What statement is true regarding HydroFluoroCarbons (HFCs)?

The statement that many HydroFluoroCarbons (HFCs) have a significant global warming potential is indeed true. HFCs are synthetic compounds commonly used as refrigerants, propellants, and solvents, and they are known for their ability to trap heat in the atmosphere. This characteristic gives them a high global warming potential compared to other greenhouse gases. Despite being designed to replace ozone-depleting substances, like chlorofluorocarbons (CFCs), HFCs can still contribute substantially to climate change due to their long atmospheric lifetimes and potency as greenhouse gases.

The significance of HFCs in global warming has led to international agreements aiming to phase them out, specifically the Kigali Amendment to the Montreal Protocol. This is in recognition that although HFCs do not directly deplete the ozone layer, they still pose a serious challenge in combating climate change. Thus, acknowledging their substantial impact on global warming is critical in discussions about climate policies and sustainable practices.
