How much bioenergy can Europe produce without harming the environment?

Increasing the use of renewable energies offers significant opportunities for Europe to reduce greenhouse gas emissions and secure its energy supply. However, the substantial rise in the use of biomass from agriculture, forestry and waste for producing energy might put additional pressure on farmland and forest biodiversity as well as on soil and water resources. It may also counteract other current and potential future environmental policies and objectives, such as waste minimisation or environmentally-oriented farming.
