    What do CFC and HCFC stand for. Which one is the harmful one to the ozone.

    Technically both. HFC's are "harmless".

    To expand on that, CFCs are the more harmful of the two.

    How many times must one fix something before it is fixed?

    Who said HFC's were harmless! They don't have the ozone depleting potential, but they are a greenhouse gas, so they have a greater global warming potenial. So how did we win with the switch?

    CFCs and HCFCs are also so called GHGs.

    All refrigerants should be recovered anyway.
    General public's attitude towards our energy predicament: "I reject the reality of finite resource depletion and substitute it with my own; energy is infinite, we just need an alternative storage medium to run the cars on. The economy can grow indefinitely - we just need to "green" everything! Technology is energy! Peak what?"

    I think that, theoretically, all halogens are harmful to the ozone layer. That would be chlorine, fluorine, bromine, iodine, and astatine.
    No reserve. No retreat. No regrets.

    For those who have fought for it, freedom has a sweetness the protected will never know.

    But HFC's have no chlorine and therefore have no ODP (Ozone Depletion Potential)

    As example HFC (r-143a) has elements Hydrogen, Flourine & Carbon with an ODP of zero.

    I am studying for my EPA 608 Certs as we speak so if this is false (info from my study guide) please let me know!!!

    I believe that free available elemental forms of ozone depleting substances are what count. Chlorine, fluorine, bromine, iodine, and astatine probably don't stick around long before reacting with other substances.

    HCFC gasses have much lower ODP than CFCs because they're less stable and (for the most part) break down long before they reach the ozone layer.

    HFC's have fluorine...a halogen. But at any rate, I think it's all bunk.
