Marathon Oil Corporation recognizes that its actions and operations affect a broad range of stakeholders – including communities, investors, employees, customers, suppliers, business partners and host governments. The Company has long-established core values associated with health and safety, environmental stewardship, honesty and integrity, corporate citizenship and a high performance team culture. These are the values that Marathon strives to demonstrate every day.

Marathon's Living Our Values 2008 Corporate Social Responsibility Report provides information on the Company's non-financial performance and its actions to promote sustainable social, environmental and economic benefits.

The Report is based on the Oil & Gas Industry Guidance on Voluntary Sustainability Reporting, published jointly by the International Petroleum Industry Environmental Conservation Association (IPIECA) and the American Petroleum Institute (API). The IPIECA/API Guidance provides a common framework for the petroleum industry to use in reporting non-financial performance. Marathon has included quantitative metrics and qualitative descriptions of policies, programs and practices to provide relevant and meaningful information about the Company's operations and non-financial performance.

Unless otherwise noted, results are reported for those operations under direct Marathon management and operational control, rather than on an equity (net share) basis. Marathon reports estimated greenhouse gas (GHG) emissions from its operated facilities using industry guidelines (API's Compendium of Greenhouse Gas Emissions Methodologies for the Oil and Gas Industry and the Petroleum Industry Guidelines for Reporting Greenhouse Gas Emissions from API, IPIECA and the International Association of Oil and Gas Producers). The accuracy of safety, environmental and workforce data is affected by differing reporting rules, definitions, estimating methods and other factors. Adjustments to previously reported data are footnoted on relevant charts.

Marathon businesses consist of Upstream (exploration and production, oil sands mining and integrated gas) and Downstream (refining, marketing and transportation). Marathon reports performance on a global, corporate-wide basis. Additional information may be reported by business components to furnish more depth. For some measures, results for Speedway SuperAmerica LLC (SSA), Marathon's wholly owned retail marketing subsidiary, are shown separately.
