Plant Emits HFC-23 That Does More Climate Damage Than All City Cars

"Executives at Chemours promised at the White House in 2015 to try to abate the emissions. Now, they say it will take two more years."

"LOUISVILLE, Ky. — A chemical plant here that makes a raw material for everything from Teflon to lubricants used on the International Space Station also appears to do more damage to the climate than all of this city’s passenger vehicles.

The Chemours Louisville Works along the banks of the Ohio river is the nation’s largest emitter of a climate super-pollutant known as hydrofluorocarbon-23 (HFC-23). As a greenhouse gas, the chemical is 12,400 times more potent than carbon dioxide, the primary chemical compound responsible for warming the planet, and could be eliminated with low cost, existing technology.   

Following inquiries about emissions from the plant by Inside Climate News, Chemours announced a plan Monday to curb those emissions by the end of 2022. However, the company hasn’t met its own commitment to install pollution controls since company officials pledged at a White House gathering in 2015 “to control and, to the extent feasible, eliminate by-product emissions of HFC-23 at all its fluorochemical production facilities worldwide.”"
