In 2025, Halliburton completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
However, Halliburton has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.

Compared to 2024, the total operational greenhouse gas (GHG) emissions of Halliburton increased by 0.53%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of Halliburton were 2,649,765 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Halliburton's Scope 1 emissions have decreased by 39.15%, reflecting a declining long-term trend in Scope 1 emissions over time.ab
Compared to the previous year (2024), Halliburton's Scope 1 emissions decreased by 12.33%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.a
In 2025, Halliburton reported Scope 2 greenhouse gas (GHG) emissions of 1,736,743 tCO₂e using the market-based method and 1,741,105 tCO₂e using the location-based method.a
Compared to the previous year (2024), Halliburton's Scope 2 emissions (Location-Based) rose by 29.4% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energya
In 2025, Halliburton reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Halliburton reported 199,914 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 Halliburton includes a breakdown across 0 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, Halliburton reported total Scope 3 emissions of 199,914 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Halliburton's Scope 3 emissions have decreased by 14.2%, reflecting a declining long-term trend in Scope 3 emissions over time.ab
Compared to the previous year (2024), Halliburton's Scope 3 emissions remained relatively stable, indicating that Halliburton's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Halliburton reported Scope 1 greenhouse gas (GHG) emissions of 2,649,765 tCO₂e and total revenues of USD 22,184 millions. This translates into an emissions intensity of 119.44 tCO₂e per millions USD.a
In 2025, Halliburton reported a Scope 1 emissions intensity of 119.44 tCO₂e per millions USD. Compared to the peer group median of 21.31, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Halliburton ranked 19 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Halliburton is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Halliburton reported a total carbon footprint of 4,590,784 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 0.22% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Halliburton's total carbon footprint was Scope 1 emissions, accounting for 57.72% of the company's total carbon footprint, followed by Scope 2 emissions at 37.93%.a
