I thought CFCs were a think of the past?
... most air conditioning units contain chemical refrigerants (CFCs and HCFCs) that, if released, “have 1,000 to 9,000 times greater capacity to warm the atmosphere than carbon dioxide”. Phasing out the use of CFCs & HCFCs in new units and capturing the refrigerants in discarded units can prevent global warming to such a degree that it's the #1 way to mitigate the effects of climate change.
