Datacentres drive up big tech's carbon emissions to a third of those of France
TL;DR
Big tech companies Microsoft, Amazon, and Google have seen their carbon emissions rise by nearly 20% due to increased datacentre construction. In the financial year ending March 2026, their emissions reached 119 million metric tonnes of CO₂ equivalent, comparable to a third of France's total emissions.
✦ Why It Matters
Engineers should evaluate energy-efficient datacentre designs and consider renewable energy sources for new projects.
Key Takeaways
- Assess the carbon footprint of your cloud infrastructure projects.
- Explore energy-efficient technologies for datacentre design.
- Incorporate renewable energy sources in new datacentre constructions.
- Stay informed about regulatory changes regarding emissions in your region.
Full Summary
Microsoft, Amazon, and Google are experiencing a significant rise in carbon emissions, primarily driven by a surge in demand for cloud services, including data storage and server operations for AI applications. In the fiscal year ending March 2026, these companies emitted approximately 119 million metric tonnes of CO₂ equivalent, a notable increase from 101 million metric tonnes the previous year.
This rise in emissions is largely attributed to the construction of new datacentres to support the growing needs of AI technologies, such as chatbots. The emissions from these tech giants now represent about a third of France's total carbon output.
Their climate goals of achieving net zero emissions are increasingly challenged by this construction boom. Engineers and researchers must consider the environmental impact of scaling cloud infrastructure and explore sustainable alternatives.
