T-Mobile US

T-Mobile is a telecommunications company based in the United States, with its headquarters in Bellevue, Washington. The company offers wireless services, 5G connectivity, home internet, prepaid brands, and business communications. Due to its network of offices, retail locations, and network facilities, water use is relevant to T-Mobile's ESG performance. However, its direct operations are less water-intensive compared to those of manufacturing or data center-focused companies.

T-Mobile's most notable water sustainability achievement is the consistent reduction in reported water consumption. Total water consumption decreased from 862,142 cubic meters in 2022 to 738,996 cubic meters in 2025, representing a reduction of 123,146 cubic meters, or approximately 14.3%.

Unlike its peers, T-Mobile locates water almost entirely in its supply chain rather than its own facilities. Its Responsible Sourcing Policy sets water expectations, and EcoVadis scorecards rate Tier 1 suppliers on water, wood, minerals, and other resources. Nothing downstream of that screening is measured, however: no supplier water savings, site initiatives, reuse volumes, discharge, or stress exposure. The result is a procurement control with no water outcome attached.
