T-Mobile leads on emissions reduction and renewable energy but has serious gaps in nature, water, and biodiversity reporting. The company has achieved 33% absolute emissions cuts since 2020 and 100% renewable electricity, backed by SBTi-validated net-zero targets. However, no formal biodiversity policy, water footprint data, or quantified nature-risk mapping exists. Weak points undermine an otherwise solid climate programme.
