Big differences between regions: Highest potentials and most efficient use in the Jura and Plateau, big impact of subsidies in the pre-Alps and Alps, small potentials in the southern Alps
Potentials are dependent on forest management, restrictions and supply costs
For example using moderate stock reduction (MSR) scenario:
0.01 CHF more per kWh leads to one million m3 more wood fuel from forests!
This is 50% more wood fuel than used today from forests and half is located in the Jura and Plateau region
Exploiting the ecologically sustainable potential (ESP) offers a large amount of unused resources
Continuous stock increase (CSI; Situation today)
Plateau pre-Alps Alps Jura
Southern Alps
Goal
Estimation of wood fuel from forests for the five production regions
Moderate stock reduction (MSR)
Large stock reduction (LSR)
ESP: Ecologically sustainable potential
Accessible increment per year excluding costs
EESPSUB
Including subsidies for protection forests
EESPMP
Assuming todays market prices for energy
Restrictions
• Mortality
• Protected areas
• Harvest losses
• Material use (less energy friendly market)
Costs (harvesting, chipping and transportation)
Plateau
Results
Sustainable potentials under a less energy friendly market
Continuous stock increase (CSI) Moderate stock reduction (MSR) Large stock reduction (LSR) Ecologically sustainable potential (ESP)
Entire bar:
Share of ecologically economically sustainable potential at market price (EESPMP)
Share of ecologically economically sustainable potential with subsidies in protection forests (EESPSUB)
