Introduction
 
Under the Kyoto Protocol, there are six gases that count towards an emissions reduction target. They are CO2, CH4, N2O, HFC, PFc and SF6. These last three are human-made gases, sometimes called 'potent industrial greenhouse gases' (PIGGs) or 'fluorinated greenhouse gases' (f-gases).

HFCs, PFCs and SF6 have extremely high global warming potentials and are being emitted at a rapidly increasing rate - predictions indicate emissions could rise 150% between 1995 and 2010. Fortunately they are largely replaceable by commercially available natural compounds like hydrocarbons, ammonia and CO2, or by alternative technologies and practices.
