No volatilization is assumed to occur. Nitrogen deposition is assumed to be 13 kg/ha which is a gross average for Denmark (Ellermann et al. 2010). Denitrification and the fraction of this which is N2O is calculated using the SimDen model (Vinther and Hansen 2004) for the particular soil type and fertilizer applications in the different cases. The harvest of oilseeds was based on the yield norms for the specific soil type (Naturerhvervsstyrelsen 2010). From this and a protein content from fodder tables and an N content in proteins of 16%, the amount of N in the harvested oilseeds are calculated. Similarly, the amount of N removed with straw is calculated from the average amount of straw removed (Danish Statistics 2011) and an average content of N of 0.6% (Holmes 1980). Finally, leaching was calculated by assuming the there is no accumulation of N in the field. Table S1 Relative frequency of plant farms, pig farms, on coarse sandy soil, and sandy loam soil in Denmark (Knudsen, 2010, pers. comm. on: Use of fertilizer on Danish agriculture fields, Videncentret for Landbrug, Denmark) Coase sandy soil Sandy loam Pig Farms 0.25 0.41 Plant Farms 0.18 0.16 Fig. S1 Model for nitrogen balance 2 2 Use of pesticides Table S1 summarizes the data used to calculate emissions of pesticides. In the reference system the first number corresponds to the columns and second number to the rows. Total weight per ha: 2.095 kg/(ha*year) of active ingredients. The quantification and modeling of the emission has been done by applying the PEST-LCI model (Birkved and Hauschild 2006).

(1,1): Information from ” Planteværn 2008 Markjournal” (reference 1 – see below) (2,1): Information from ”Planteværn 2008 Markjournal” (reference 1 – see below) (3,1): Middeldatabasen.dk (2010) (reference 3 – see below) (4,1): Middeldatabasen.dk (2010) (reference 3 – see below) 3 (1,7), (1,9), and (1,13): Dash: CAS# 64742-94-5 33-37% (w/w); CAS# 67762-38-3 (w/w) 36-39%; CAS# 68649-29-6 18-20%; CAS# 7664-38-2 3-4% (BASF 2010). According to Middeldatabasen (2010) the density of Dash is 1000g/, however additives, in general, are without any significant biological impact why Dash is not included in the toxicity assessment. (3,6) - the Ferric Phosphate in general do no harm according to US Environmental Protection Agency (2010a) and it is assumed it is not necessary to include this ingredient for toxicity purpose. (3,9) og (3,15) the Manganese and Boron is not used for pesticide purpose. These ingredients are used because the crop is short of these minerals. In this assessment it is assumed that 20% of these minerals are not up taken by the crop and are for this reason emitted to air, soil, and water. (3,8) – Boscalid has not to be found in the available database through SimaPro. However, according to US Environmental Protection Agency (2010b) this pesticide is relative harmless. It has therefore been assumed to be safe to leave out this pesticide from the assessment. (3,16) - Thiacloprid was not to be found in the available database through SimaPro. The best possible alternative to this ingredient is estimated to be Imidacloprid which is from the same group of pesticides – Neonicotinoids which is the most commonly used pesticide. For the ingredients that are not marked have not been able to model using PEST-LCI because these ingredients is not a part of the database in the present version. Based on the ingredients that are available in the database an average ratio of the flows to water, air, and soil have been calculated. 3 Other explanatory variables than presented in the paper In the following some additional explanatory variables are outlined. These variables can either increase or decrease the environmental impact from biodiesel production and use. Feedstock: Chicken fat, soybean, palm oil, algae oils, jatropha oil are all oils which can be used for production of biodiesel. Regions: Different regions that produce biodiesel can explain differences in response parameters. This can be explained by different energy supplies with a higher or lower degree of coal, hydropower, and nuclear power etc. in the grid mix. Also different types of climate will potential could affect the efficiency of the production of the biodiesel. Cars/engine and emission/cleaning technologies: Different types of engine or car technologies can either increase or decrease the environmental impact for use of the biodiesel. Substitutions of other products: Which kind of products that are substituted can also be used as explanatory variables. References BASF (2010) BASF Crop Protection Danmark.
