6.10 Harvested wood products (CRF 4G)
6.10.1 Description
New Zealand is reporting for the harvested wood products pool for the first time in the
2015 submission. In 2013, the net emissions from harvested wood products were
–10,295.6 kt CO 2 -e. This is –8,326.4 kt CO 2 -e (422.8 per cent) higher than the 1990 level
of –1,969.2 kt CO 2 -e. This is because the rate of harvest in New Zealand has
increased since 1990. This is illustrated in the roundwood production statistics shown in
figure 6.10.1.

New Zealand has a large planted forest estate that provides the majority of wood products
consumed domestically and exported in either product or raw material form. These forests
were planted from the 1920s to supplement and eventually replace the harvesting of
natural forests. Forest planting from the 1960s provides a resource specifically
established to provide products to the export market. New Zealand currently processes
under 50 per cent of its annual harvest. The remaining harvest is exported in raw material
