Scientist warns of climate risk from flat-screen TVs

Rising demand for flat-screen televisions could have a greater impact on climate change than the world's largest coal-fired power stations, the Guardian reported a top scientist as warning.

Manufacturers use a greenhouse gas called nitrogen trifluoride to make the TVs, which is 17,000 times more potent than carbon dioxide, the report said.

No one knows how much of it is being released into the atmosphere, the report said. But the industry produces around 4,000 tonnes of the gas each year. Emissions of the gas are not restricted by the Kyoto protocol or similar agreements.
