a Includes political action committee and corporate contributions.
b Greenhouse gas (GHG) carbon dioxide equivalent (CO₂e) emissions are based on carbon dioxide, methane and nitrous oxide from Marathon Oil-operated facilities only.
c 2017 air emissions have been updated based on a review and resubmittal of emissions data to the EPA.
d Increase in VOCs is primarily due to accounting changes in the Resource Plays.
e Data includes spills outside of secondary containment ≥ 1 barrel.
f Non-oil includes some produced fluids, such as produced water, which may contain trace amounts of hydrocarbons and non-produced fluids such as drilling muds, fracturing and production chemicals. 2019 increase primarily due to two large produced water spills. Total spill volume from these two incidents was ~47,500 bbls of produced water.
g Workforce statistics reflect year-end data.
h Data does not include total retirement rates of 1.3%, 2.4%, 4.2%, 5.1% and 11.1% for 2019, 2018, 2017, 2016 and 2015, respectively.
i Minority designation defined by Equal Employment Opportunity EEO-1 report categories.
These tables contain data relevant to Marathon Oil’s governance, society, environmental, safety and workplace performance. We understand that the accuracy of the data is inherently constrained by differing reporting rules, definitions, estimating methods and other factors. Marathon Oil endeavors to strengthen global data reporting systems and methodologies but recognizes as accuracy is improved, corrections will be needed periodically. In this table, some totals may not equal the sum of their components and separate calculations of other data may be affected due to independent rounding. The metrics above are for operations under direct Marathon Oil 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 IPIECA/API/IOGP Petroleum Industry Guidelines for Reporting Greenhouse Gas Emissions). Except as noted, metrics in this table represent global performance.
