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.
