Note! All results currently only consider the contribution to the carbon pool from the starting point of the simulation an onwards. Any historically extracted volumes from the same areas have - and may still - be a part of the wood products carbon pool, but cannot be included for an arbitrary forest analysis area due to missing data on historical harvest levels. Such an existing carbon pool must be described outside of the current Heureka implementation.

This result group contains: Estimates of carbon pool in harvested wood products stemming from the forest.

Calculation of dead wood

See model description for Harvested Wood Products.

The projected sequestration of carbon in Harvested Wood Products is a result of extracted volumes per assortment, and assumptions of the longevity of the derived products.

Result variables

Note!

All results currently only consider the contribution to the carbon pool from the starting point of the simulation an onwards. Any historically extracted volumes from the same areas have - and may still - be a part of the wood products carbon pool, but cannot be included for an arbitrary forest analysis area due to missing data on historical harvest levels. Such an existing carbon pool must be described outside of the current Heureka implementation.

Wood pulp and Wood based panels are made from Wood fiber commodity, which consists of pulpwood and sawmill by-products in the form of wood chips .

Variable name Unit Description
CO2 Emission tonnes C02 Emission of CO2 related to the extracted volumes stemming from the analysis area.
Inflow Pulp Wood tonnes C Carbon pool inflow related to wood pulp stemming from the Wood fiber commodity extracted in the analysis.
Inflow Sawn Wood tonnes C Carbon pool inflow related to sawnwood stemming from sawtimber extracted in the analysis.
Inflow Wood Based Panels tonnes C Carbon pool inflow related to wood based panels stemming from the wood fiber commodity extracted in the analysis.
Stock Pulp Wood tonnes C Carbon pool stock related to wood pulp stemming from the Wood fiber commodity extracted in the analysis.
Stock Sawn Wood tonnes C Carbon pool inflow related to sawnwood stemming from sawtimber extracted in the analysis.
Stock Wood Based Panels tonnes C Carbon pool inflow related to wood based panels stemming from the wood fiber commodity extracted in the analysis.
