Our Board is committed to effective oversight of our climate-related risks and progress across our sustainability initiatives. This commitment is reflected in the oversight responsibilities for these matters which are shared by our standing committees. In particular, the Risk Committee periodically reviews and discusses with Company management various environmental, social, and governance (ESG) considerations, which include environment, safety, and sustainability matters. With the assistance of the Company's Compliance Department, the Risk Committee periodically assesses management of sustainability-related risks. [...] On a day-to-day basis, our sustainability efforts are managed by our respective operational departments with oversight by our ESG working group, which interacts regularly with our third-party ESG consultant, as well as our management-level ESG Steering Committee. This cross-functional committee is composed of Executive Management including our Chief Executive Officer, Chief Operating Officer, and Chief Financial Officer, as well as officers from Operations, Finance, Safety, Compliance, Human Resources, Legal, Equipment/Maintenance, Real Estate, Marketing, and Information Technology. Our operational leaders are responsible for measuring and monitoring ESG matters and for reviewing and applying stakeholder feedback and insights. To facilitate transparency and accountability in our ESG program, members of our ESG Steering Committee regularly report our ESG initiatives and progress to the Risk Committee, and from time to time the full Board of Directors.
