Microsoft reported a 25% increase in its carbon emissions for 2025, reaching 20 million metric tons of carbon dioxide equivalent, according to its annual sustainability report released on Thursday. This rise marks a setback for the company's climate goals as it expands its data center operations to meet growing demand for artificial intelligence (AI) services.
Key Details
The company's emissions increased from 16 million metric tons in 2024, reflecting the energy-intensive nature of AI infrastructure development. Microsoft President Brad Smith and Chief Sustainability Officer Melanie Nakagawa acknowledged that while AI is driving demand for energy and resources,
sustainability solutions are not scaling fast enough to meet demand.
Additionally, Microsoft paused its purchases of renewable energy credits, which are used to offset emissions from electricity consumption. This decision contributed to the surge in reported emissions. The International Energy Agency projects that global carbon dioxide emissions from data center electricity use could reach 300 million metric tons by 2035, nearly doubling from 180 million tons today.
Background
Microsoft's commitment to becoming carbon negative by 2030 has faced challenges as the rapid expansion of AI infrastructure continues. The company has announced several data center projects, including a $3 billion facility in Wisconsin.

The increase in emissions could raise scrutiny on technology companies regarding their environmental impact, potentially influencing regulatory measures. Investors may react to this news by reassessing the sustainability practices of major tech firms, particularly those heavily invested in AI infrastructure. Watch for Microsoft’s upcoming quarterly earnings report, which may provide further insight into its sustainability strategies and future emissions outlook.
