A recent analysis found that 51 diesel generators and eight natural gas turbines at a Vantage facility in Loudoun County, hosting Amazon servers, emit fine particulate matter (PM2.5) that could cause 3.4–6.5 premature deaths per year, rising to nearly 200 fatalities over 30 years. The report also estimates nearly $100 billion in annual health-related damages tied to increased respiratory and cardiovascular ailments among local residents.

The projected mortality and financial costs may trigger stricter emissions limits or require additional pollution controls at data centers, potentially increasing operational expenses for Amazon Web Services in Loudoun County. Long-term reputational risks and community opposition could slow future capacity expansions in one of AWS’s major data center hubs.
