CO2 doesn't have exactly the same relationship with pollutants from non-human sources that it does with human emissions. Off-gassing from setting up materials, furnishings, cooking, cleansing and electrical goods may very well be independent of occupancy [30] e.g., Offermann found low CO2 degrees together with dangerously high amounts of formaldehydes [31]. However wherever you will find very low ventilation fees you will find rather higher pollutant concentrations from both human and non-human sources, and so making use of CO2 as being a proxy for ventilation level in cases wherever occupancy is known is really a justifiable approach.
