The Montreal Protocol from 1987 banned gases and refrigerants that deplete the ozone layer. This is something that even a backbencher in an elementary school science class could tell you. But what is less commonly known today in 2025, is that there are still millions of gas canisters all over the world containing dangerous and banned ozone refrigerants like R-12, either sitting around in warehouses, lying around in remote farms or being illegally traded. These gases are both ozone depleting substances and greenhouse gases, so they’re absolute environmental stinkers. But Tradewater’s work, essentially making them an agent of the Montreal Protocol, often involves shipping rotting refrigerant gasses halfway across the world to their secure destruction facilities. And when customs agencies and port authorities that they encounter midway, well-versed in the Basel Convention (the treaty moderating the shipment of waste), see what they are trying to ship, it looks an awful lot to them like waste being shipped across the world. Ana Fernandez, a Logistics Associate at Tradewater, joins us today to talk about how her work places her right in between two environmental treaties, and how one of them, the Basel Convention, ends up blocking her efforts to achieve the aims of the Montreal Protocol. Join us as we unpack a journey involving tense international negotiations, complex bureaucracy at security checkpoints and how in this odd instance, one race to save the world is being blocked by another.
