In Canada, summer will soon be upon us. As temperatures rise, over 55% of households across Canada will turn on their air conditioners.
Between 1928 and 2010, the most common coolant in our air conditioners and fridges was Freon, a refrigerant comprised of chlorine, fluorine and carbon – or chlorofluorocarbon (CFC). Although Freon was most commonly used in refrigeration, it was also widely used in aerosol-spray containers. Due to its negative impact on the earth's ozone layer, the Canadian government began to phase it out in 2010.
