US moves to loosen data center pollution oversight as Australia tightens it
The EPA wants to drop the requirement that neighbors be told before new data centers get air pollution permits, even as public anger over bills and pollution grows.
What happened: The EPA has proposed scrapping a federal rule that requires public notice and comment before certain industrial sites, including data centers, get air pollution permits. The change would push that decision to individual states, many of which advocates fear will skip public input altogether. Meanwhile, nearly 200 health and environmental groups have asked the EPA to withdraw the plan, and the agency is still working through more than 4,900 public comments before finalizing anything.
Why it matters: Data centers have become one of the most contested pieces of infrastructure in America. Roughly seven in ten Americans oppose new data centers near them, citing pollution, water use, and rising electric bills. US utility prices climbed 4% in the year to June, outpacing inflation, and residents increasingly blame the power-hungry buildings feeding the AI boom. Removing public comment removes one of the few tools communities have to flag problems before construction starts.
How it works, plainly: The permitting process at stake, New Source Review, has required public notice since the 1970s for facilities the EPA calls 'minor' polluters. Critics say that label undersells the real impact, pointing to xAI's Tennessee data center, which drew thousands of public comments and a lawsuit threat over unpermitted gas turbines. If the EPA finalizes its change, states would decide case by case whether to tell residents anything before bulldozers arrive.
The rollout: Contrast that with Australia, where national cabinet just agreed that new data centers must run on 100% renewable energy backed by storage, with only narrow exemptions if a state-owned utility can prove fossil fuels are cheaper. That national standard is expected to reach parliament next year. In the US, the Trump administration's voluntary 'Ratepayer Protection Pledge' asks companies to cover grid costs themselves, but critics call it toothless since it carries no legal penalties for breaking it.
