As they say on TV, “Coming up next: Why TVs are hazardous to the environment.”
Just when you think we are getting a handle on emissions issues…Plasma and LCD flat screen televisions are contributing to global warming, a new study has found. A gas used in the manufacturing of flat screen TVs called nitrogen trifluoride (NF3) is estimated to be 17,000 times more powerful than C02.
The production of the gas is equivalent to 67m tones of carbon dioxide. In a study published in the journal Geophysical Research Letters, Michael Prather, director of the environment institute at the
Prather and his colleague Juno Hsu said this year’s production of the gas has “a potential greenhouse impact larger than that of the industrialized nations' emissions of PFCs or SF6, or even that of the world's largest coal-fired power plants.” The claim is a bit questionable though, because Prather admits to not knowing whether the gas is captured on sight, or broken down before release into the atmosphere.
The scientists are particularly concerned because levels of this gas have not been measured. NF3 is not covered by the
“We don't know what's emitted, but what they're producing every year dwarfs these giant coal-fired power plants that are like the biggest in the world," he said in an interview with the Australian Broadcasting Corporation. “And it dwarfs two of the
