The rising demand for flat-screen televisions could have a greater impact on global warming than the world’s largest coal-fired power stations, a leading environmental scientist warned yesterday.
As a driver of global warming, nitrogen trifluoride is 17,000 times more potent than carbon dioxide, yet no one knows how much of it is being released into the atmosphere by the industry, said Michael Prather, director of the environment institute at the University of California, Irvine.
Writing in the journal Geophysical Research Letters, Prather and a colleague, Juno Hsu, state that this year’s production of the gas is equivalent to 67m tonnes of carbon dioxide, meaning it has “a potential greenhouse impact larger than that of the industrialised nations’ emissions of PFCs or SF6, or even that of the world’s largest coal-fired power plants”.
