“…Research on this topic could be roughly divided into two categories. The first is a separate study on carbon emissions embodied in the trade either internally within a specific-country or the trade between two countries (Lenzen, 1998;Sánchez-Chóliz and Duarte, 2004;Pan et al, 2008;Lin and Sun, 2010;Li and Hewitt, 2008;Yu and Wang, 2010;Xu et al, 2009;Dong et al, 2010;Du et al, 2011;Machado et al, 2001;Mäenpää and Siikavirta, 2007;McGregor et al, 2008;Rhee and Chung, 2006). The second is a comprehensive study on carbon emissions embodied in global trade between major countries or regions in the world (Ahmad and Wyckoff, 2003;Chen and Chen, 2011;Davis et al, 2011;Lenzen et al, 2004;Munksgaard et al, 2005;Peters et al, 2011).…”
