The emissions from powering data centers rightly get a lot of attention. But new research from former Microsoft sustainability workers cautions that the way artificial intelligence enhances productivity in the oil and gas industry could be much more damaging to the planet.

Published last week in the journal npj Climate Action, the research finds that AI use could significantly increase global energy emissions simply by enabling the fossil fuel industry to produce more oil and gas. At the low end, the research finds that the additional yearly emissions could be equal to Mexico’s; at the high end, AI boosting the fossil fuel industry could add as much greenhouse gas emissions as Russia, the world’s fourth-largest emitter.

That increase in emissions, the paper finds, outweighs the benefits AI provides to developing solar, wind, and other clean technologies. It also significantly outpaces projections of emissions from the global data center buildout.

The relationship between technology companies and fossil fuels is “a self-reinforcing effect between supply and demand,” says Will Alpine, one of the authors of the research. “One of the key insights of our paper is that you cannot treat them independently. They are two sides of the same coin.”
