AI's Arrival Complicates Big Tech Climate Goals, and Some Worry it's Locking in More Fossil Fuels

March 28, 2026 (AP) – Six years ago, Google was confident that by 2030 it would power all operations with electricity generated from clean sources, including wind and solar power, and remove as much pollution as it produced. Today it calls those goals a “moonshot.” Microsoft says it's still aiming to remove more carbon than it creates by 2030 but now describes the effort as “a marathon, not a sprint.”

The race to deploy artificial intelligence is complicating tech companies' commitments to reduce greenhouse gas emissions, most of which come from the burning of gas, oil and coal and drive climate change. They say they must be flexible as they rush to build sprawling data centers that can consume more power than entire cities.

“Even if they haven’t officially revised their goals, they are starting to acknowledge that, ‘Yeah, we’re maybe not on track,’” said Patrick Huang, a senior analyst at Wood Mackenzie.
