The production of a chemical molecule such as the nitrogen trifluoride or NF3, which is reported to be a greenhouse gas 17,000 times more potent than CO2 is increasing significantly for industrial uses (eg for flat screens and computers) and could reach by 2010 a quota of eight tonnes per year that would correspond to about 130 million tonnes of CO2, which is generally small in total but not negligible for the environmental impact especially from the moment that has been replaced according to the directives of the Kyoto Protocol of 1997 to the perfluorocarbons or PFCs. Other chemical compounds have been reported for their potential environmental hazard such as methane, nitrogen dioxide, sulfur hexafluoride, hydrofluorocarbons.. since they all tend to fuel the greenhouse effect and many nations are discussing how to limit the production of these little healthy chemical molecules.
