The Montreal Protocol established an international agreement to make a concerted effort to reduce emissions that deplete the ozone layer. Since many refrigerants have an effect on the ozone layer, this was a key piece of legislation for the HVAC community.
It was agreed that several refirgerants will be banned and others phased out. The goal was to move from chloroflorocarbons (CFCs) to hydrochoroflourocarbons (HCFCs) and ultimately Hydroflourocarbons (HFCs).
CFCs are no longer sold and cannot be recharged into systems. HCFCs are being phased out with the goal of having them gone by the year 2030.
