AT&T scores 3 points higher than Verizon Communications on SINK's sustainability index.
AT&T is more sustainable according to SINK's open sustainability index, scoring 41/100 vs Verizon Communications's 38/100 — a difference of 3 points.
AT&T scores 41/100 on the SINK sustainability index (Below expectations). AT&T has strong operational emissions reduction (52% absolute cut since 2015) and comprehensive Scope 1/2 reporting with third-party assurance. Weaknesses are clear: no Scope 3 absolute reduction target, no RE100 commitment despite renewable energy claims, minimal nature/biodiversity disclosure, and mixed climate lobbying including opposition to Texas environmental regulations.
Verizon Communications scores 38/100 on the SINK sustainability index (Below expectations). Verizon reports comprehensive emissions data with SBTi-validated targets but relies heavily on financial instruments (REPAs, RECs) rather than physical grid decarbonization. Scope 3 emissions rose year-on-year despite operational reductions. Lead cable contamination lawsuits and hazardous materials violations expose real environmental harm; aggressive climate policy opposition through industry groups contradicts net-zero commitments.
Both companies are rated on the same 10-question SINK rubric: Scope 1/2/3 carbon footprint, energy source, nature and biodiversity, resource use, water, emissions trajectory, science-based targets, transparency, and controversies. Scores are 0–100, based on public data, and fully reproducible.
