Quizplus · Accepted Answer

Chlorofluorocarbons (CFCs) have been phased out in the United States and other countries since the 1990s due to their harmful effects on the ozone layer. The Montreal Protocol, an international agreement signed in 1987, has led to a significant reduction in the production and use of CFCs worldwide. While some limited exemptions for CFCs still exist for specific uses, their overall use has been greatly reduced.
