One source of uncertainty is the export of logs, chips, sawdust, shavings and other waste wood from BC to other countries because the receiving manufacturer may have a different product recovery rate or waste handling procedures.
Some of the differences are likely also due to the export of logs, chips, and sawdust (see Methods).
Uncertainties in the BC-HWPv1 estimates of GHG emissions are also due to inter-annual variation in manufacturing, exports of logs, chips and wood products beyond the USA (Figure8), divergent parameters from the literature and data gaps on dumps and landfill management in Canada.

Some of the differences are also due to the export of logs and chips which are therefore manufactured into products in a different jurisdiction.
Indonesia has imposed a permanent ban on exports of logs and wood chips to protect its shrinking forests and curb illegal logging, a forestry official said.
The emissions per km.ton transported were estimated for logs, bundles, chips and bales according to the type of vehicle used and the density of the biomass.
The impressive carbon savings come from the fact that the boilers run on some form of wood, which have absorbed CO2 over their lifetime – either logs, wood chips or pellets made from compressed sawdust.
Salted the night before, then rinsed in lake water, the salmon fillet that would be "hot smoked" took on a deep rosy hue over a patient fire of birch logs and alder chips.
That means a lot of chips.
