In 2025, the total operational greenhouse gas (GHG) emissions of Exxon Mobil amounted to 113,000,000 metric tons of CO2 equivalent. This figure includes both direct emissions from owned or controlled sources (Scope 1) and indirect emissions from purchased energy (Scope 2).a
Compared to 2024, the total operational greenhouse gas (GHG) emissions of Exxon Mobil increased by 0.89%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of Exxon Mobil were 104,000,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Exxon Mobil's Scope 1 emissions have increased by 2.97%, reflecting a rising long-term trend in Scope 1 emissions over time.ac
Compared to the previous year (2024), Exxon Mobil's Scope 1 emissions remained relatively stable, indicating that Exxon Mobil's emissions have plateaued with no significant change in its operational footprint.a
In 2025, Exxon Mobil reported Scope 2 greenhouse gas (GHG) emissions of 7,000,000 tCO₂e using the market-based method and 9,000,000 tCO₂e using the location-based method.a
Since 2019, Exxon Mobil's Scope 2 greenhouse gas (GHG) emissions (Location-Based) have increased by 12.5%, reflecting a rising long-term trend in Scope 2 emissions over time.ac
Compared to the previous year (2024), Exxon Mobil's Scope 2 emissions (Location-Based) rose by 12.5% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energya
In 2025, Exxon Mobil reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Exxon Mobil reported 700,000,000 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of Exxon Mobil includes a breakdown across 1 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2024, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2025, Exxon Mobil reported total Scope 3 emissions of 700,000,000 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 0% of these emissions originated from upstream activities such as purchased goods and capital goods, while 100% came from downstream activities like product use, distribution, and end-of-life treatment.a
Compared to the previous year (2024), Exxon Mobil's Scope 3 emissions remained relatively stable, indicating that Exxon Mobil's emissions have plateaued with no significant change in its value chain footprint.ab
In 2025, Exxon Mobil reported emissions for 1 out of the 15 Scope 3 categories defined by the GHG Protocol.a
The limited disclosure restricts visibility into specific emission sources across the company's value chain.
In 2025, the largest contributors to Exxon Mobil's Scope 3 emissions were:a
In 2025, Exxon Mobil reported Scope 1 greenhouse gas (GHG) emissions of 104,000,000 tCO₂e and total revenues of USD 323,905 millions. This translates into an emissions intensity of 321.08 tCO₂e per millions USD.a
In 2025, Exxon Mobil reported a Scope 1 emissions intensity of 321.08 tCO₂e per millions USD. Compared to the peer group median of 331.41, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Exxon Mobil ranked 12 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Exxon Mobil is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Exxon Mobil reported a total carbon footprint of 813,000,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 3.44% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.ab
The largest contributor to Exxon Mobil's total carbon footprint was Scope 3 emissions, accounting for 86.1% of the company's total carbon footprint, followed by Scope 1 emissions at 12.79%.a
