Microsoft is expanding its use of "biomimicry" at data centers to counteract growing local opposition regarding construction, pollution, and noise.
San Antonio City Councilmember Ric Galvan recalls the early days when data centers looked like unassuming office buildings. However, recent years have seen the facilities grow into massive "hyperscale" centers housing the physical infrastructure for AI.
There are now more than a dozen data centers in Galvan's district, a number he expects to rise to around 20 if proposed projects are completed. These facilities cluster along main roads, concentrating nuisances such as construction traffic, deforestation, and the constant bright lights and noise of operation.
Residents across the US are rising up against these facilities, protesting impacts on quality of life and resources. While tech companies have promised to fund local infrastructure upgrades, Microsoft is pursuing a different approach to soften its impact.
The company announced plans to make its data centers less disruptive through "biomimicry," a concept involving technologies inspired by nature, such as naturally ventilated buildings modeled after termite mounds.
In Microsoft's case, this involves blending data centers into the natural landscape to create resilient ecosystems that support biodiversity and strengthen community ties.
Essentially, Microsoft aims to make its data centers greener by incorporating more gardens and native trees on-site, while investing in projects to repair damaged ecosystems.
Advocates and sustainability experts view this as a positive step, though they note that data centers continue to expand rapidly. Microsoft has razed thousands of trees to build new facilities, and its greenhouse gas emissions are rising with AI energy demands.
Galvan expressed frustration over the company's 2022 decision to cut down more than 2,600 trees for a San Antonio site. "We’re very proud of our trees here," he said, noting the canopy's role in mitigating heat. Microsoft has since promised to invest in enhancement projects, including the restoration of over 400 acres of woodland and pollinator prairie.
Microsoft has experimented with nature-inspired solutions in the Netherlands and plans to bring them to over 20 sites in the US and Germany, customizing solutions to fit local habitats.
One example is in Wisconsin, where Microsoft restored a creek and installed stormwater management systems at a former Foxconn factory site. "Not all data center companies are the same," said Dave Giordano of the Root-Pike Watershed Initiative Network.
Microsoft has also improved community relations by hiring local representatives and launching a plan to manage energy and water demands.
However, critics like Adrian Shelley argue that these nature-based solutions are insufficient. "I have nothing bad to say about nature-based solutions that are sensitive to the native ecosystem," Shelley said. "However, I think that it’s, you know, basically lipstick on a pig." Shelley is particularly critical of the gas plants Microsoft is using to power new data centers, stating, "I cannot really see any level of biomimicry investment that makes a gas plant a desirable neighbor."
In response to these concerns, officials in San Antonio have proposed a moratorium on new data center development, and Texas Governor Greg Abbott has also paused permits pending audits.
Erin Kinney, a researcher at HARC, acknowledged the potential for local benefits but emphasized the need for accurate tracking and community alignment.
Despite goals to become water positive and carbon negative by 2030, Microsoft's sustainability report showed a 25% increase in carbon pollution in 2025 due to AI demands. Former executive Holly Alpine argued that AI is enabling more pollution than the company addresses with localized projects.
Microsoft officials maintain that delivering AI infrastructure requires diverse energy solutions in the near term, though they continue to invest in decarbonization technologies.
