  1. The main source for these values is (Weisser 2007). Values marked with * are taken from (Edenhofer et al. 2011), and those marked with ** are from (Johnke 2009). Since it is not specified which sources are included in “Other”, the life-cycle GHG emission factor for this category is calculated as the mean value of all other known factors
