Which of the following protocols did aim for reducing emission of chlorofluorocarbons into the atmosphere?

Step-by-step solution

Ozone depletion refers to the phenomenon of reductions in the amount of ozone in the stratosphere. The problem of ozone depletion is caused by high levels of chlorine and bromine compounds in the stratosphere. As a result of depletion of the ozone layer, leading to the adoption of the Montreal Protocol banning the use of chlorofluorocarbon (CFC) compounds, as well as other ozone-depleting chemicals such as carbon tetrachloride, trichloroethane (also known as methyl chloroform), and bromine compounds are known as ha
