Of course. Esp. for the bigger datacenters which generate their own power and release large amounts of emissions to the atmosphere.

It's good that that air never moves and all this emission stays inside the cube formed by the ground, four borders of the datacenter and personal airspace ceiling prescribed by the governments.

Given that the datacenter operators run air purifiers and give the filtered out emissions to government (or licensed 3rd parties) for conversion to carbon credits, there's no harm done.

Just some local noise nuisance, and maybe some heat, but all of them are manageable. Residents can use earplugs and more powerful air conditioners to restore or surpass their previous life quality.

This is not only progress, but how one changes the world for the better.
