AT&T's climate performance is undermined by rising Scope 3 emissions and weak renewable energy adoption despite Scope 1–2 reductions. Lead-cable litigation, active lobbying against climate policy, and incomplete waste tracking expose governance gaps.
AT&T scores 37/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified October 2026.
That places AT&T joint 435th of 847 companies scored, and 17th of 18 in Telecommunications.
