Dispose of pre-1995 refrigerators, freezers, and air conditioning units properly. These devices use chlorofluorocarbons to function, so leaks release the chemical into the atmosphere.Call your local utility company to see if there is a bounty program in your area that your appliance qualifies for.If not, contact your municipal department of public works to ask how to dispose of refrigerated appliances in your neighborhood.             Don’t buy aerosol products with chlorofluorocarbons (CFC). Although CFCs have been banned or reduced in many applications, the only way to be sure is to check the label on all your hairsprays, deodorants and household chemicals. Opt for pump spray products over pressurized cans, to further reduce your chance of buying CFCs.
           Check your fire extinguishers to find active ingredients. If “halon” or “halogenated hydrocarbon” is the main ingredient, find a hazardous waste center at which to recycle it or call your local fire department for instructions on how to dispose of it. Replace it with a model without this harmful ozone-depleting chemica.
                Nitrous oxide is now the largest ozone-depleting substance released by human activities (as well as a potent greenhouse gas),and it is produced in the internal combustion that powers most cars. In the U.S., about 5% of all nitrous oxide pollution comes from vehicles.To reduce the amount of nitrogen oxide your car produces, consider:Car poolingPublic transportWalkingBikingDriving a hybrid or electric car
