Fig. 5

Exemplary map to visualise the catchment delineated distributions of total direct GHG emissions (mg CO₂eq. MJ⁻¹) for cultivation of rapeseed associated with the different biodiesel configurations within the example region. The variation for the different biodiesel configurations is dominated for this functional unit by the different installed capacities, with larger biodiesel configurations showing lower emissions per mega joule. However, greater spatial variation can be observed when looking at a map of emission intensity per hectare of supplied biomass (see Additional file 1, S.5).
