 estimate that for "Miscanthus x giganteus" carbon neutrality and even negativity is within reach.The authors argue that a miscanthus crop with a yield of 10 tonnes per hectare per year sequesters so much carbon that the crop more than compensates for both farm operations emissions and transport emissions.The chart on the right displays two CO2 negative miscanthus production pathways, represented in gram CO2-equivalents per megajoule.
