Marathon’s CSR Performance Data

This table contains data relevant to Marathon’s ESGW performance. We understand that the accuracy of the data is inherently constrained by differing reporting rules, definitions, estimating methods and other factors. Marathon endeavors to strengthen global data reporting systems and methodologies but recognizes as accuracy is improved, corrections will be needed periodically. Adjustments to previously reported data are noted where applicable. In this table, some totals may not equal the sum of their components and separate calculation of other data may be affected due to independent rounding. The metrics below are for operations under direct Marathon management and operational control. GHG emissions are estimated using industry guidelines (API’s Compendium of Greenhouse Gas Emissions Methodologies for the Oil and Gas Industry and the API, IPIECA and OGP Petroleum Industry Guidelines for Reporting Greenhouse Gas Emissions). Except as noted, metrics in this table represent global performance.
