After a decade of deliberation, the US state of California may soon let its companies meet part of their emission-reduction obligations by saving forests in places like the Mexican state of Chiapas.

We all make mistakes -- that's why pencils have erasers and renters have insurance. Not all mistakes, however, are equal. If we mess up a math test, we can erase and start over; but if we burn the neighbor's house down, we can't "un-burn" it by labeling it a mistake. Instead, we have to offset our damage by paying to rebuild it.
