The AI Climate Pledge Gap: We Tracked Every Major AI Company Building Gas Plants While Promising Net Zero

Living tracker: refreshed September 2026, with dated entries through August 19, 2026. Every figure carries its source.

Gas plants planned to serve AI data centers across the United States carry a combined permitted capacity of 660 million tons of CO2 per year, roughly matching Australia's national emissions. 1 Four of the biggest names building them, Google, Amazon, Microsoft, and Meta, have all set net-zero goals. 1 Neither xAI nor OpenAI has a public net-zero pledge. 2

The numbers keep climbing. Research firm Cleanview has identified around 60 planned data centers with a combined 97 gigawatts of behind-the-meter gas generation, comparable to Mexico's entire installed power capacity, running into the early 2030s. Even under conservative assumptions about utilization, those projects would emit over 200 million tons of CO2 annually. 3 A Bloomberg News analysis published August 19 counts even more: 99 proposed on-site gas plants tracked by the research firm BloombergNEF, spread across 22 states, totaling 126 gigawatts. Run at industry-standard utilization rates of about 60 percent, Bloomberg estimates they would emit about 318 million metric tons a year, a 20 percent lift on the roughly 1,485 million tons the US power sector emitted in 2025. 4 A WIRED review of air permit documents for 11 data center campuses linked to OpenAI, Meta, Microsoft, and xAI found 129 million tons of potential annual emissions, roughly equivalent to Morocco's 2024 national output. 2 Amazon's 7.65-gigawatt gas plant in Pecos County, Texas, permitted for 33 million tons per year, was confirmed months after that count and sits outside it. 5 Construction permits followed in August, with satellite imagery confirming site clearing underway. 3

The Pledge Gap, Company by Company

Cross-referencing each company's public net-zero commitment against the CO2 permitted from their identified gas projects produces a structural contradiction. The companies with the least time to their deadlines are adding the most fossil fuel capacity.

- Amazon: Net-zero carbon by 2040. Emissions rose 16% year-over-year in its latest sustainability report. 1 Its Texas gas plant uses 35 turbines generating up to 7.65 gigawatts and is permitted for 33 million tons of CO2 annually. Amazon is also in talks for a 4.5-gigawatt plant in Homer City, Pennsylvania. 5 Amazon spokesperson Margaret Callahan told the New York Times that "the world looks different now than when we co-founded the climate pledge." 5 Bloomberg reported in August that Cleanview had identified Amazon as the developer of the 8,000-acre Pecos County site, and that it and a Chevron-built plant for Microsoft about 30 miles west could together emit as much as 45 million metric tons a year, according to regulatory filings. Amazon says it is exploring solar and battery storage at the Texas site, and spokespeople for Amazon and Microsoft say their climate goals have not changed. 4

- Meta: Net-zero by 2030, four years out. Emissions jumped 64% year-over-year. 1 Williams Companies, an oil and gas company, is building three behind-the-meter gas plants in Ohio for Meta. 2 Meta is separately investing $1.6 billion in a 400-megawatt gas plant in New Albany, Ohio. 6

- Microsoft: Pledged carbon-negative by 2030. Emissions sit 23% above a 2020 baseline in its 2025 sustainability report. 1 Its 2026 report, published July 9, showed total emissions across Scopes 1, 2, and 3 up 25% year over year, an increase the company attributed primarily to the expansion of its datacenter infrastructure. 7 A Chevron-backed gas project in West Texas that Microsoft was reportedly exploring in April would be permitted for 11.5 million tons per year. 2 By August, Bloomberg reported Chevron was building the plant for Microsoft on a 2,000-acre site. 4

- xAI: No public net-zero pledge. Gas turbines at its Colossus campuses in Memphis, Tennessee and Southaven, Mississippi are each permitted for over 6.4 million tons of CO2 equivalent annually, with the two sites combined roughly matching the output of more than 30 average natural gas plants. The NAACP has sued xAI, accusing it of unlawfully operating turbines without proper air permits. 2 5

- OpenAI: No public net-zero pledge. Three Stargate-affiliated gas projects in Texas and New Mexico carry a combined permitted potential exceeding 24 million tons per year. 2 At Stargate's flagship Abilene, Texas campus, developers have already built 10 gas turbines and 62 backup diesel generators, and want to add 41 more turbines and 18 more generators. 8

Meta and Microsoft, with four years remaining before their 2030 commitments, are locking in gas infrastructure that will operate well past those deadlines. Amazon, with 14 years of runway, is building what the New York Times described as potentially the single largest source of climate pollution in the United States. 5 Google has stopped speaking in terms of concrete 2030 goals and instead frames its emissions ambitions as "climate moonshots," a term the company uses to denote speculative projects that may or may not materialize. 1

From One Memphis Site to 97 Gigawatts

The behind-the-meter gas boom began in 2024, when xAI trucked mobile gas turbines into Memphis to power its Colossus data center. xAI still accounts for most of the approximately 2 gigawatts of behind-the-meter generation currently online. 3 By March 2026, Senate Democrats Sheldon Whitehouse, Martin Heinrich, and Chris Van Hollen had launched an investigation into nine companies over 12 planned gas projects, asking why they did not opt for cleaner sources; the same month, state environmental regulators approved 41 additional turbines for xAI's Memphis campus despite complaints that the site was flouting air pollution limits. 6 By April, WIRED documented 129 million tons from 11 campuses. 2 By July, the Environmental Integrity Project counted 660 million tons across 74 plants and 143 gigawatts, while all four major hyperscalers disclosed rising emissions in their annual sustainability reports. 1 9 Microsoft's own report landed July 9 with its 25% year-over-year jump. 7 Days earlier, President Trump said his administration was now approving private power plants for data centers "in a matter of weeks," adding that he had personally called Mark Zuckerberg, Jeff Bezos, Sam Altman, and Elon Musk to ask why they had not submitted plans. 10 A Floodlight investigation published with the Texas Tribune found at least 15 gas plants tied to data centers planned in Texas alone, with permits for nine of them combining to more than 130 million tons a year, which the EPA's own calculator equates to 35 coal-fired power plants. 8 By August 5, the New York Times, drawing on the Environmental Integrity Project's updated tally, counted at least 82 gas-burning plants being built or proposed for data centers nationwide, 39 of them in Texas. 11 Six days later, Cleanview's full pipeline stood at 97 gigawatts across roughly 60 data centers. 3 On August 19, Bloomberg's count of the same build-out reached 99 proposed plants and 126 gigawatts, with more than a third of the projects in Texas. 4

In 2025, 252 gigawatts of gas-fired power entered development in the United States, nearly triple the prior year, according to Global Energy Monitor, with one-third slated for on-site use at data centers. 6 Development tilts toward Republican-leaning states, with Texas alone at more than 40 gigawatts announced. 3 The backlash is growing alongside the build-out: New York's legislature passed a one-year moratorium on data center permits in June, pending the governor's signature, 10 and Texas Governor Greg Abbott has announced a pause on new data center approvals. 4

These figures are drawn from state air permit filings and from databases maintained by Cleanview and the Environmental Integrity Project's Oil and Gas Watch. 2 Permitted emissions represent a theoretical maximum, assuming turbines run at full capacity around the clock. Energy researcher Jon Koomey estimates grid-connected gas plants typically emit 40 to 50% of their permitted levels, but data center turbines run closer to their full output because they do not respond to fluctuating grid demand. 2 Bloomberg's August analysis lands in the same range from the other side: assuming an industry-average 60 percent utilization rate yields about 318 million tons a year, while plants run flat out could add as much as a third to US power sector emissions. 4 Williams Companies told WIRED that internal modeling shows actual emissions from its Ohio plants for Meta could be "potentially two-thirds less than what's on paper." 2 Even at half of permitted levels across all identified projects, the combined output would still exceed Norway's annual national emissions. 2
