"The EPA’s uncoordinated greenhouse gas disclosures make it hard to determine the plant’s carbon footprint, and even confused the city’s technical consultants."

"LOUISVILLE, Kentucky—The Chemours Louisville Works emits a chemical feedstock and a separate gas byproduct that do more damage to the climate than 750,000 passenger vehicles, and far more than the Environmental Protection Agency’s main industrial greenhouse gas inventory indicates.

Chemours’ most harmful climate super-pollutant is the byproduct, hydrofluorocarbon-23 (HFC-23), a potent greenhouse gas that produces 12,400 times more warming than carbon dioxide, the main chemical compound responsible for climate change.  

But the plant also emits hundreds of tons of hydrochlorofluorocarbon-22 (HCFC-22), a chemical ingredient in everything from Teflon to lubricants used on the International Space Station. In addition to being a climate super-pollutant that is 1,760 times more effective at warming the atmosphere than carbon dioxide, HCFC-22 also destroys atmospheric ozone that helps protect the Earth from harmful ultraviolet rays."
