Yes, although aerosol cans aren’t banned, just the CFC’s that were in them. CFC’s have been banned in the US, Canada, and most Scandinavian countries since 1978. Other parts of the world still allow their use, and aerosol cans account for 25% of the CFC’s in the atmosphere. These stay in the atmosphere for 22 to 111 years, then break down and release chlorine atoms, which break down the ozone layer.
