The Carbon
Loss Register.
An open record of documented carbon-credit loss events, exposures and candidate signals. A loss event carries the document that decided it and the dates that document states; an exposure is a quantity with no date; a candidate is a signal whose cause the source does not state, and is not an established loss. Every row says which it is.
Free to read. Free to cite.
