3.11 Biofuels (original) (raw)
In the FABLE Calculator, besides food and feed, crops and vegetable oils can also be used for biofuel production. This additional demand for biofuel production affects the calculated cropland and associated sustainability indicators. At the same time, biofuels replacing petrol-based fuels have a positive effect on GHG emissions, estimated in the FABLE Calculator by comparing emission factors for gasoline and diesel oil (IPCC) with ethanol and biodiesel (US-RFA 2008), respectively. By default, two biofuel scenarios are defined: stable biofuel demand on 2010 levels and OECD-FAO projections until 2028 (OECD-FAO, 2019), with stable levels afterwards. In the OECD-FAO scenario, shifters for each time step are calculated by dividing the respective time step’s projected biofuel use by the 2010 level. In the stable scenario, all shifters are 1. It should be noted that there are projections for future biofuel demand only for a few countries and regions in the OECD-FAO report. The other countries and/or regions would need to look for alternative biofuel projections.
