As co-discoverers of “Decarbonizationâ€, we were amused to find a container of Eucarbon (“Good carbon†in Greek) made by a Viennese manufacturer early in the 20th century. The old label advises that the product is a mild purgative and disinfectant, and one might take 1-2 tablets after breakfast, lunch, and dinner with some water. It turns out the same company, Trenka, still makes the product. Should attendees at global climate change conferences take Eurcarbon?
