Where, PA e Potential avoidance of ith GHG via materials/energy
recovery or avoided landfilling, EFi e Equivalency factor of ith GHG.
Characteristic coefficients of climate change are evaluated by
weighting the CO2 equivalent using a factor of global warming
potential for a time horizon of 100 years. In this study, IPCC recommended
the latest version of the equivalency factors for GHG to
be used; CO2: 1, CH4: 25, and N2O: 298 (Forster et al., 2007).
