A method of reducing at least one atmospheric oxidising pollutant, such as ozone, with a reducing agent comprises contacting the reducing agent with the at least one atmospheric oxidising pollutant, wherein the reducing agent comprises a precious metal-free trap material, such as a zeolite, including at least one trapped atmospheric reducing pollutant, e.g. a hydrocarbon, whereby as the at least one atmospheric oxidising pollutant is reduced the at least one trapped atmospheric reducing pollutant is oxidised.
