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.

By reducing yields and thereby food availability, the significant effects of global warming projected on crops will ultimately have an impact on not only food security but also feed and food safety, with mycotoxins being one of the most significant food safety risks impacted by climate change. Future shifts in temperature, precipitation, and atmospheric CO₂ concentration are anticipated to increase the risk of mycotoxin contamination of cereal crops in the field and may have an effect on where specific cereals, mycotoxigenic fungi, and their mycotoxins are distributed
