Hydrofluorocarbons (HFCs) are primarily linked to which environmental concern?

Ozone depletion
Global warming
Water pollution
Soil erosion

The correct answer is: Global warming

Hydrofluorocarbons (HFCs) are primarily linked to global warming because they are potent greenhouse gases that trap heat in the atmosphere. While HFCs do not deplete the ozone layer, which is a significant concern associated with other chemicals like chlorofluorocarbons (CFCs), they have a high global warming potential (GWP). This means that even in small quantities, HFCs can contribute significantly to climate change by enhancing the greenhouse effect. Their use has increased significantly as alternatives to ozone-depleting substances, but their impact on global warming is a key issue in environmental discussions and regulations.
