Marathon Oil requires contractors to comply with its Health, Environment and Safety (HES) policies, standards and guidelines, and monitors their HES performance on the job. Together, Marathon Oil and its contractors strive for excellence in health, safety and environmental performance.

Health, Environment and Safety Vision

Marathon Oil's HES Vision is aligned with our Core Values, including those relating to Corporate Governance, Ethics and Integrity, Diversity, and Philanthropy. Business decisions affecting HES are guided by our Code of Business Conduct.

This HES Vision is applicable to Marathon Oil Corporation and all majority-owned subsidiaries. Meeting this commitment is a responsibility shared by everyone, including all employees, contractors and third parties. To realize this vision, we will pursue continuous HES improvement using a suitable "plan-do-check-revise" management system to assess risks, set targets, and measure progress.

Marathon Oil's HES Vision is straightforward:

  • Our people and workplaces are safe
    We are committed to providing safe and healthy workplaces where our employees, contractors and others involved with our operations can work in a secure setting, free of injury or illness.
  • Our operations are clean
    We conduct operations in a manner designed to protect the environment and will work to minimize wastes, emissions and other releases in all of our activities.
  • We practice responsible action wherever we work
    We strive to be a good corporate citizen wherever we operate, in accordance with our Corporate Social Responsibility Position Statement. We maintain high ethical standards, support sustainable business practices, and prepare for and respond accordingly to emergencies that may occur.
