NEWARK, September 24 — New Jersey environmental regulators have hit a Newark data center that supplies computing power for Microsoft’s Copilot artificial intelligence service with a $1.1 million penalty, the largest fine the state agency has ever levied against a single data center facility for air pollution violations. The New Jersey Department of Environmental Protection announced the penalty on Tuesday.
It stems from repeated exceedances of nitrogen oxide emission limits from the facility’s backup diesel generators during testing and maintenance over a period spanning more than two years, according to the agency.
The violations
NJDEP officials said the operators failed to properly monitor and report emissions and did not install required pollution control equipment on time. The $1.1 million figure includes a $750,000 civil penalty and $350,000 for a supplemental environmental project to fund local air quality monitoring in overburdened communities near the site. The data center is operated by a subsidiary of a major technology company and supplies cloud computing capacity used to run Microsoft Copilot, the AI assistant integrated into Microsoft 365 products.
It sits in an area that qualifies as an overburdened community under New Jersey’s Environmental Justice Law, signed in 2020, which requires additional scrutiny for facilities in minority and low-income communities. New Jersey maintains some of the strictest air pollution regulations in the country, particularly for diesel generators, which are a significant source of nitrogen oxides and particulate matter.
Industry and environmental reaction
Microsoft declined to comment on the specific penalty but said it is committed to environmental sustainability and is working with its suppliers to ensure compliance. The data center operator did not respond to requests for comment. Environmental groups praised the NJDEP’s action, calling it a precedent-setting enforcement that holds tech companies accountable for their supply chains.
The New Jersey Business and Industry Association expressed concern that the fine could discourage data center investment in the state. The penalty was issued on Tuesday, and the data center has 30 days to appeal.
The NJDEP has stated it will continue to aggressively enforce air quality regulations. The fine lands amid growing national scrutiny of the environmental impact of data centers, which consume massive amounts of electricity and often rely on diesel generators for backup power. As AI services like Copilot expand, demand for data center capacity has surged, leading to increased emissions and water usage.
Strategically, the calculus here extends beyond a single Newark facility. New Jersey has now demonstrated it will pursue enforcement through the supply chain, reaching a tech giant’s cloud capacity by way of a subsidiary operator’s generators.
Whether other states follow that template — and whether the appeal holds — is the next marker to watch.
