A Reduction of Ozone Depletion
Successes and Strengths
Failures and Weaknesses
U.S. costs associated with the Montreal Protocol’s efforts to eliminate the use of chlorofluorocarbons (CFCs) and other ozone-damaging chemicals from 1987 through 2060 vary depending on which assumptions are used, but Environmental Protection Agency estimates that the final tab will range between $40 billion and $60 billion.
Many argue whether or not these costs were worth the benefit because the ozone hole is still quite large in size.
