What is the estimated lifetime range of CFSs?

Chlorofluorocarbons (CFCs) are synthetic compounds that have a long lifespan in the environment due to their stability and resistance to degradation. The estimated lifetime range of CFCs can extend from 20 to 100 years, and in some cases, they can persist even longer. Their molecules are designed in a way that makes them robust against natural atmospheric processes. This longevity is a concern due to their contribution to ozone depletion and their role as greenhouse gases.

Understanding the extended atmospheric lifetime of CFCs is crucial for evaluating their environmental impact and guiding policy decisions regarding their use and regulation. This recognition also underscores the importance of transitioning to alternatives that pose less harm to the ozone layer and the environment.
