Accelerate phase out of CFCs Base decisions on health and environmental safety on best information PAFT Program for Alternative Fluorocarbons Toxicity testing

Combine resources Co-operate with academic and government research programmes Substantially reduced the usual period of time for environmental and toxicological testing of new chemicals Assisted the rapid phase out of CFCs Cost:$ 11 million (AFEAS), plus $ 24 million (PAFT) > 50 research projects 15 workshops / symposia / conferences >100 peer reviewed papers 40 reports

Milestones 1989 Scientific Assessment of Stratospheric Ozone (“the silver book”) A comprehensive review of the environmental properties of HCFCs and HFCs reviewed in the WMO process and published within two years of the Montreal Protocol being signed, before any reduction in CFC use was required.

Milestones 1989 Scientific Assessment of Stratospheric Ozone (“the silver book”) Total Equivalent Warming Impact (energy conservation is more important than GWP) Over 15% of the electricity generated in the USA is used in refrigeration or air conditioning. Whatever the primary energy source, energy conservation is highly important. Containment of the refrigerant fluid has improved significantly.

Milestones 1989 Scientific Assessment of Stratospheric Ozone (“the silver book”) Total Equivalent Warming Impact (energy conservation is more important than GWP) Trifluoroacetic Acid (TFA) Risk Assessment Environmental TFA is not a problem. The assessment predated the information that showed TFA is predominantly natural.
