By providing ratios of raw material input to output for wood-based forest products in 37 countries, this book helps analysts, policymakers, forest practitioners and forest-based manufacturers to understand the drivers of efficiency, feasibility and economics in relevant sectors. The term "forest product conversion factors" is used to cover a broad spectrum of ratios used in the forest, manufacturing and energy sectors. For the purposes of this publication, "conversion factor" is defined as using a known figure to determine or estimate an unknown figure via a ratio. Almost every aspect of forecasting and analysis involves the use of conversion factors in some way, including silvicultural growth models, biomass calculations, estimates of forest carbon and timber-sale appraisals.
