cellulosic bioenergy crops can be used to provide energy in many forms including heat, electricity, gaseous. solid and liquid fuels, A special point of interest is that scenarios with ambitious cli- mate protection targets may require options within the energy sector emissions"). This im- to remove co2 from the atmosphere ("negative plies that uptake of co2 is larger than the amount of human-induced greenhouse gas emissions. One of the few technologies that may re sult in negative emissions is the combination of bioenergy and carbon production is carbon- capture and storage (CCS). as long as bioenergy neutral or at least causes few emissions. But besides other sustainabil- ity concerns like food and water security as well as biodiversity loss, recent research has application of bioenergy in the energy shown that the large-scale and transport sector for climate change mitigation is strongly con nected to emissions from terrestrial ecosystems . The potential of bioenergy to reduce greenhouse gas emissions inherently depends on the source of the biomass, its net emissions and land use effects. There is general con sensus that natural and intact forests. especially in the tropics have
