Don’t Let Your Car’s Air Conditioner Leak

In the U.S. leakage from auto air conditioners is the largest single source of emissions of chlorofluorocarbons (CFCs), which damage the protective ozone layer and add to global warming. The CFCs from one auto air conditioner can add the equivalent of 4,800 pounds of CO2 emissions a year.
In addition, if your car has an air conditioner, make sure its coolant is recovered and recycled whenever you have the car serviced.
