With the analytical tool, Frankfurt Harvested Wood Products Model, FPM, the carbon stocks and carbon stock changes of Harvested Wood Products, HWP, either in USE or in LANDFILLS L-F, have been evaluated, each separately, from the readily available statistical data base of the FAO, FAOSTAT, on the wood commodities: ``Sawnwood and Wood-based Panels, SWP'' and the paper commodities, ``Paper and Paperboard, PAP''. The focus was on the newly founded Asia-Pacific Partnership countries for Clean Development and Climate (in short AP6), including Canada, which wants to join the AP6, in relation to the countries of the European Union EU-25. It could be shown that the stocks and stock changes of the HWP in USE follow a simple algorithm of the annual consumption or production and their mean annual growth, for the categories SWP and PAP, provided the mean residence times of the HWP in USE can be estimated. With the information on the fraction of residues entering the landfills and their estimated residence times an equivalent simple expression has been derived for stocks and stock changes of the HWP in LANDFILLS L-F. Their values have been calculated to be approximately 0.5 to 0.7 times smaller than those of the HWP in USE. Still, all stock changes of the HWP in L-F were positive and thus accumulating carbon. However, when methane outgasing within the HWP in L-F had been considered, the calculated Greenhouse Gas Balance was zero or negative under the estimated parameters thus to at least partly compensate the positive storage of carbon in HWP in USE. The percentage of CO2 removed by the HWP in USE in comparison to the annual greenhouse gas emissions varied from 0.3 to 1.7%, with a mean value of 0.8% for the AP6 countries including Canada, in contrast to 1.0% of the EU-25 countries. Despite of the relative small magnitude in relation to the total emission of all GHG this contribution should not be neglected in the GHG Budget of a country.
