Who bears the burden of data center pollution?
Low-income and rural communities are most vulnerable to the negative impacts of data center emissions and resource use. A global study on human-wildlife conflict found that economic vulnerability to environmental costs is two to eight times higher for households in developing economies compared to developed ones, and losing a single cow can equate to nearly a year and a half of lost calories for a child [2]. While this study focuses on wildlife, the same principle applies to data center pollution: poorer communities have fewer resources to adapt to or mitigate environmental harms. Another study on air pollution risk information in China found that rural residents are less likely to receive and act on pollution warnings than urban residents, leading to greater health losses from the same level of pollution [1]. This means that if a data center increases local air pollution, nearby rural communities may suffer more health damage because they lack the information or means to protect themselves.
How do data centers specifically worsen inequality?
Data centers create inequality through three main channels: air pollution, water consumption, and policy favoritism. A 2025 case study of data centers in Arizona found that these facilities can consume up to 5 million gallons of water daily, while local residents face severe water shortages [3]. The same case study notes that data centers often receive tax credits and discounted utility rates, while local communities bear the costs of strained water supplies and increased pollution. A 2022 global analysis estimated that if not properly managed, annual carbon emissions from storing 'dark data' (unused data) could reach 5.26 million tons, with water footprints of 41.65 gigaliters and land use of 59.45 square kilometers [4]. These environmental costs are not evenly distributed: data centers are often sited in lower-income areas where land is cheaper and regulations are weaker, concentrating pollution and resource depletion in communities that already face multiple environmental burdens.
What can be done to reduce these inequalities?
Policy interventions can mitigate the unequal impacts of data centers. A 2025 policy analysis recommends that states with data center tax breaks should require energy audits, strict performance standards, and renewable energy integration, and should ensure that data centers contribute to new renewable capacity rather than using existing resources [5]. The same analysis suggests that if these measures fail, states should consider repealing tax breaks to slow unsustainable growth. For states without tax breaks, the recommendation is to avoid offering them and instead implement mandatory reporting requirements to hold data centers accountable for their environmental impact [5]. Additionally, changing air quality standards to more stringent levels (e.g., adopting the American standard in China) could reduce PM2.5-related premature deaths by 9.9%, according to one study [1]. This shows that stronger regulations can reduce health inequalities, but only if they are enforced equitably across all communities.

Health benefits from risk information of air pollution in China
This study found that air pollution risk information is unevenly distributed across regions and populations in China, leading to unequal health gains; rural residents, men, and younger people are less likely to receive and act on such information, resulting in higher health losses from the same pollution levels.
The unequal burden of human-wildlife conflict
This global study of 18 large carnivores found that economic vulnerability to livestock losses is two to eight times higher for households in developing economies compared to developed ones, and losing a single cow can equate to nearly a year and a half of lost calories for a child.
Environmental Impact of Data Centers
This 2025 case study of data centers in Arizona found that these facilities can consume up to 5 million gallons of water daily, while local residents face water shortages, and data centers often receive tax breaks and discounted utility rates at the expense of local communities.

What Happens When Data Centers Come to Town?
This 2025 policy analysis recommends that states with data center tax breaks should require energy audits, renewable energy integration, and 'additionality' clauses to ensure new renewable capacity, and suggests repealing tax breaks if these measures fail.
