B: CFC production in the United States will be phased out by 2030
C: CFC production in the United States will be phased out by 2010
D: CFCs are no longer used in the United States

参考答案: A

本题解释:
Under the Montreal Protocol, CFC production in the United States ended in 1995. To implement the Montreal Protocol, the EPA established Section 608 of the EPA Clean Air Act for regulating the use and recycling of ozone-depleting compounds.

Many refrigeration systems of existing buildings still use CFCs in the United States. For these projects, the project team can take 5 years from project completion to phase out CFC-based refrigerants, as long as the annual leakage rate of CFC-based refrigerants is reduced to 5% or less.
