And additionally all of the execution account (Fig
Portfolios selected the best mix of regionally differentiated scenarios for each of the three implementation levels, but these levels were developed independently for each scenario and their different ranges may affect their ranking. It is advantageous to generalize the existing results so that we can estimate the net change in GHG emissions for any implementation level within the modeled range. Figure 4a shows the dos070 cumulative mitigation potential (default implementation level, high substitution benefits) for each region plotted against the absolute value of the cumulative change in harvested wood (including roundwood and residues) relative to the baseline, and although the regions differed in size and harvesting activity, there was a well-defined relationship for most scenarios. 4b, Additional file 1: Table S7) resulted in very similar regressions, indicating the cumulative mitigation potential sitio de citas para solteros top gratis could be estimated from the change in harvested wood (relative to the baseline). Slopes from the log–log regressions were close to -1 for the Higher Recovery scenario (between ? 0.5 and ? 1.2 for other scenarios), indicating a 1 MtCO2 increase in cumulative harvested wood in 2070 resulted in a change (relative to the baseline) of ? 1 MtCO2e in cumulative emissions in 2070. The Bioenergy scenario had the greatest variation amongst the regions, which was caused by the degree to which available biomass for bioenergy could meet the local heat demand and substitute high-emissions fossil fuels (See Additional file 2). Normalized net GHG reductions, defined as the net change in cumulative GHG emissions divided by the cumulative change in harvested wood for the Higher Recovery scenario were ? 1 for all implementation levels in most regions, while other scenarios had more regional variability (Additional file 1: Figure S5). For the conservation scenarios, the normalized net GHG reduction was greater for the Harvest Less scenario than for the Restricted Harvest scenario in most regions, indicating that, of the two conservation scenarios, the Harvest Less scenario would have a greater mitigation benefit.
Cumulative net GHG emissions in 2070 compared to the magnitude of the associated cumulative change in harvest C, relative to the baseline, for each region (points) along with linear regressions (lines) for a default scenario implementation level and b all implementation levels, assuming high substitution benefits. 1 MtCO2e) have been excluded.

In terms of individual scenarios, the Restricted Harvest and Harvest Less scenarios have the lowest mitigation costs ($20–$30 per tCO2e), but in terms of socio-economic impacts, there were significant reductions in jobs (Fig. 3c), Gross Domestic Product (GDP) and government revenue (Table 4, Additional file 1: Table S19). The Harvest Residues for Bioenergy, Higher Recovery plus Harvest Residues for Bioenergy, and Longer-Lived Products (LLP) scenarios indicated moderate mitigation costs ($94–$126 per tCO2e). The Higher Recovery scenario with low substitution benefits had positive socio-economic impacts, but indicated the highest mitigation cost ($272 per tCO2e) due to limited mitigation potential. The Higher Recovery scenario had the greatest cost per tonne difference between the low and high substitution benefits, reflecting the significant difference in mitigation potentials depending on how the incremental harvest was used.
Situations associated with bioenergy got extremely high socio-financial impacts just like the bioenergy production out of compile residues is an alternative world and you can produced large revenue.
Modifying the case execution level had little impact on the price for every tonnes on the preservation scenarios, considering the proportional alterations in total cost and you may collective minimization, however it greatly influenced the cost for every tonne inside the bioenergy circumstances once the changing the amount of accumulated collect deposits impacted bioenergy facility options and eliminated fossil fuels. With the exception of conservation situations, for every single circumstance improved efforts, nevertheless the LLP circumstance contributed to losings in the GDP and you may authorities money because the pulp and you can papers marketplace is a whole lot more capital intense much less labor intensive as compared to timber development. The price for every tonne philosophy getting home-based portfolios are among the lower, with reduced variations anywhere between implementation membership and substitution masters (Even more file step one: Dining table S18).
