In 2024 we produced our 2023 Sustainability Report, and continued to advance our strategic plan to incorporate sustainable technology into our business, focused on projects that will provide meaningful reductions in our carbon footprint, while also providing value to our shareholders and customers. During 2024, the Company received a $4 million cost-share award from Department of Energy’s Office of Clean Energy Demonstrations for Phase I of the Carbon Capture Pilot at Big Spring Refinery project. The Company received a contract modification in December 2024 that obligates the full $95 million for all four phases of the carbon capture technology project. The project aims to capture 145,000 metric tons of carbon dioxide each year —equivalent to the annual emissions of more than 34,500 gasoline-powered cars.

Our Governance Guidelines recognize that the Board has overall responsibility for the oversight of the Company’s ESG activities, including oversight of climate-related risks and opportunities, including broad emissions reduction targets and the Company’s sustainability reports. The Board has delegated oversight of certain ESG activities to its standing committees, as set forth in each committee’s respective charter, and from time to time the Board may refer specific issues to the committees at the Board’s discretion.
