Significant New Alternatives Policy (SNAP) Program
The Significant New Alternatives Policy Program (SNAP), established under the Clean Air Act, allows the EPA to evaluate substitutes for ozone-depleting substances and hydrofluorocarbons (HFCs) targeted by the American Innovation and Manufacturing Act (AIM). This program helps identify safer alternatives to reduce environmental and health risks. Learn how the EPA assesses these substitutes, the submission process, and why these alternatives are crucial for protecting human health and the environment. For more information, visit Protecting Our Climate By Reducing Use of HFCs page.
