10 Apr 1988 Chlorofluorocarbons (CFCs) were invented in 1928 by combining molecules of hydrocarbon, chlorine and fluorine. They are used in liquid or
gases for CFC-12. - In 1993-1996, HFC-134a used as a replacement gas for CFC-12 in cars. CFC-11 - Used in insulating foam pre-1990. - Used in large chillers for air-conditioning and industrial applications. Eliminated in 1993. HCFC-141b - Used in insulating foam post 1994 - Used as the predominant refrigerant domestic systems. Eliminated in 2003.

Before its ban, CFC-11 was commonly used to manufacture insulating foams. However, the usage of CFC-11 has been prohibited since 2010. So, the researchers expect that any CFC-11 in the atmosphere right now should be coming from old foams in buildings and refrigerators, which should eventually decline with time.

HFCs, CFCs and HFCs are a subset of a larger group of climate changing gases called greenhouse gases (GHGs). Taken together greenhouse gases are expected to warm the planet by 2.5 to 8 degrees Fahrenheit by the end of century. HFCs, CFCs and HFCs contribute an estimated 11.5% to present-day effect of GHGs on climate and climate change. Chlorofluorocarbons and Ozone Depletion · Widespread use of CFCs.
2 Jun 2007 Chlorofluorocarbon (CFC) is a gaseous compound made of three elements, carbon, chlorine and fluorine (and sometimes hydrogen).

EIA has calculated that illegal CFC-11 use in China may have created a total bank of almost 4 gigametric tons of CO 2 equivalent between 2013 and 2017 contained in existing polyurethane foam products, much of which is yet to be emitted into the atmosphere. Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth. Carbon dioxide (0.04%), nitrous oxide, methane, and ozone are trace gases that account for almost 0.1% of Earth's atmosphere and have an appreciable greenhouse effect. [] eliminar los CFC reduciría las emisiones de gases de efecto invernadero [] de la empresa en 52,5 millones de toneladas del dióxido de carbono equivalente para 2025 y ahorraría un 15 por ciento de sus costos de energía, según el presidente de la empresa Muhtar Kent. CFCs are much more potent on a per molecule basis than CO2 and some other greenhouse gases, even though the emissions of those gases are larger than CFC emissions by several orders of magnitude. By simply replacing the CFCs with hydrochlorofluorocarbons (HCFCs) or hydrofluorocarbons (HFCs), the proportional global warming impact of these chemical emissions in the future would change as
