International treaties, environment, science and business interests converge on the use and replacement of refrigerant gases.

The issue of refrigerant gases is covered by two international agreements Montreal Protocol (MP) and the UN Framework Contention on Climate Change (UNFCCC). The MP is meant to reduce or do away with gases that cause a hole in the ozone layer that envelopes the Earth — mostly refrigerant gases and solvents. The UNFCCC is meant to bring down emissions of greenhouse gases that warm up the planet.
