In 2025, the largest contributors to Western Digital's Scope 3 emissions were:a
In 2025, Western Digital reported Scope 1 greenhouse gas (GHG) emissions of 107,918.3 tCO₂e and total revenues of USD 9,520 millions. This translates into an emissions intensity of 11.34 tCO₂e per millions USD.a
In 2025, Western Digital reported a Scope 1 emissions intensity of 11.34 tCO₂e per millions USD. Compared to the peer group median of 0.34, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Western Digital ranked 21 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places Western Digital among the least efficient performers, with one of the highest emissions intensities in its sector.a
In 2025, Western Digital reported a total carbon footprint of 8,186,018.3 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 6.62% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.ab
The largest contributor to Western Digital's total carbon footprint was Scope 3 emissions, accounting for 90.3% of the company's total carbon footprint, followed by Scope 2 emissions at 8.38%.a
