The AI gold rush has a carbon problem. Microsoft, Google, and Amazon all reported significant jumps in greenhouse gas emissions, driven almost entirely by the insatiable energy appetite of their expanding AI data center networks.
Microsoft’s emissions climbed roughly 25% year-over-year to approximately 20-21 million metric tons. Google wasn’t far behind with an 18% increase. And Amazon posted a 16% rise to about 81 million metric tons, marking its largest annual emissions jump since the company made its net-zero pledge back in 2019.
The numbers behind the power grab
Microsoft’s energy consumption has surged 168% since 2020, a period that coincides with the company’s aggressive push into AI infrastructure through its partnership with OpenAI.
All three companies pointed to the same culprits: data center construction, skyrocketing electricity demand, and the broader buildout required to support AI workloads at scale.
Microsoft says it will be carbon negative by 2030. Google is maintaining the same 2030 target for carbon neutrality. Amazon is aiming for net-zero by 2040.
Carbon credits and nuclear bets
Big Tech’s appetite for carbon credits has gone from modest to extraordinary. Purchases across these companies escalated from 14,200 credits in 2022 to approximately 68.4 million by 2025. That’s a 181% year-over-year growth rate.
Tech companies are also actively pursuing agreements to secure carbon-free power from nuclear facilities, including projects involving Three Mile Island and Kairos Power.
Where crypto mining fits in
IREN, a company that previously operated as a Bitcoin mining operation, secured a $9.7 billion AI cloud contract with Microsoft. The deal essentially repurposes crypto mining sites to handle AI workloads instead.
