The Montreal Protocol outlawed halogenated hydrocarbons with high ozone depletion potential because of their negative effects on the ozone layer, which protects the planet from ultraviolet radiation. Modern refrigeration, air conditioning, and heat pump systems use greenhouse gases that are subject to the Kyoto Protocol's time-barred permission period. Both the Paris Climate Accord and European Union legislation place a strong emphasis on the gradual phase-out of the use of harmful synthetic refrigerants in order to lessen ozone depletion and reverse the effects of climate change. The use of natural refrigerants has no discernible impact on the amount of greenhouse gases (GHG) in the atmosphere. Extensive research is being conducted globally to retrofit and modify existing cooling and heating systems using natural refrigerants.
