WILLIAMS COMPANIES, INC.

Environmental Stewardship and SustainabilityEnvironmental sustainability at Williams is about driving long-term financial success, providing affordable and reliable energy while being good stewards of our natural resources, and leveraging our natural gas strategy and infrastructure to build a clean energy future. Our entire Board and each Board Committee plays a role in oversight. Our Governance and Sustainability Committee oversees (a) our ESG strategy and policies, including matters that may arise due to climate change and energy transition and (b) reviews current and emerging issues, trends, major legislative and regulatory developments, stockholder engagement, or other public policy matters related to ESG. At every regularly scheduled Governance and Sustainability Committee meeting, management provides an ESG report, as well as updates on the development of our annual Sustainability Report. Our Audit Committee shares responsibility with the Governance and Sustainability Committee for ESG oversight, focusing on matters concerning numerical integrity. Our Compensation Committee modifies the compensation program as needed to help progress our sustainability-related goals. Our Environmental, Health and Safety Committee monitors environmental, health and safety matters, including compliance with applicable and proposed legislation, regulations, and orders; conformance with industry standards and best practices; and environmental sustainability. Finally, our full Board oversees management of sustainability-related risks and opportunities, integration of ESG into our corporate strategy, and reviews our Sustainability Report prior to publication. We have a Sustainability Steering Committee comprised of leaders from across the Company, including operations, project execution, and corporate strategy. These leaders champion the development and implementation of sustainability initiatives across our business and provide directional feedback in the preparation of our Sustainability Report and other sustainability-related content. Our Director of Business Development and Sustainability leads the development and execution of our sustainability integration strategy, including engaging with external stakeholders to understand sustainability expectations and communicating our performance and management practices. Key focus areas for 2025 included: emissions reduction efforts, permitting reform, and our growing power innovation business.COMMITTED TO SUSTAINABLE OPERATIONSWilliams strives to preserve the environment for future generations by avoiding, minimizing and mitigating potential impacts on biodiversity and land during the routing, siting, construction, maintenance, remediation, and retirement of pipelines and facilities. We conduct Geographic Information System (GIS) analyses, computer-based reviews, and site-specific surveys to pinpoint sensitive environmental, cultural, and historic areas. In addition to working with permitting agencies, Williams collaborates with interest groups, biodiversity and land mapping experts, community organizations, and land management agencies to develop appropriate impact minimizations, restoration, and offset plans. Williams is committed to strong landowner engagement and partnership, responsibly installing pipelines during construction, and, when assets are retired, restoring the land to its original state or beyond, while creating opportunities for beneficial reuse.Williams understands water is a precious resource, and we work to use it responsibly during asset construction, operation, and retirements. Williams’ environmental inspection, compliance and corrective action programs, such as our Environmental Assessment Program, help us adhere to all relevant environmental laws and regulations regarding water use. We try to avoid construction through wetlands and sensitive streams, reduce workspaces in or near water features, and monitor operational water usage and the impact of our operations on water-stressed regions.

We continuously work to reduce our operational GHG emissions that occur across our assets. Our efforts to reduce operational GHG emissions include operating our assets efficiently through preventative maintenance, conducting leak detection and repair assessments, process improvements, such as implementing recompression measures and evaluating usage of gas drivers versus electric motors. Additionally, we are focused on modernizing our facilities, including installing emission reduction equipment such as compressor vent gas recovery systems and emission control devices, which are included in our Emissions Reduction Program. We prioritize accurate measurement and transparent communication about our emissions to help our subject matter experts develop emissions reduction strategies. In our Sustainability Report, you can find our GHG emissions totals and methane intensities by industry segment.

Williams collaborates with peer companies, technology enablers, and trade associations to uncover and implement innovative best practices as well as advocate for sound, actionable energy and decarbonization policies. Some of these initiatives include NextGen Gas, where we are offering end-to-end certified gas deliveries, where natural gas is securely measured, tracked, and independently verified; carbon capture and sequestration (CCS), where we are developing infrastructure required to capture, transport, and sequester CO 2; solar and battery storage, where we are evaluating the development of behind-the-meter photovoltaic solar and battery systems to offset current electricity consumption at existing facilities and looking to scale these projects for third-party energy demand; and renewable natural gas, where we are constructing new interconnects and pipeline extensions to make use of low or negative carbon substitutes for fossil-derived natural gas that comes from landfill waste, municipal water treatment facilities, livestock farms, or food waste operations.
