Can a measured CO2 concentration show a building is SARS-CoV-2 safe?

An indoor CO2 concentration is commonly used as an indicator of the ventilation rate in indoor spaces, albeit with great uncertainty. Its concentration depends on the number, demographics, and activities of occupants, the outdoor air supply rate, mixing, inter-zonal airflow, the air renewal rate, and the outdoor concentration.
