The Thing the Market Can't Buy

On the Colville National Forest in northeast Washington, the sawmill, the loggers-and-conservationists coalition, and the Forest Service capacity for restoration all exist. The episode asks whether any carbon market can pay to thin small trees and return low-intensity fire, and concludes it cannot, for several different reasons. Thinning costs carbon first, the counterfactual keeps shifting, and soil carbon cannot be measured. The money that works comes from auction appropriations, spent by government.

Still debated

Scientists dispute whether thinning's carbon debt is repaid around year 40 to 51, and whether low-severity fire releases about 70 percent as much carbon as high-severity fire. Estimates of pyrogenic carbon's residence time vary widely, and Indigenous positions on monetizing cultural burning are left unflattened.
