In the United States when will all HFCs be phased out?

• A. 2025
• B. 2035
• C. 2030
• D. 2040

Answer: (C)

The main idea is how the U.S. is reducing use of high-GWP HFCs through federal regulation. Under the AIM Act, the EPA implements a phasedown plan that dramatically limits the production and import of HFCs, accelerating replacement with lower-GWP substances and alternatives. This plan sets a milestone around 2030 when the big portion of HFCs will be phased out for new equipment and most applications, pushing remaining reductions into subsequent years. That’s why 2030 is the best answer here: it represents the primary phaseout milestone used in U.S. regulatory timing. After 2030, further reductions continue toward the longer-term goals, but the 2030 target is the key turning point most commonly cited.
