The greenhouse gas emissions of Amazon.com Inc. and Alphabet Inc.’s Google spiked in 2025, pointing to a growing problem for the hyperscalers: reconciling their climate goals with the massive amount of energy required to power AI, much of it still generated from fossil fuels.

Amazon’s emissions rose 16% from 2024, the company said in a sustainability report released Wednesday. It emitted about 81 million metric tons of carbon dioxide equivalent last year, roughly as much as the emissions from 19 million gas-powered cars on the road. The increase was driven by data center construction and fuel used for deliveries, the report said.

Google’s “ambition-based” emissions — a definition that excludes some parts of its supply chain — climbed 18% overall in 2025. Its Scope 1 emissions from its own operations, excluding purchased electricity, went up 20% compared to 2024, due in part to its expanding data center portfolio, the company said in its own sustainability report released Tuesday.

Amazon has a goal of reaching net zero by 2040, while Google is targeting 2030. As they balance AI’s power needs with sustainability, the companies report varying degrees of success.

Google’s electricity use went up by 37% last year, but it managed a small drop in its Scope 2 emissions from purchased power due to its sourcing of clean energy. Amazon, by contrast, said its emissions from buying electricity rose 34%.
