R22 phase out dates
Hole in ozone layer is discovered over Antarctica in 1985.Because of this hole, Ultraviolet light can reach the earth and harm both the humans (skin cancer) and plants. In 1987, USA and other developed nations signed Montreal Protocol as an effort to protect ozone layer by reducing the use of CFC and HCFC .In 1993, the Schedule to end CFC and HCFC are announced. The production of CFC ended on 1996 and all ozone depleting substances (HCFC including R22) will face a complete ban on 2030.

A to Z of Refrigerant leak detectors
Leaks increase the cost of running air conditioner systems as it reduces the cooling efficiency and in turn increases the electricity consumption. Another adverse effect is on ozone layer. All systems leak refrigerant. One pound in two years is acceptable but if it leaks more than that, we need to repair the leak.
Refrigerants are covered under European fluorinated gas regulations (F GAS REGULATIONS).Check below points
How to retrofit your old R12 Car AC to R134a
All car models built before 1995 uses R12 as refrigerant for car AC system. Since then R12 is replaced by R134A because of lower GWP. You cannot use R134A in car AC’s deigned for R12 as R134A operates at a much higher pressure.
