illegal Car Air Conditioning Systems?

These days I think we are all aware of our actions and the impact our actions may have on the environment, except that is maybe of car manufacturers, who seem to slip through the net when it come to car air conditioning and climate control systems within the automotive industry and the omission of refrigeration gases into the atmosphere .

I feel in this day and age almost everybody is aware of the negative impact that refrigeration gases can have on the environment, when set free into the atmosphere, both to the ozone layer and greenhouse gas emissions, yet almost every car manufacturer designs the aircon system so it allows refrigeration gases to perambulate from the cars air conditioning system on a permanent basis until the system is empty and non functional.

The type of air conditioning compressors used in modern cars combined with low quality air conditioning pipe work seems to be a deliberate and more important an unlawful act, as they knowingly by design, allow refrigerant gases to escape into the atmosphere.

Allowing refrigerant gases to escape into the atmosphere is now outlawed under international agreement, so when will vehicle manufactures be held to comply with this supposed environmental protection law?
