A greenhouse gas and carbon accounting profile was developed for the U.S. forest products industry value chain for 1990 and 2004-2005 by examining net atmospheric fluxes of CO(2) and other greenhouse gases (GHGs) using a variety of methods and data sources. Major GHG emission sources include direct and indirect (from purchased electricity generation) emissions from manufacturing and methane emi...
In anticipating future rates of adoption of new technology in forest products, several uniquely important factors come into play. In this respect, the role of innovations imported from other industries, the effect of raw material shortages, the importance of economic factors in adoption of innovations, and the problems presented by the heterogeneity of wood raw material and finished products ar...
Forests in boreal and temperate forest-ecosystems have importance for carbon balance since they sequester large amount of atmospheric carbon by uptake of carbon-dioxide during photosynthesis, and transfer and store carbon in the forest ecosystem. Forest material can be used for bio-fuel purposes and substitute fossil fuels, and supply wood products, which can replace carbon-and-energy-intensive...
Currently, around half a billion acres are certified around the world by the world's top three certification organizations and this number continues to grow rapidly every day. However, consumer knowledge of sustainable forest management and forest certific ation does not appear to be growing. This lack of consumer awareness could be the reason why there is little evidence of a price premium for...
The different uses of wood result in a hierarchy of carbon and energy impacts that can be characterized by their efficiency in displacing carbon emissions and/or in displacing fossil energy imports, both being current national objectives. When waste wood is used for biofuels (forest or mill residuals and thinnings) fossil fuels and their emissions are reduced without significant land use change...
