not to forget epa disallowing, under lobbying from dupont & ici,
hydrocarbon drop-in replacements to r-12 that are barely more of a fire
hazard than a cigarette lighter, especially compared to a gasoline tank.

but what's this about hcf's (& hfc's?) having greater ozone depletion than
claimed?  some are potent greenhouse gasses, i know, but i thought leaving
an H on made the whole molecule much more reactive in the troposphere?
