Amazon's Carbon Emissions Rose 16% in 2025 to 80.85 Million Metric Tons as Data Center Building Accelerated
Amazon's total carbon emissions rose 16% in 2025, to 80.85 million metric tons of CO2 equivalent from 69.55 million metric tons in 2024, according to the company's 2025 Sustainability Report, published in July 2026. Carbon intensity, measured as emissions per dollar of revenue, rose 3% to 112.8 grams of CO2 equivalent per dollar. Amazon said intensity remains 38% below its 2019 baseline, a period in which revenue grew 156%. The report breaks the total into 15.37 million metric tons of Scope 1 direct emissions, 3.74 million metric tons of market-based Scope 2 emissions from purchased electricity and 61.74 million metric tons of other indirect, or Scope 3, emissions.
Amazon said it added more data center capacity in 2025 than any other company globally, to meet customer demand at Amazon Web Services, much of it linked to artificial intelligence. Construction of data centers and the manufacture of servers and other hardware add to Scope 3 emissions through steel, concrete, chips and other materials. Amazon said it matched 100% of the electricity consumed by its global operations with renewable energy for the third consecutive year.
Amazon said its data centers are seven times more water-efficient than the industry average, using air cooling for most of the year, and that it improved water efficiency by 33% in 2025. Outside data centers, Amazon reported a 7% reduction in carbon emissions per shipped unit. Amazon's total footprint is much larger than those of Google or Microsoft because it includes retail, logistics and transport operations as well as cloud computing. Amazon's goal is to reach net zero carbon by 2040, a target set when it co-founded The Climate Pledge in 2019.
Amazon said 62% of its top suppliers now have decarbonization plans, up 23% year on year, and that it provides coaching and access to power purchase agreements to help suppliers cut emissions. Amazon's Scope 1 emissions of 15.37 million metric tons are large for a technology company because they include fuel burned by its own delivery fleet, aircraft and facilities.
