The AI boom is creating a carbon problem. Microsoft, Google, and Amazon all reported significant jumps in greenhouse gas emissions, driven by the energy demands of their expanding AI data center networks.
Microsoft's emissions climbed roughly 25% year-over-year to about 20 million metric tons. Google's increased 18%. Amazon saw a 16% rise to 81 million metric tons, its largest annual jump since its 2019 net-zero pledge.
The surge stems from data center construction and skyrocketing electricity demand to support AI workloads at scale. Microsoft's energy consumption has risen 168% since 2020, coinciding with its AI push via its OpenAI partnership.
All three companies maintain ambitious carbon neutrality goals: Microsoft and Google target 2030, while Amazon aims for 2040.
To offset emissions, the firms' purchases of carbon credits have exploded from 14,200 in 2022 to approximately 68.4 million by 2025. They are also pursuing carbon-free power from nuclear facilities.
In a notable industry shift, former Bitcoin mining operation IREN secured a $9.7 billion AI cloud contract with Microsoft, repurposing its infrastructure for AI workloads.
