From the review of K. Joseph et al. (2009), the carbon footprint per 100 m2 of leather for all thicknesses was about 15,190 kgCO2 equivalent which could be converted to 151.9 kgCO2e/m2 . This converted value is more than double of the carbon footprint calculated for all thicknesses in this study. This result further emphasizes the importance of performing GHG emissions assessments according to thickness rather than all thicknesses
