The answer to this question is no. Beeswax candles do not produce any carbon monoxide. The reason for this is that beeswax burns at a higher temperature than some other waxes, such as soybean or paraffin wax, which are typically found in standard "pillar" candles. The heat, and therefore the release of carbon into the air during combustion, is significantly lower because of the high melting point and natural self-combustion properties of beeswax. Since the temperature is higher, the carbon monoxide and other gaseous emissions are also significantly lower.
