Behind the evidence: data and calculations Online at: The user can select, from a drop-down list, the country in question and then the country specific values are inserted into the tool. Task 38
Behind the evidence: data and calculations
Biomass: beyond energy
Biomass: beyond greenhouse gases
Biomass: balancing land use, production and end use What types of trees and crops are best as carbon sink or for bioenergy and wood production? Can land be managed simultaneously as a carbon sink and for bioenergy and fibre production?
