I can't sleep if the temperature is a few degrees warmer than normal. Imagine training for 4+ years and then not sleeping before the biggest event of your life, because of poor planning. Consistency is key for these atheletes.

If emissions were a big enough issue for the hosts, then they shouldn't be flying tens of thousands of tourists & atheletes to come watch some sports. AC units are a drop in the bucket.

Yup. And ironically, the buildings are designed for one set of guests — the Olympic athletes — and if they had done their planning keeping the athlete's requirements as the primary criteria, they would have ended up with a far more climate-effective solution.

Instead, they have a cooling system that starts out as known-insufficient, and will definitely be unable to meet requirements in case of even normal heat waves, nevermind the what-used-to-be-outlier events that are now far more common. And, because of that planned inadequacy, hundreds or thousands of new temporary AC units will be built, transported, installed, and run at vast otherwise-unnecessary expense and emissions.

Building the initial system to meet requirements under any conditions found in the last two decades, and using modern AC technology that allows motors to run at variable speeds (vs compressor ON/OFF only) would be vastly more energy-efficient, and actually more climate-friendly.
