engabstract: Replacing fossil fuel-derived energy with biomass-derived energy is commonly emphasized as a means to reduce CO2 emissions. However, our study highlights the risk of large greenhouse gas emissions when wastes from bioenergy production are recycled as fertilizer for energy crops. Crop management affects the magnitude of these emissions, which in some cases negate a considerable fraction of the global warming savings associated with biofuels.

abstract: Det bliver ofte fremhævet, at CO2-udledningen kan reduceres ved at erstatte fossile brændsler med brændsler produceret på plantebiomasse. Vores studie viser dog, at der er risiko for store drivhusgasudledninger, når restaffald fra bioenergiproduktion føres tilbage til marken som gødning. Afgrøde og dyrkningspraksis påvirker størrelsen af udledningen, som i nogle tilfælde ophæver en betydelig del af drivhusgas-gevinsten forbundet med biobrændsler.
