The strict, comprehensive protections of the Clean Air Act must be maintained and enhanced if we are to keep in place effective federal programs that deal with urban smog, toxic air pollution, acid rain, and ozone depletion. State and local clean air initiatives should advance and improve national efforts; for example, moving forward with stricter clean air and fuel efficiency standards, and with vehicle and fleet conversions.
We should recognize the positive contributions for controlling ozone-destroying substances that have been made by the Montreal Protocol of 1987 and subsequent amendments thereto. Problems still exist, however. Some of the chemical replacements for CFCs also damage the ozone layer or are potent greenhouse gases. These include hydrofluorocarbons (HFCs) and Very Short-Lived Substances (VSLS) such as dichloromethane and other chlorine gases.
We should support further research on the damaging effects of VSLS on the ozone layer and finding replacements for those causing destruction of ozone, and immediately phasing out their use. We call for updated amendments to the Montreal Protocol to keep it consistent with current scientific findings regarding threats to the ozone layer.
