Sulfur Hexafluoride & Computers

I still fear it's too late for us to change our ways in time, but hopefully mankind will prove me wrong..

Sulfur Hexafluoride & Computers


California regulators Thursday adopted the world's first mandatory measures to control highly potent greenhouse gases emitted by the computer manufacturing industry.

The new rules would cover 85 plants, mostly in Silicon Valley. They require most computer chip makers to slash releases of sulfur hexafluoride and other fluorinated gases by more than half over the next three years.

The sulfur hexafluoride chemicals are used in small amounts but "pose a danger to the planet because they have such a high capacity to trap atmospheric heat," said Mary Nichols, chairwoman of the Air Resources Board.

The fluorinated gases are 6,500 to 23,900 times more potent than carbon dioxide, a greenhouse gas emitted by automobiles, power plants and refineries, among other sources. A single pound of sulfur hexafluoride has the same heat-trapping potential as 10 metric tons of carbon dioxide, or an automobile trip around the Earth.
