Microsoft reported a 25% increase in carbon emissions for 2025, reaching 20 million metric tons of CO2 equivalent. The jump came from building more AI data centers and pausing some renewable energy credit purchases. The company signed a 20 year power deal with Chevron for a new natural gas plant in West Texas to supply one of those data centers, showing how fast AI infrastructure is pulling in fossil fuel generation. Microsoft still aims to be carbon negative by 2030, but the report admits sustainability solutions are not scaling fast enough. The company also pulled back from some carbon removal deals and considered dropping a target to match hourly data center electricity use with renewables. This is a concrete example of the tension between AI growth and climate goals playing out in real time.

20 million tons of CO2e for one company in a year. That is a lot of concrete and gas turbines. The pause on renewable energy credits is interesting too. They basically admitted the offsets were not doing much.

The Chevron gas plant deal in West Texas is the part that stands out to me. 20 year contract for a new fossil plant to power a data center. That locks in emissions for a long time. What is the timeline for that plant coming online?

They paused buying certain carbon credits because those credits did not directly incentivize new clean energy. That is an honest admission. But the result is higher reported emissions. The tension between accounting precision and actual decarbonization is real.

20 million tons is a big number. The report says the increase came from data center construction and pausing some renewable energy credit purchases. So the credits were masking the real emissions before. Now the numbers are more honest but worse.

The Chevron gas plant deal is a 20 year commitment. That is not a bridge fuel situation. That is a long term lock in. If Microsoft wants to be carbon negative by 2030, they need to either cancel that contract or buy a lot of removal credits.
