Text in italic indicates a change from the baseline
^aUtilization rates for 4 TSAs were assumed to be lower than 85%
^bSlashburning percentage for coast regions were 15%
^cProportions for 2030 + are listed. In 2016, commodity percentages were 34.3% pulp and paper, 47.1% sawnwood, 16.1% panels, and 2.5% other industrial roundwood production. Baseline percentages were assumed to decrease Pulp and Paper from 2016 until 2030, with corresponding increases in sawnwood and panels
^dLonger-Lived Products (LLP) commodity proportions were implemented starting in 2020, and assumed constant proportions until 2070
