title: A carbon balance method for paper and wood products.
abstract: The approach used to track the flow of carbon sequestered in the forest through harvest, processing into products, and final disposition of products is described. The methodology is broadly flexible and applicable to forest-based carbon balance assessments. A carbon balance is computed across all forestland ownerships for the production facility of interest. The balance considers forest uptake, harvest, combustion of fuels, emissions from process steps and losses from product use, disposition and recycling. The method also allows for sensitivity and marginal assessments of a variety of real and hypothetical situations using variable assumptions. Example results for a vertically integrated pulp and paper mill are presented. Results suggest that integrated forest products facilities drawing their raw material from sustainably managed forests can achieve a net positive carbon balance over the product cycle. The amount of net carbon sequestration attributable to such facilities depends upon a number of factors. The most critical of these include net forest growth, the method for allocating the growth in forest carbon among all of those harvesting from the drain area of a given facility, and the use and disposal patterns for the paper or wood products manufactured.
