Corporate Citizenship

At Marathon Petroleum Corporation (MPC), we believe that doing the right thing is the right way to conduct our business.

In practice, the concept of corporate citizenship involves assessing all the potential ways that our actions impact others both inside and outside our operational fence lines. MPC's commitment to corporate citizenship means being accountable for our actions to a broad range of stakeholders -- investors, employees, customers, suppliers, communities, business partners, and others who have a stake in how MPC operates.

MPC has long-established core values associated with health and safety, diversity and inclusion, environmental stewardship and honesty and integrity. All of these corporate values are vital to MPC's financial performance and to our corporate image and reputation.

MPC manages its business to promote sustainable social, environmental and economic benefits to all stakeholders wherever we operate. By doing so, we create long-term value both for MPC and also in the communities where we work and live.
