Tech Giants' Emissions Surge Amid AI Datacentre Expansion

Microsoft, Amazon, and Google reported a significant increase in carbon emissions due to a boom in datacentre construction, with their collective emissions rising nearly 20% to 119 million metric tonnes of CO₂ equivalent in the year ending March 2026. This increase is attributed to the growing demand for cloud services, particularly for AI applications. Microsoft alone saw a 25% rise in emissions, reaching 20 million metric tonnes, while Google and Amazon reported increases of 18% and 16%, respectively. The surge in emissions has raised concerns about the sustainability claims made by these companies. Despite the increase, all three companies maintain their goals of achieving net-zero emissions, with Google and Microsoft targeting 2030 and Amazon aiming for 2040. The construction of AI-focused datacentres is expected to continue, with projected spending of $765 billion in 2026. This trend highlights the environmental impact of the tech industry's rapid expansion in AI infrastructure.

Key Points: • Microsoft, Amazon, and Google collectively emitted 119 million metric tonnes of CO₂e in 2026. • Microsoft's emissions increased by 25% due to datacentre expansion, reaching 20 million metric tonnes. • The tech giants aim for net-zero emissions by 2030 or 2040 despite rising carbon footprints.
