The carbon footprint in the cradle to gate scenario is expressed in kgCO2 equivalents per square meter
of finished aniline leather. The results are 64.8 kgCO2e/m2 of 1.5 ± 0.1 mm, 74.5 kgCO2e/m2 of 1.7 ±
0.1 mm, 79.6 kgCO2e/m2 of 1.9 ± 0.1 mm and 73 kgCO2e/m2 of all thicknesses. With regard to the
GHG emission of all thicknesses, the deviation percentage for 1.5 ± 0.1 mm. 1.7 ± 0.1 mm, and 1.9 ± 0.1
mm are 11.22%, 2.03% and 9.07% respectively. 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.
