yup the environmentalist wako-s, about a year ago, decided to pressure pharma companies to switch their inhalers to the HFA version, because they claimed traditional MDI's had chloroflorocarbons (CFC's) that ruined the air.

Do you have any news articles that can confirm this? According to the regulations set forth in the Montreal Protocol, the use of CFCs as an aerosol propellant has been banned for nearly 2 decades. I find it extremely hard to believe that pharmaceutical companies would be manufacturing MDIs that use CFCs.
Did you mean to say that they use ODS? (Ozone depleteing substances?) those are still being used (e.g. air conditioner coolant), but are highly regulated.
Oh, as a side note...I'm an environmental scientist but not an environmentalist. There's a subtle difference <img src="i/expressions/face-icon-small-smile.gif" border="0">
