P. Peters (glen.peters@cicero.uio.no) Open Access Solid Earth Open Access The Cryosphere Open Access There are different ways to define the “carbon footprint” or “consumption-based emissions” (Wiedmann and Minx, 2008; Peters, 2008, 2010a; Kanemoto et al., 2012). Table 6 shows the top 10 emitters, and top 10 relative differences, in terms of consumption using two different definitions (Peters et al., 2011a). In the top 10 largest emitters, the differences are generally small, with the largest being the UK (6.7 %) and France (5 %). The mean relative difference for the top 10 countries is 2 %. Geoscientific The largest relative differences are around 50 %, and occur for either small Model countries or countries with poor data. It is not Development possible to know the magnitude or direction of the difference without performing specific calculations (Su and Ang, 2011; Kanemoto et al., 2012). Differences are generally larger for Hydrology small and trade-exposed countries such and as Singapore, Tai- wan, Malaysia, and Belgium (Peters et al., 2011a). The av- Earth System erage difference for the 112 countries and regions in the Sciences database is 6.2 %, signifying that definitions could be one of the reasons for differences in results. While we have only compared two main definitions, other studies can use other different and less standard definitions (cf. Peters and Solli, 2010). Our results clearly show that to ensure robust compar- Ocean Science isons between studies, it is important to control for different definitions.
