Microsoft’s 2024 AI Expansion Sparks 25% Surge in Carbon Emissions

Topline

Microsoft reported on Thursday that its carbon emissions rose sharply last year as the company built new data centers to support burgeoning AI demand. The increase represents a setback for the tech giant’s climate targets, while industry analysts warn that AI-driven infrastructure growth could double global data‑center emissions over the next decade.

Key Facts

Microsoft emitted 20 million metric tons of carbon‑dioxide equivalent last year—a 25 % increase from the 16 million metric tons recorded in 2024—according to its annual sustainability report.

Microsoft President Brad Smith and Chief Sustainability Officer Melanie Nakagawa noted that AI infrastructure is intensifying demand for energy, water, land and materials, but “sustainability solutions are not scaling fast enough to meet demand.” They described the resulting tension as both real and productive.

The company also said its reported emissions were affected by a decision to pause purchases of renewable‑energy credits, which firms typically use to offset electricity‑related emissions.

Big Number

300 million metric tons. That is the amount of global carbon‑dioxide emissions from data‑center electricity use the International Energy Agency expects by 2035, nearly double the 180 million tons emitted today.

Tangent

Officials in Cheyenne, Wyoming, have linked the construction of a Meta data center to a rare bacterium found in the city’s wastewater treatment facility. The bacterium was not detected in drinking water, prompting the Cheyenne Board of Public Utilities to halt the acceptance of industrial water discharge from future data‑center projects.

Key Background

Microsoft pledged in 2020 to become carbon‑negative by 2030, but recent rapid expansion of AI infrastructure has strained that goal. The firm has announced several data‑center projects, including a $3 billion site in Wisconsin billed as the world’s most advanced AI data center. Rival tech giants are also confronting rising emissions: Alphabet’s emissions climbed 48 % between 2019 and 2024, driven by data‑center growth and AI demand, and the company acquired clean‑energy startup Intersect Power to help power its facilities.
