What is the impact of HFCs on climate change?

HFCs, or hydrofluorocarbons, are synthetic compounds frequently used in refrigeration, air conditioning, and aerosol propellants. Their impact on climate change is predominantly characterized by their global warming potential (GWP).

The correct answer highlights that HFCs have a high global warming potential compared to CO2. This means that while HFCs are often used as alternatives to ozone-depleting substances, they can trap heat in the atmosphere at significantly higher rates than carbon dioxide. For instance, some HFCs can have a GWP thousands of times greater than CO2 over a 100-year period, making them potent greenhouse gases.

This contribution to the greenhouse gas emissions from HFCs necessitates regulation and a transition to more environmentally friendly substances, aligning with global efforts to combat climate change and reduce the power of these gases in the atmosphere. Understanding the GWP of substances like HFCs is crucial for evaluating their role in climate dynamics and informing policy and technological choices in the industry.
