Corporate Citizenship

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. Our 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 we operate.

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 our financial performance and to our corporate image and reputation.
