Deutsche Telekom has achieved extraordinary operational emissions cuts (94% Scope 1+2 reduction since 2017) and holds SBTi net-zero validation, but Scope 3 reduction velocity is insufficient for its 2030 targets. Nature and water impacts remain largely unquantified despite acknowledged dependencies. Trade association misalignment undermines climate advocacy.
Deutsche Telekom AG scores 45/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Deutsche Telekom AG joint 258th of 847 companies scored, and 11th of 18 in Telecommunications.
