Well, yes and no. Usually they are filled with 1,1-Difluoroethane, which is heavier than butane, and I believe has a very very low global warming potential.

However, some of them do ship with butane as the propellant, if you look closely.

This one, however, I refilled with butane.

Before anyone says it, yes I understand the risks of refilling canisters, especially off label like this. I've done tons of research and due diligence, taking into account the different vapor pressures and molecular weights of the gases. As well as leaving plenty of safety margin in the headspace in the can. I'm well below the safety margin of the can even when it had difluoroethane in it, let alone the fact that it could handle significantly more.
