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.
