Refrigerant chemicals

Long-term problem

Because of how air conditioners work, they must contain a substance known as a refrigerant. Most refrigerants in use today^{[ELABORATION needed]} happen to be potent greenhouse gases. They aren't supposed to leak out into the atmosphere - but they sometimes do, if the air conditioner gets old or is disposed of improperly.

This section is incomplete. It needs:

• Quantification - how much of climate change is due to refrigerants
• Solutions - are there any alternatives - refrigerants that aren't greenhouse gases? And are there tradeoffs? ^{[new page needed]}
