Amazon retains second place in 2026 US retail rankings, emissions surge
AMZN•Amazon ranked second behind Walmart in the 2026 US retail rankings, solidifying its top-two position. It also reported a sharp rise in greenhouse gas emissions as accelerated AI infrastructure expansion hindered progress toward its carbon-neutrality pledge.
1. Top-two position in US retail
Amazon secured the second spot in the 2026 US retail rankings, trailing only Walmart. The company maintained its leading online and in-store presence, driven by strong customer demand and expanded delivery networks.
2. AI infrastructure drives emissions rise
Amazon disclosed a sharp year-over-year increase in greenhouse gas emissions, attributing the spike to rapid buildout of data centers and AI compute facilities. This surge has set back its carbon-neutrality timeline as infrastructure expansion outpaces planned offset measures.
