Using representative sample of partial cut and clear-cut harvests from Northern California, we estimated the financial and climate benefits of the harvested products Ton for ton, sawlogs generate far more climate benefits than wood chips initially used for energy. The presence of wood-fired energy plants provided forest. forest managers with the opportunity to economically utilize residues that otherwise would have decomposed in the forest. The energy captured at harvest sites, sawmills, and waste-to-energy plants in urban areas are additional climate benefits not included in the forestry chapter of national greenhouse gas in ventories. When current utilization practices throughout the full wood products use cycle are considered, the total estimated climate benefits per unit of harvest volume are two times larger than estimates based on historical wood utilization coefficients. A full accounting of the climate benefits across all sectors is necessary to develop accurate estimates of the climate benefits associated with harvested products under different forest management regimes.
