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 demonstrates solid operational emissions reductions and transparent governance, but lacks comprehensive Scope 3 absolute targets and holds weak positions on nature, water, and climate lobbying. Mixed trade association alignment and unresolved tensions between stated climate commitments and advocacy for high-GHG energy policies undermine credibility.
Verizon Communications scores 38/100 on the SINK sustainability index (Below expectations). Verizon reports comprehensive emissions data with third-party assurance, but Scope 3 rose in 2023 while renewable energy claims rest on financial instruments rather than physical grid decarbonisation. Recent environmental violations, ongoing lead-cable contamination lawsuits, and active opposition to climate policy via industry groups undermine credibility.
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.
