We believe sustainability is a process that creates shared value by working to help society achieve economic growth, environmental preservation and resource conservation, thereby creating shared value with our many stakeholders.

What Sustainability Means to Us


We view sustainability as the fundamental process of shared value creation, in which strategic investment and innovation help our society achieve economic growth, environmental preservation and resource conservation to address the needs of future generations. Sustainability at MPC consists of five areas: leading in sustainable energy, conserving natural resources and reducing waste, creating shared value and opportunity, promoting safety and operating with integrity.
