‘Unbreakable’ greenhouse gas meets its doom at last
The war on climate change just got a chemical weapon: a way to destroy the carbon-fluorine bonds that make a class of widely used industrial gases so dangerous in the atmosphere. Gases made from carbon, fluorine and chlorine, called chlorofluorocarbons (CFCs), long used as refrigerants, were banned in the 1990s because they damage the ozone […]

Neutralizing Fluorocarbons
Fluorocarbons–common chemicals in which carbon is bound to fluorine–are potent greenhouse gases, and some form toxic compounds that can accumulate in the environment. But neutralizing fluorocarbons has required a process whose high temperature drives up its cost, limiting its adoption. Researchers at Brandeis University report in Science today that they have found a catalyst that […]

Nitrogen trifluoride (NF3): Calls to monitor potent greenhouse gas
A new study indicates that the environmental levels of nitrogen trifluoride (NF3), a powerful greenhouse gas, should be monitored. NF3 was missed out of the last Kyoto protocol in 1997 as it as it was only made in small amounts for niche markets such as rocket fuel and lasers. But since then use of the […]

Nitrogen trifluoride: Environment: Climate risk from flat-screen TVs
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. Manufacturers use a greenhouse gas called nitrogen trifluoride to make the televisions, and as the sets have become more popular, annual production of the gas has risen to […]

Potent New Greenhouse Gas Discovered
MAINZ, Germany, July 31, 2000 (ENS) – Researchers from seven institutions in Germany, the United Kingdom and the United States have detected a previously unreported compound of industrial origin in the atmosphere – trifluoromethyl sulphur pentafluoride (SF5CF3). It is considered the most potent greenhouse gas measured to date. There is no doubt that the new […]

New Greenhouse Gas Identified, Potent and Rare (but Expanding)
Scientists have found rising concentrations of a newly identified gas in the air that traps heat more effectively than all other known greenhouse gases, the dozens of compounds released by industry and the burning of fuels that act like a greenhouse roof and may be warming the global climate. The synthetic gas is extremely rare, […]
