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 See 2020 gross production. Applies to all intensity metrics based on total gross production.
e Increase in VOCs is primarily due to accounting changes in the Resource Plays.
f Excludes recycled water volumes.
g Data includes spills outside of secondary containment ≥ 1 barrel.
h 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. In 2019, two produced water spills of ~47,500 barrels accounted for total volume.
i Workforce statistics reflect year-end data.
j Data does not include total retirement rates of 4.6%, 1.3%, 2.4%, 2.9% and 5.1% for 2020, 2019, 2018, 2017 and 2016, respectively.
k Minority designation defined by Equal Employment Opportunity EEO-1 report categories.

These tables contain data relevant to Marathon Oil’s governance, environmental, safety, workforce and social 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). The gas capture percentage is the estimated volume of wellhead gas flared, over the estimated volume of gross gas produced. Except as noted, metrics in this table represent global performance.
