What are F-Gases?

Fluorinated greenhouse gas emissions account for about two percent of emissions in the United States and emissions are growing. F-gases, as they are called, are the most potent and persistent of the greenhouse gases. These gases are generally thousands of times more effective than CO2 at trapping heat in the atmosphere, and many remain in the atmosphere for millennia. Due to their high global warming potential, relatively small quantities of these gases can yield large greenhouse gas emissions in CO2–equivalent terms.

Main uses of F-gases:

  • Refrigeration, air conditioning and heat pump equipment are some of the largest sources of F-gas emissions.
  • Some stationary fire protection systems and portable fire extinguishers that currently use HFCs.
  • Mobile air conditioning in cars and light vans currently uses HFCs. Other air-conditioned and refrigerated transport also uses F-gases.
  • Solvents containing F-gases are used to clean components, eg in the electronics and aerospace industries.

Unlike other greenhouse gases, fluorinated gases have no significant natural sources and come almost entirely from human-related activities. They are emitted through their use as substitutes for ozone-depleting substances. Many fluorinated gases have very high global warming potentials (GWPs) relative to other greenhouse gases, so small atmospheric concentrations can have disproportionately large effects on global temperatures. They can also have long atmospheric lifetimes—in some cases, lasting thousands of years. Like other long-lived greenhouse gases, most fluorinated gases are well-mixed in the atmosphere, spreading around the world after they are emitted. Many fluorinated gases are removed from the atmosphere only when they are destroyed by sunlight in the far upper atmosphere. In general, fluorinated gases are the most potent and longest lasting type of greenhouse gases emitted by human activities.
