Finally, lots of recent press reports have focused on the use of nitrogen triflouride (NF3), a highly potent greenhouse gas, in the manufacture of "flat-screen TVs." (Actually, they're only used in making LCDs.) The Green Lantern agrees that NF3 deserves more monitoring, especially now that greater amounts of it have been discovered in the atmosphere than previously estimated. But according to the University of California report that prompted the coverage, even if all the NF3 produced annually escaped into the atmosphere, it would have only 0.44 percent as much impact on global warming as carbon dioxide does each year. Plus, NF3 is used in all kinds of electronics; only a fraction goes toward televisions. So at least for now, the Green Lantern doesn't think NF3 is a reason to avoid upgrading.
