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

Living tracker: refreshed mid-October 2026, with dated entries through October 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 BloombergNEF's most recent count, as of late September, stood at 74 gigawatts of announced on-site gas power capacity at U.S. data centers, which BNEF's Mark Daly says would serve about 48 gigawatts of facility load after accounting for equipment redundancy; it is a different measure from the firm's August census of proposed plants. 5 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. 6 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. 6 Amazon spokesperson Margaret Callahan told the New York Times that "the world looks different now than when we co-founded the climate pledge." 6 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 The build-out may not stop at Pecos County: on September 18, Texas Public Radio reported that Pacifico Energy, the plant's developer, had met days earlier with officials in neighboring Brewster County about a second off-grid gas plant and data center campus on an 8,400-acre ranch in the Glass Mountains, a project company representatives described as in its feasibility phase, with one to two years of planning before construction could begin. 7 The same report notes the Pecos facility holds the largest air pollution permit issued in the country, and that three Democratic senators told Pacifico in a March letter the plant will emit 33 million tons per year of climate-warming greenhouse gases and 12,000 tons per year of health-harming pollutants including soot, ammonia, and carbon monoxide. 7

- Meta: Net-zero by 2030, 4 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. 8

- 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. 9 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 The friction has reached its existing fleet too: a Microsoft-backed data center in Vineland, New Jersey, was recently fined $1 million for running dozens of gas-powered generators without the proper permits, and ordered to obtain them within 45 days or shut down. 5

- xAI, now SpaceXAI: No public net-zero pledge. SpaceX acquired xAI earlier in 2026 and folded it into an AI arm named SpaceXAI. 10 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 6 The fleet keeps growing: Mississippi regulators counted 69 temporary turbines at the Southaven site by July, more than double the number the company had publicly acknowledged at the start of the year, with a capacity of roughly 1,775 megawatts, and on July 30 the state signed an agreement with the site's owner, SpaceX subsidiary MZX Tech, letting 13 of them keep running through the end of the year while permanent turbines come online. 10

- 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. 11 That pipeline hit its first hard wall in late September, when New Mexico regulators blocked a gas pipeline proposed to serve Project Jupiter, the 2.5-gigawatt Stargate campus in Doña Ana County, and Oracle moved to protect itself financially from the project's delay or cancellation. 5 OpenAI's appetite keeps growing anyway: in September the company agreed to take 8 gigawatts of capacity from a planned 10-gigawatt generation project in Ohio that includes 9.2 gigawatts of gas assets, being pursued by Japan's SoftBank Group and the U.S. Department of Energy, a facility Utility Dive reports would be the country's largest generation source if built, a title that would otherwise fall to Amazon's proposed Texas gas plant. 5

Meta and Microsoft, with 4 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. 6 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. 8 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 12 Microsoft's own report landed July 9 with its 25% year-over-year jump. 9 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. 13 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. 11 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. 14 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 On September 9, Scientific American reported that the temporary turbine fleet at Southaven, the Mississippi site powering SpaceXAI's Colossus 2 campus (SpaceX acquired xAI earlier in the year and folded it into an AI arm of that name), had grown from 46 machines in May to 60 in June to 69 by July, and that the Department of Justice had moved in June to intervene on the company's side, asking the court to dismiss the NAACP's lawsuit over the turbines. 10 On September 18, Texas Public Radio, citing a Texas Tribune investigation, reported 335 existing data centers across Texas and another 248 in development, nearly half of them planned for unincorporated areas outside cities. 7 On September 21, Governor Greg Abbott directed the Texas Commission on Environmental Quality to halt all permits sought by data centers until the Electric Reliability Council of Texas completes an audit of its interconnection waitlist, with a compliance report due to the governor's office by October 19. 15 The order capped a seven-week escalation: an August 3 directive ordering the Public Utility Commission and ERCOT to audit every data center in the interconnection queue, which then held more than 474 gigawatts of requests, roughly five times the grid's all-time peak demand and about 90 percent of it attributable to data centers; a September 14 directive ordering the Texas Water Development Board to enforce water-use reporting, under which a project that fails to return its survey commits a criminal offense and becomes ineligible for TCEQ permits; and a pledge to work with the Legislature, which convenes in January, to eliminate the industry's financial incentives. The freeze covers permits, amendments, and renewals regardless of whether a project sits in the ERCOT queue, so it reaches behind-the-meter projects that never needed grid approval, and ERCOT now expects to complete its audit in mid-December. 16

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. 8 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, 13 and in Texas, Governor Greg Abbott's August moratorium on new data center grid connections escalated on September 21 into a directive ordering the state's environmental regulator to halt all data center permits pending an ERCOT audit; analysts at BloombergNEF estimate the pause puts almost 20 percent of the country's 253-gigawatt data center pipeline, nearly 50 gigawatts of proposed capacity, at risk. 15 17 The opposition is no longer only Texan: a Heatmap News poll fielded in May found 71 percent of Americans would oppose a data center being built nearby, up nearly 30 percentage points from September, and Heatmap counted at least 20 proposed data center projects killed by local opposition in the first quarter of 2026, the most of any quarter on record. 5 Goldman Sachs, for its part, said in May that only 50 to 60 percent of planned data center capacity will actually come online in the next two years amid delays and cancellations. 5

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
