ReThink History: The Price of a Tonne

A tonne of carbon dioxide is the strangest commodity ever traded. Nobody wants it, its value is the value of its absence, and the whole market rests on two things no one can see: the tonne itself, and the world in which it was emitted. Since 1997 we have built, broken and rebuilt markets for that tonne — Kyoto's flexible mechanisms, Europe's emissions trading system and the five-billion-euro tax carousel that looted it, California's cap-and-trade and its forest offsets, the United Nations scheme to pay tropical forests to stand, and a voluntary offset market that touched two billion dollars a year and then lost most of it when journalists and scientists found that most of what it sold did not exist. Fourteen episodes walk that history with dates and sources: the Chinese and Indian refrigerant plants paid more to destroy their waste gas than to make their product; the phantom rainforest credits Disney, Shell and Gucci bought, and the registry rebuttals that followed within hours; the hundred-year wildfire insurance fund that burned through in a decade; the World Bank carbon pioneer indicted over cookstove data, who denies the allegations and has not been tried; the satellites now trying to weigh the world's forests from orbit, and the one that cannot legally switch on over America; and the carbon border charge that went live on Europe's imports in January 2026. A coda then takes the restoration forestry almost everyone agrees on — thinning, cultural and prescribed fire, a native understory — and asks whether any carbon market on earth can pay for it. Compiled by a physician who spent eighteen months in 1976 and 1977 at a Forest Service laboratory in Moscow, Idaho, cutting Douglas-firs into disks and counting their rings for the growth model that still projects every forest-carbon baseline in California, and who now builds software for this market. Every over-crediting finding is presented with the registry's or regulator's rebuttal and its date; every pending criminal matter is described in the present tense with the presumption of innocence. AI-narrated from a fully cited research dossier for every episode.
