United States Postal Service scores 27/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified October 2026.
That places United States Postal Service joint 647th of 806 companies scored, and 11th of 17 in Shipping / Logistics.
USPS discloses emissions across Scopes 1–3 with multi-year data, but lacks third-party verification and split Scope accounting. Fleet electrification is underway yet slow: only 35,000 of 51,500 ordered vehicles are battery-powered. Scope 3 data was restated after errors; biodiversity and water remain largely unreported.
