Creating Shared Value

In practice, the concept of creating shared value involves assessing all the potential ways that our actions impact others both inside and outside our operational fence lines. Our commitment to creating shared value means being accountable for our actions to a broad range of stakeholders – our people, business partners, customers, communities, governments, shareholders and others who have a stake in how we operate.

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



In one form or another, our company has been helping fuel America since the 1800s. Seriously.
