"A California man was arrested and charged Monday with allegedly smuggling potent, planet-heating greenhouse gases from Mexico, marking the first such prosecution in the US, according to a statement from the US Attorney’s Office for the Southern District of California.
Michael Hart, a 58-year-old man from San Diego, pleaded not guilty to smuggling hydrofluorocarbons, or HFCs — commonly used in air conditioning and refrigeration — and selling them for profit, in a federal court hearing Monday.
According to the indictment, Hart allegedly purchased the HFCs in Mexico and smuggled them into the US in the back of his truck, concealed under a tarp and tools. He is then alleged to have sold them for a profit on sites including Facebook Marketplace and OfferUp."
