Aluminum reduction technology: PFC emissions reduction

In December 1997, high-level representatives from 160 countries met in Kyoto, Japan, for the Third Conference of Parties to the United Nations Framework Convention on Climate Change and agreed to the Kyoto protocol. The protocol states that industrial countries must achieve a 5,2% reduction of their collective emission of greenhouse gases over the 2008 to 2012 period. The PFC's (CF4 and C2F6) are among the greenhouse effect gases targeted by the agreement These gases are emitted during so-called anode effects. This phenomena will be described and the factors influencing its frequency and duration will be detailed in order to understand how PFC emissions can be reduced.
