In March 2022, ASHRAE released a position document discussing the role of indoor CO₂ in the context of building ventilation and IAQ. The positions address the use of CO₂ as a metric of IAQ and ventilation, the impacts of CO₂ on building occupants, the measurement of CO₂ concentrations, the use of CO₂ to evaluate and control outdoor air ventilation, and the relationship of indoor CO₂ to airborne infectious disease transmission.
