Most compressed air duster cans sold in the U.S.

use a particular class of GHGs, referred to as hydrofluorocarbons, or HFCs, as the propellant.

However, HFC-134a is much more damaging to the climate with a global warming potential (GWP) of 1,300 and an atmospheric lifetime of about 14 years..

What happens if you shake a can of compressed air?
