It is not well known, but the most potent greenhouse gas is, surprisingly, neither carbon dioxide nor methane, but a colorless, odorless, and inert gas known as sulfur hexafluoride (SF6). With a global warming potential 23,900 times that of CO2 and being synthetic in nature (it is not absorbed on destroyed naturally), rising SF>6 concentrations are of major concern. Currently, electrical utilities and equipment are responsible for consuming 80% of the 10 000 tons of SF6 produced every year, an amount which is growing with the increasing global production and demand for renewable forms of energy, such as wind and solar. Can chemists and engineers rise to the challenge of solving the looming SF6 problem?
