What does the Safe New Alternatives Policy program (SNAP) do?

The Safe New Alternatives Policy (SNAP) program, established by the U.S. Environmental Protection Agency (EPA), is designed to evaluate and recommend safer alternatives to substances that deplete the ozone layer. The program is comprehensive in its approach, which includes identifying suitable substitutes for all ozone-depleting substances rather than limiting its focus to just one group or type.

By specifying alternatives for these harmful substances, the SNAP program not only helps in the transition away from ozone-depleting chemicals but also aims to ensure that the alternatives chosen are themselves safe for human health and the environment. This alignment with broader environmental protection goals reinforces the program's commitment to maintaining both a healthy atmosphere and a viable option for industries and manufacturers.

On the other hand, while listings of unacceptable alternatives are also important for steering industries away from harmful choices, the core function of the SNAP program revolves around providing specific, safe alternatives rather than simply disqualifying options. The program also takes a holistic view on environmental impacts beyond just ozone depletion, so a focus solely on ozone depletion potential or global warming potential does not capture the full scope of what SNAP does.
