Microsoft announced a 25 percent increase in its greenhouse gas emissions for the latest fiscal year, as stated in its new sustainability report released Thursday. The figure aligns with similar trends from Google and Amazon, highlighting a growing challenge for the tech sector as it expands power-hungry data centers to support artificial intelligence.
The report, signed by vice chair and president Brad Smith and chief sustainability officer Melanie Nakagawa, attributes the rise primarily to the expansion of data center infrastructure. A significant portion of the increase is tied to Scope 2 emissions from purchased energy, accounting for 13 percent of Microsoft's total. The company notes it matched 100 percent of its electricity consumption with carbon-free sources, but data center construction continues to accelerate.

Data centers push net-zero goals further out of reach for big tech
Data centers, essential for training and running AI models, are pushing many tech companies away from their net-zero targets. Google reported an 18 percent rise in annual emissions, its largest single-year increase, while Amazon saw a 16 percent jump. To counter this, Microsoft has shifted its offset strategy, moving away from unbundled renewable energy certificates, which have been criticized as greenwashing. According to Danny Cullenward, a researcher at the University of Pennsylvania, this is a commendable move because it prioritizes investments in new clean electricity through long-term power purchase agreements.

New deals with Chevron and Stargate raise environmental risks
Despite its stated commitment, some recent Microsoft initiatives could worsen its carbon footprint. Last month, the company formalized a partnership with Chevron to build a gas-powered plant in West Texas to supply a future data center. Permits indicate the plant could emit over 11.5 million tons of CO2 equivalent annually, more than the entire state of Rhode Island. Additionally, permits for the Stargate campus in Abilene, Texas, show a plant emitting over 7.8 million tons, and a nonbinding letter of intent for a West Virginia data center powered by off-grid gas could add over 11 million tons. Melanie Nakagawa confirms that Microsoft is exploring various mitigation options consistent with its sustainability ambitions.

The company reiterates its goal to become "carbon negative" by 2030. As Smith and Nakagawa write, "The global race for AI is increasing demand for energy, water, land, and materials. We have a responsibility to help ensure that technology strengthens, rather than strains, the systems and communities on which it depends." However, the numbers indicate a challenging path.
