Microsoft's greenhouse gas emissions rose by approximately 25 percent in the past year, driven primarily by the expansion of its data center infrastructure.

The company attributes the surge to increased energy consumption from data centers, which power AI operations and contribute significantly to carbon pollution.

While Microsoft claims to have matched 100% of its electricity use with carbon-free sources, new projects involving gas-powered data centers could further elevate emissions.Notable initiatives include partnerships with Chevron for a Texas-based power plant expected to emit over 11.5 million tons of CO2 annually and leasing sites powered by fossil fuels.The company has also shifted away from purchasing unbundled renewable energy certificates, which critics argue are ineffective at reducing emissions.Despite these challenges, Microsoft remains committed to achieving carbon negativity by 2030.

This trend aligns with broader industry concerns as tech giants like Amazon and Google report similar emission increases, highlighting the environmental costs of expanding data center networks.
