Atmosphere

This section deals with the impacts of climate change on ozone loss, which is projected to surpass that caused by chlorofluorocarbons (CFCs) in the upcoming decades. In addition, considering that ozone-depleting substances are also potent greenhouse gases, issues covered include those related to efforts carried out under the Montreal Protocol, notably the phase-out of CFCs, which is greatly reducing emissions of carbon dioxide equivalent and delaying climate change.
