In 2025, Northrop Grumman reported 122,483 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 Northrop Grumman includes a breakdown across 1 of the 15 Scope 3 categories defined by the GHG Protocol, up from 0 in 2024, reflecting improved emissions accounting practices and greater transparency across the company's value chaina
In 2025, Northrop Grumman reported total Scope 3 emissions of 122,483 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 100% of these emissions originated from upstream activities such as purchased goods and capital goods, while 0% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Northrop Grumman's Scope 3 emissions have decreased by 74.47%, reflecting a declining long-term trend in Scope 3 emissions over time.ac
In 2025, Northrop Grumman 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 Northrop Grumman's Scope 3 emissions were:a
In 2025, Northrop Grumman reported Scope 1 greenhouse gas (GHG) emissions of 294,567 tCO₂e and total revenues of USD 41,954 millions. This translates into an emissions intensity of 7.02 tCO₂e per millions USD.a
In 2025, Northrop Grumman reported a Scope 1 emissions intensity of 7.02 tCO₂e per millions USD. Compared to the peer group median of 7.63, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Northrop Grumman ranked 10 out of 22 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Northrop Grumman is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Northrop Grumman reported a total carbon footprint of 874,428 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 24.01% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.ab
The largest contributor to Northrop Grumman's total carbon footprint was Scope 2 emissions, accounting for 52.31% of the company's total carbon footprint, followed by Scope 1 emissions at 33.69%.a
