Meta exits RE100 pact as natural gas buildout reaches 7.5 GW
Meta's departure from the RE100 clean energy initiative after a decade marks the clearest indication yet that AI's surging power demand is forcing Big Tech to reconcile climate pledges with energy reality.
Meta exited the RE100 clean energy pact after 10 years of membership while funding at least a dozen natural gas power plants totaling 7.5 GW — enough electricity to power the entire state of South Dakota, according to TechCrunch.
"Meta remains committed to matching its data center electricity usage with 100% clean and renewable energy," a Meta spokesperson said, without addressing the contradiction between the gas buildout and the RE100 departure.
The company's first gas plant was a 200-MW behind-the-meter facility in Ohio announced in June 2024. Two months later, Meta said it would build three large gas plants in Louisiana for its Hyperion data center, then added seven more in April. The 10 Hyperion plants will generate 7.5 GW. A single 1-GW data center running on natural gas releases 438 metric tons of nitrogen oxides and 149 metric tons of fine particulate matter annually, contributing to asthma, cardiovascular disease and other health conditions.
The pivot threatens Meta's standing with ESG-focused investors who collectively manage trillions in assets. Competitors Apple, Google and Microsoft remain in RE100, with Microsoft pursuing hourly renewable matching and Google pairing renewables with battery storage in Minnesota — creating a competitive divergence in how hyperscalers power their AI infrastructure.
The Accounting Loophole Behind "100% Renewable"
Meta can still claim 100% renewable energy by purchasing environmental attribute certificates — effectively buying a solar farm's output in Arizona to offset a gas-powered data center in Ohio. As long as the solar farm generates enough energy in one year to match the data center's annual consumption, Meta counts that as 100% renewable. Most tech companies use this annual matching approach, but Microsoft has moved to hourly matching, a more rigorous standard that encourages battery-backed renewables rather than fossil fuel backup. The approach aligns power production more closely with how data centers actually consume electricity.
RE100, a project of the Climate Group — a UK-based nonprofit co-founded by former Prime Minister Tony Blair — recently updated its guidance to enforce more rigorous reporting on progress toward renewable energy goals. Meta had previously told the group it would "run its entire operations on renewable electricity by 2020," a target it missed. The breakup was mutual, according to a Meta spokesperson, though the company declined to comment on specific reasons for the departure. The global market for renewable energy certificates has grown to billions of dollars annually, with tech companies among the largest buyers. Critics argue the system allows companies to claim environmental progress without reducing actual fossil fuel consumption, a concern that grows more acute as AI data center power demands escalate.
What It Means for AI's Carbon Footprint
The 7.5 GW from Meta's Louisiana gas plants exceeds the total electricity consumption of some US states. As AI workloads grow, the industry faces a choice between the low latency of dedicated gas power and the intermittency challenges of renewables. Google and Microsoft have also invested in large fossil fuel projects, but Meta's bet is the largest — and its RE100 exit makes the trade-off explicit.
Meta shares, trading at about 23 times forward earnings, face potential downgrades from ESG rating agencies if the gas buildout continues without equivalent renewable procurement. The RE100 exit also invites regulatory scrutiny and shareholder activism, particularly in Europe where the Climate Group's initiative carries more weight with institutional investors. For the broader data center industry, Meta's move sets a precedent that could weaken voluntary climate commitments across the sector, as hyperscalers collectively account for a growing share of global electricity demand.
The divergence among Big Tech's energy strategies creates a clear winner and loser in the ESG investment community. Microsoft's hourly matching approach and Google's battery-backed solar projects position them as leaders in sustainable AI infrastructure, while Meta's gas-heavy strategy risks alienating a growing pool of climate-conscious capital. With global data center electricity consumption projected to double by 2030, the stakes for getting the energy mix right have never been higher.
