AI's Environmental Impact: Emissions Rise at Microsoft and Google Due to Data Centers
Key points
- Microsoft's emissions rose 30% since 2020 due to AI data centers.
- Google's emissions surged 50% since 2019, 13% in 2023, driven by AI.
- IT accounts for 2-4% of global emissions, comparable to aviation.
- Recommendations include using smaller models and low-carbon electricity for compute.
Rising Emissions from AI Infrastructure
Microsoft's 2024 environmental report indicated a 30% increase in total carbon emissions since 2020, largely attributed to the construction of data centers supporting AI demand. Google's emissions also saw a substantial rise, surging approximately 50% since 2019 and 13% in 2023 alone, primarily due to artificial intelligence operations.
IT's Contribution to Global Emissions
Charles Humble, speaking at GOTO Copenhagen, stated that the IT industry is responsible for about 2-4% of all global emissions. This figure is comparable to the aviation industry's 3% contribution. The International Energy Agency (IEA) reported that the combined electricity use of Amazon, Microsoft, Google, and Meta more than doubled between 2017 and 2021, reaching around 72 terawatt-hours in 2021.
Electricity Consumption in Data Centers
The IEA estimated global data center electricity consumption in 2022 to be between 240 and 340 terawatt-hours, representing 1% to 1.3% of global electricity demand. When combined with network electricity consumption, the total reaches approximately 700 terawatt-hours, which is similar to Brazil's total electricity consumption in the same period.
Recommendations for Sustainable AI
Humble emphasized that sustainability should be a top-level architectural concern in AI development. His recommendations include utilizing pre-built and smaller models, running compute operations in regions with abundant low-carbon electricity, and training AI models using renewable energy sources. He also suggested evaluating the necessity of training new models from scratch and considering demand shaping.
