Flat TV Chemical Poses a New and Serious Greenhouse Gas Threat. UKPress.com, July 3, 2008. "Soaring demand for an industrial chemical used to make flat-screen televisions may be posing a global warming threat, say scientists. The gas, nitrogen trifluoride, is 17,000 times more powerful as a greenhouse gas than carbon dioxide. Yet it is not covered by the Kyoto protocol on emissions, because it was only made in tiny amounts when the agreement was signed in 1997. Today the gas is said to be accumulating in the atmosphere, although its levels have not been measured. Scientists have calculated that it has a half-life in the atmosphere of 550 years. Nitrogen trifluoride, or NF3, is used in the electronics industry mainly to flush out the by-products of chemical vapour deposition. This is the process by which thin films are deposited for liquid crystal displays (LCDs) - used in flat screen TVs - or silicon chips."
