The Kyoto protocol covers six categories of greenhouse gas (GHG) emissions: carbon dioxide 6500 Primary Aluminium production 80%, CFC alternatives.

Eles são compostos pertencentes a função química dos haletos orgânicos que são estruturas que apresentam halogênios ligados à cadeia carbônica. Researchers at each site collect air samples and send them to a central laboratory, where the air is analyzed for CFC-11 and many other trace gases. The weekly measurements, from sites around the world, give an accurate average picture of the chemical species circulating in the global atmosphere.

However, F-gases are powerful greenhouse gases, with a global warming effect up to 23 000 times greater than carbon dioxide (CO 2), and their emissions are rising strongly..

CFCs are particularly harmful when released into the atmosphere because of their destructive reaction with O-zone particles, which provide the Earth with a protective layer against UV radiation. By the 1990s damage to the atmosphere was discovered by British Scientists in the Antarctic. Gases such as CFC’s had damaged the ozone layer, creating a huge hole through which dangerous ultraviolet light could penetrate. Where the hole in the ozone layer developed, these dangerous rays penetrated and reached the earths surface. voluntary action plans to control emissions of three CFC alternatives in development, utilization, leakage prevention, and thorough management of gases.
