LCA of biomass-based energy systems: A case study for Denmark

► We assessed the environmental impacts of potential energy scenarios for DK. ► Domestic biomass resources were insufficient to cover the energy demand. ► Significant GHGs emissions reductions were achieved in the assessed scenarios. ► RME-biodiesel production for heavy transport resulted in high GW impact due to LUC. ► Eutrophication impact was an effect of crops cultivation and digestate use on land.
