Tech giants lock in gas plants to power AI data centers

Amazon, Microsoft, Google, and Meta are constructing new, supersized gas-fired power plants to fuel their expanding data center networks. According to corporate disclosures and an analysis by a researcher at the Harvard T.H. Chan School of Public Health, these projects threaten to lock in hundreds of millions of tons of climate pollution for decades. The industry estimates place the tech sector on a trajectory to grow from a modest contributor of industrial carbon into one of the world's largest emitters of greenhouse gases by 2030.

The shift contrasts with earlier corporate pledges. In 2019, Amazon founder Jeff Bezos stated that the company would eliminate planet-warming emissions ten years ahead of the Paris agreement timeline. Other tech leaders subsequently vowed to move even more aggressively toward net-zero targets. However, recent corporate filings indicate that the push to expand artificial intelligence and cloud computing has driven emissions sharply higher.

Gianluca Guidi, the Harvard researcher who conducted the analysis, noted that AI infrastructure is physical. It requires land, power plants, transmission lines, water, and fuel. His review of air permits and community presentations shows that the physical choices made now can persist for generations. Industry data suggests the tech sector's share of global carbon emissions could increase fivefold between 2020 and 2030. That level of output would exceed the climate pollution created by global aviation or shipping sectors.

Amazon’s carbon footprint reached 80.85 million metric tons last year. That figure is 58 percent larger than when Bezos made his initial pledge. The company’s trajectory has veered away from the Paris agreement path, which called for steep declines in emissions by 2030. Two gas projects recently signed by Amazon to power data centers in Texas and Pennsylvania would produce more carbon pollution than the James H. Miller Jr. coal plant in Alabama. That coal facility is the dirtiest in the United States and powers one million homes.

Meta is building a campus in rural Louisiana that covers nearly six square miles. The site will consume as much electricity as three cities the size of New Orleans. The gas plants powering that operation would create more carbon emissions than the entire Meta corporation currently generates. In West Texas, a Microsoft project involves a giant gas plant built by Chevron. A separate Google project in Wyoming is designed to consume five times as much electricity as all households in that state combined.

Tech companies maintain they remain committed to net-zero targets. They argue the current emissions surge is temporary and will be mitigated by new energy technologies. Amazon spokeswoman Margaret Callahan said a recent Texas gas plant deal is one piece of a larger picture that includes the world's largest portfolio of carbon-free energy. She noted Amazon has invested billions of dollars in more than 712 carbon-free energy projects totaling 42 gigawatts worldwide. The company is working toward net-zero carbon emissions by 2040.

Climate experts warn that these investments reduce pollution on paper but do not change the physical reality of adding new gas plants. Thomas Day, director of corporate accountability at the New Climate Institute, described the situation as a disaster from a climate perspective. He said the companies are locking in huge fossil fuel projects that will become among the world's biggest emitters. Allianz, an international insurance giant, calculated that absent a pivot to cleaner energy, the tech sector's emissions could create about $164 billion in annual climate damages.
