*3.3. Impact Category*

Two kinds of Life Cycle Impact Assessment (LCIA) methodologies are used to assess the impact. GWP in terms of kg CO2 equivalent and AP in terms of kg SO2 equivalent are analyzed using CML 2001 method. CML 2001 is midpoint approach method which groups results in midpoint during characterization and normalization [48]. CML 2001 was selected since CML 2001 provides the AP value more visually with kg of SO2 equivalent particularly.

PM, POCP and EP were analyzed using ILCD method. ILCD is International reference Life Cycle Data System [49]. Since the method provides analysis results for PM, POCP and EP in terms of mass (kg), the ILCD was selected for better-visualized evaluation, PM in terms of kg PM2.5 equivalent, POCP in terms of kg NMVOC equivalent and EP marine in terms of kg N equivalent.
