Charter's footprint was 2,494,640 tCO2e in 2023, the sum of its printed Scope 1, market-based Scope 2 and Scope 3 lines, up from 2,442,564 t in 2022. These figures, from its last ESG report, predate the Cox combination and are not independently audited. Its Scope 3 covers only set-top boxes and small network equipment, mobile devices and air travel, so the size deduction for an incomplete footprint (0.70x) applies. It names no renewable supply contract and gives no renewable share. Its only climate target, carbon neutrality in its own operations by 2035, is self-set. It recovered 30,475 tonnes of equipment through take-back in 2023.
