The EF determines the space required to support an activity by means of the area needed to provide the resources consumed and to absorb the wastes generated (Wackernagel and Rees, 1996). In this case, the component method was applied and the mutually exclusive use of land approach was adopted (Monfreda et al.,
2004). Hence, individual EFs were calculated for each flow in the inventory data (in a yearly basis) and were later aggregated, according to Eqs. (1) and (2), respectively.
