Data Centers Are Dealing Hidden Damage to Environmental and Public Health—Costing the Economy $25 Billion Every Year

Why It Matters

The findings expose a massive, often overlooked external cost that challenges the economic justification for aggressive data‑center expansion and prompts policymakers to rethink incentives and environmental safeguards.

Key Takeaways

• Data centers generated $25 B in annual health and climate damages.
• AI‑related workloads account for $3.7 B of those costs.
• Virginia and Texas together bear ~30% of health‑damage costs.
• Tax incentives cost states over $100 M each year, eroding revenues.
• Externalities could rise 85% if AI demand continues expanding.

Pulse Analysis

The data‑center boom, fueled by a $47 billion investment surge and $182 billion in corporate borrowing, has reshaped the U.S. electricity landscape. Researchers at Carnegie Mellon measured the resulting emissions and linked them to premature mortality, translating the health toll into a $25 billion economic externality. AI‑intensive workloads, while driving the surge, contribute $3.7 billion of that figure, highlighting that the most visible impact of these facilities is not revenue but public‑health degradation.

Local governments have courted data‑center developers with generous tax abatements, hoping to capture new property and equipment taxes. However, the PwC study shows that while total government receipts rose to $162.7 billion in 2023, at least ten states now lose more than $100 million annually because of undisclosed incentives. The promised permanent employment boost has proved fleeting, and utility rate hikes—some exceeding 250% in hotspot neighborhoods—have turned data centers into political flashpoints. Residents in Virginia’s “data‑center alley” and Texas’ growing clusters bear disproportionate health costs, accounting for roughly a third of the national total.

Policymakers face a dilemma: balance AI‑driven productivity gains against escalating environmental externalities. If AI lifts GDP even modestly, the external cost could remain a small share of new output, but current projections suggest an 85% rise in damages as demand accelerates. Mitigation strategies—such as mandating renewable power, tightening emissions standards, and redesigning incentive structures—could curb the health burden while preserving the sector’s economic contributions. The debate now centers on whether the long‑term benefits of AI justify the immediate public‑health costs, and how regulation can align private incentives with societal well‑being.
