Impact of the Montreal Protocol

Medium Period 9: 1980–present Environmental Concerns

In the late 20th and early 21st centuries, a range of environmental issues captured the attention of both the public and policymakers. Among these was the growing concern regarding the depletion of the ozone layer, which was largely attributed to the use of chlorofluorocarbons (CFCs) in various products. In response to this environmental hazard, significant international agreements were established to mitigate the damage. One of the most notable of these agreements was the Montreal Protocol, which aimed to phase out substances that deplete the ozone layer. This agreement highlighted the global cooperation needed to address environmental issues.

Considering this context, which of the following actions was a direct result of the Montreal Protocol?

The establishment of a national carbon trading system in the U.S.

The international ban on the production of certain CFCs.

The implementation of stricter automobile emissions standards.

The decision to expand nuclear energy as a primary energy source.
