Looking at the gases with the highest GWPs, there was a 32 % decrease for SF 6, a 12 % decrease for NF 3 and a 13 % decrease for PFCs. There is also an HFC which is up to 12,500 times more potent than CO2. If the global use of HFCs continues to grow at the current rate, their contribution to the greenhouse effect will increase up to 10 percent of that of the main greenhouse gas CO2 in 2050. the Australian HVAC&R market has enjoyed a period of HFC use without legislative restriction. This is due to change at the end of 2017 with the introduction of HFC import quotas, which are the Australian government’s chosen mechanism for meeting its international obligation to phase down the use of HFC gases under the amended Montreal Protocol. The HFC gases are used extensively in every day RAC systems.
The world has come together to ban HFC refrigerants such as R-134a, R-404A, and R-410A across the world by the year 2100. Yes, that’s right 2100. While that may sound a ways away it is worth mentioning that the WHAT IS THE F-GAS/HFC PHASEDOWN? The EU F-gas regulation includes a method of forcing end users to move away from using high global warming potential gases to more environmentally friendly gases in stationary refrigeration, air conditioning and heat pump equipment very rapidly by limiting how much gas can be placed on the EU single market each year. A time horizon of 100 years is used by regulators (e.g., the California Air Resources Board).

HFC climate IMPACTS HFCs are potent greenhouse gases that can be hundreds to thousands of times more potent than carbon dioxide (CO 2 ) … HFCs (hydrofluorocarbons) are the third generation of fluorine-based gases.

Hydrofluorocarbons (HFCs) are by far the most relevant F-gas group from a climate perspective, although they are relatively short-lived. The other two F-gas groups, perfluorocarbons (PFCs) and sulphur hexafluoride (SF6), can remain in the atmosphere for thousands of years.

Fluorinated Greenhouse Gases, also known as the "F-Gas Regulation.
In 1928 Thomas Midgley Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon (R-12). The name is a trademark name owned by DuPont (now Chemours) for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant.
