EPA Moves to Strip Public Review Rights for Data Centre Pollution Permits
Bisnow · 27 August 2026
TL;DR
The US Environmental Protection Agency, under the Trump administration, has proposed eliminating a Clean Air Act requirement that forces states to publicly disclose air pollution permit applications from data centres and other facilities emitting up to 250 tons of pollutants annually. The change would remove mandatory public comment periods at the federal level, handing those decisions entirely to individual states. Critics — including 14 state governments and hundreds of advocacy groups — argue the move undermines transparency. The EPA frames it as streamlining permitting to support economic development and AI infrastructure growth. Meanwhile, a Bisnow investigation found that emissions from major tech and data centre firms rose sharply year-on-year, with six hyperscalers alone releasing 171 million tons of carbon in their most recently reported year.
Our take
While this story originates in the United States, it carries real relevance for South African property professionals, investors, and municipalities watching the global data centre boom land on local soil. South Africa — particularly Johannesburg, Cape Town, and increasingly smaller metros — is actively courting hyperscale data centre investment. The regulatory environment here is shaped by different instruments (the National Environmental Management Act, the Air Quality Act, and municipal by-laws), but the underlying tension is identical: communities want a say in what gets built near them, and developers want faster approvals. For SA landlords and commercial property developers, the US experience signals that data centre tenants bring not just premium rental income but genuine community relations risk. Backup diesel generators — standard in any SA facility given our load-shedding reality — are precisely the emission source at the centre of this US debate. Local developers should proactively engage with air quality permit processes rather than treat them as a box-ticking exercise. For municipal planners and environmental practitioners, this story is a cautionary tale: if public participation rights are eroded at the federal level elsewhere, pressure may mount locally to fast-track approvals similarly. Protecting robust public comment periods under SA's existing frameworks is worth defending now, before the political pressure intensifies.
