification, risk evaluation, analysis and mitigation. Compliance: assurance with legal requirements, communicating and monitoring changing regulations. Objectives and Continuous Improvement: progress on environmental management, including strategic planning, goals and objectives, is reviewed at least annually. Record Keeping: ensure documents are identified, managed and maintained. Training: ensure all employees are skilled, trained and competent to perform duties in an environmentally responsible manner. Monitoring and Communication: operations and activities measured and monitored, assessing the implementation and effectiveness of operational controls, and tracking and evaluating environmental performance. Audits and Assessments: internal and independent audits and verifications are conducted to identify the adequacy and effectiveness of environmental controls, regulatory compliance and excellence vision. 6 Source: U.S. Environmental Protection Agency (EPA) Greenhouse Gas Equivalencies Calculator.
