Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) have long been recognized as potent contributors to both ozone depletion and climate change. Despite their role as refrigerants and propellants, these synthetic compounds have a staggering global warming potential, many thousand times greater than CO₂. HCFC is considered to be around 2,000 times, CFC more than 10,000 times more potent as a greenhouse gas than CO₂. Recognizing the environmental threats posed by these substances, international efforts have been made to curb their production and use.

In response to the detrimental impact of CFCs and HCFCs on the ozone layer and their role in exacerbating climate change, a series of international agreements, such as the Montreal Protocol, have been established. These agreements banned CFCs and phased out the production and consumption of HCFCs, leading to a global reduction in the use of CFCs and HCFCs. The success of these initiatives is evident in the gradual elimination of these compounds from various industrial processes and consumer products.

One crucial aspect of addressing the legacy of CFCs and HCFCs involves managing existing stockpiles of these refrigerant gases. Climate projects are actively engaged in the responsible disposal of old inventories to prevent their inadvertent release into the atmosphere. The destruction of these gases is a crucial step in mitigating their impact on both ozone layer depletion and global warming. By proactively managing and eliminating old stockpiles of CFCs and HCFCs, these climate projects play a vital role in safeguarding the environment.
