Life cycle analysis and monetization of external costs: an application to the comparison between cars

This work evaluated the energy, environmental and economic impacts of a system for biohydrogen production by anaerobic digestion of the by-products of biogas production (digestate) and rice processing (rice husk) through Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCC).

The objective of the study is to compare the externalities generated by different engines of an average private passenger car over the entire life cycle. The comparison includes electric, plug-in hybrid, CNG, gasoline, and diesel engines. The methodology developed to calculate external costs due to different technology options uses damage factors that assume a geographic allocation of potential impacts derived from the application of LCA methodology. For the assessment of external costs, emissions of PM2.5, NOx, SO2, NH3 NMVOC and CO2eq were considered. These damage factors take into account: year of emission; height of emission; geographical area of emission; population density of the region of emission; and socio-economic conditions of the population residing in the region of emission.
