Amazon's 2025 sustainability report shows total carbon emissions rose 16% to 80.85 million metric tons CO2e, the largest single-year jump since the company started tracking. The increase was driven by record data center capacity additions for AWS and AI workloads. Capital expenditure on property, plant, and equipment surged 59% to $131.8 billion, compressing free cash flow from $32.9 billion to $7.7 billion. Electricity-related emissions grew 34% and supply chain emissions rose 20%, now accounting for 76% of Amazon's total footprint. Amazon matched 100% of electricity consumption with renewable energy for the third straight year via a 42GW portfolio of 712 projects across 30 countries. But the distinction between matching and direct consumption matters: in regions with fossil-heavy grids, the actual electrons powering data centers may still come from coal or gas. Amazon acknowledged that continued demand growth may slow progress toward its Climate Pledge goals. The report highlights a fundamental trade-off for hyperscalers: AI infrastructure buildout drives revenue but pushes absolute emissions higher.
