Their test cases were 600 ppm, 1000 ppm, and 2500 ppm of CO2, and they found measurable differences in human performance between those.
I am curious what would happen if they dropped the CO2 concentration down to something that's less than what they see in an urban environment? Does dropping to 300 ppm or 0 ppm have any measurable benefit? Are there any downsides to breathing air with no CO2?
